1. Introduction

The emergence of the Internet of Things (IoT) has led to an exponential growth in data generation, creating the need for higher computing power and storage [1]. This has resulted in the development of cloud computing, which has greatly enhanced the capabilities of IoT applications. However, the current cloud computing infrastructure may not be sufficient to meet the growing demands of IoT applications, particularly in latency and security [2], this is where quantum-edge cloud computing comes in. Quantum computing is a new paradigm that uses quantum bits (qubits) instead of classical bits, which enables quantum computers to perform specific calculations much faster than classical computers. While quantum computers are still in their infancy, they hold great promise for many applications, including IoT [3]. The Internet of Things (IoT) is reshaping the technological landscape, heralding an era where connectivity and computation converge at an unprecedented scale [4]. This convergence necessitates a computational paradigm capable of supporting the massive data volumes generated by IoT devices, alongside the need for real-time processing, enhanced security, and energy efficiency [5] [6]. Traditional cloud computing, while pivotal in the rise of IoT, struggles to meet these demands due to inherent limitations in latency and scalability [7]. To address these challenges, Quantum-Edge Cloud Computing (QECC) emerges as a compelling solution, integrating the quantum computing’s computational prowess, edge computing’s low-latency benefits, and cloud computing’s scalability and resource availability. Quantum computing introduces a paradigm shift, offering processing capabilities that transcend traditional computational limits, thereby enhancing the efficiency and security of data processing tasks essential for IoT applications [8]. This integration is particularly crucial in addressing the security vulnerabilities present in conventional cloud computing frameworks, leveraging quantum cryptography to fortify data integrity and confidentiality across IoT networks. Edge computing plays a pivotal role in this triad by processing data closer to its source, significantly reducing latency and bandwidth usage. This localized processing capability is vital for time-sensitive IoT applications, ensuring timely decision-making and action [9] [10]. However, the successful deployment of edge computing within IoT infrastructures hinges on addressing challenges related to hardware requirements, security, and system complexity [11] [12]. Cloud computing, with its inherent scalability and resource abundance, offers a robust foundation for supporting the expansive data and computational needs of IoT systems. By integrating with quantum and edge computing, cloud platforms can overcome traditional limitations, facilitating a more dynamic and efficient IoT ecosystem [4] [13]. Despite its advantages, this integrated approach necessitates tackling challenges related to data privacy, interoperability, and the management of distributed computing resources [14] [15].

The QECC is a computing model that aims to solve the various challenges modern IoT systems face. This model combines the power of quantum computing, edge computing, and cloud computing to improve computational efficiency and security and to develop innovative IoT applications. This paper explores the theoretical foundations of QECC, its potential to revolutionize IoT, and how it can mitigate current challenges through technological advancements and real-world applications.

2. Literature Review

This model capitalizes on quantum computing’s unparalleled processing power and the unique security features provided by quantum cryptography, setting a new standard for computational speed and data security. Their work lays the foundation for future explorations into quantum-enhanced cloud services that could dramatically transform computational paradigms [8].

Recent simulations have further demonstrated quantum computing’s impactful role in enhancing computational speeds and security measures [19] [20]. For instance, a 2021 study simulated a quantum computing scenario that showed a reduction in processing time by up to 40% for complex data algorithms, compared to traditional computing methods [21]. Additionally, quantum cryptography has been shown to significantly bolster security, with simulated attacks demonstrating that quantum-encrypted networks are substantially more resistant to cyber threats than their classical counterparts. Edge computing is crucial in reducing latency and improving the responsiveness of IoT systems [22]. A practical case study on edge computing was conducted in a smart city project in 2022, where edge computing devices utilized AI algorithms to manage traffic flow in real-time [23]. The results indicated a 30% improvement in traffic management efficiency, showcasing how edge computing significantly reduces system latency and increases the operational effectiveness of IoT applications in urban environments (CityTech Collaborative, 2022).

Cloud computing provides the backbone for scalable and flexible IoT applications by offering extensive storage capacities and computational resources [24]. [7] detailed how cloud platforms could accommodate the vast array of IoT devices and their data needs, providing scalable solutions across various service models such as Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS) [7]. To address scalability, a recent pilot program tested cloud services’ ability to dynamically scale during peak loads in a nationwide retail chain’s IoT deployment [25]. The study reported that adaptive scaling technologies enabled a 50% increase in data handling capacity without compromising performance, underscoring the critical role of cloud computing in managing large-scale IoT operations efficiently (National Retail Corporation, 2023). The principles of superposition and entanglement, as discussed by [8], underscore quantum computing’s potential to revolutionize data processing speeds and security, setting a precedent for quantum enhanced IoT systems.

Quantum-edge cloud computing combines the power of quantum computing with the distributed computing paradigm of edge computing [29]. This enables IoT applications to process data in real time while ensuring data security and reducing latency. Quantum-edge cloud computing also has the potential to significantly reduce the energy consumption of IoT applications by using quantum computing to optimize energy usage [16]. This can lead to more sustainable and efficient operation of IoT devices and networks. Quantum-edge cloud computing can also enhance the scalability and reliability of IoT applications by leveraging the computational capabilities of quantum computing to handle large volumes of data and complex algorithms.

The present study examines (Table 3) the relationship between processing speed and error rates in traditional computing and Quantum-Edge Cloud Computing (QECC). The following analysis is presented to illustrate the average error rates associated with different processing speeds for traditional computing and Quantum-Edge Cloud Computing (QECC), as illustrated in Figure 4 and Figure 5, respectively. As depicted in Figure 4, traditional computing exhibits the highest average error rate for the processing speed of 10 seconds. This observation suggests that tasks that require a more considerable processing time may be more prone to errors.

Figure 4. Processing speed of traditional computing.

Conversely, Figure 5 demonstrates that within QECC, the processing speeds of 5 seconds and 8 seconds exhibit higher average error rates compared to other speeds. This observation implies that despite the general aim of QECC to minimize error rates, specific processing speeds still experience higher incidences of errors. Consequently, these specific thresholds where error rates increase may point to optimization challenges that QECC needs to address.

Figure 6 and Figure 7 provide a comparative analysis of error rates associated with various data throughput speeds for two computing frameworks: Traditional Computing and Quantum-Edge Cloud Computing (QECC). In Figure 6, data throughput of 80 MB/sec exhibits a discernibly higher error rate when compared to lower throughputs for traditional computing. This observation is indicative that as data throughput increases, the system is more susceptible to errors, likely due to limitations in handling higher data volumes efficiently.

Figure 7, under the QECC framework, highlights that the highest data throughput tested, 180 MB/sec, demonstrates a significantly higher error rate than the other speeds. The result suggests that QECC, like traditional computing, faces challenges at higher throughputs, potentially indicating a need for further optimization to maintain accuracy at these elevated data transfer rates. These findings underscore that despite QECC’s advancements, managing error rates at high throughputs remains a critical issue for traditional and quantum-edge computing frameworks.

Concurrently, the error rate was halved from 0.10% to 0.05%. Similarly, the Public Safety Monitoring system of the same complex saw a significant increase in throughput from 50 MB/sec to 150 MB/sec while simultaneously reducing the error rate from 0.20% to 0.10%. In healthcare monitoring, the Patient Monitoring System at Asgar Ali Hospital demonstrated a twofold increase in throughput from 20 MB/sec to 40 MB/sec, with negligible change to the error rate, suggesting a significant improvement without compromising data integrity. The Emergency Response System at Anwar Khan Modern Hospital also experienced an increase in throughput from 10 MB/sec to 30 MB/sec and decreased error rates from 0.05% to 0.02%. In the industrial IoT domain, the Manufacturing Process Control system at Pran Apparels, Bangladesh, exhibited a substantial increase in data throughput from 80 MB/sec to 180 MB/sec while reducing error rates from 0.30% to 0.15%.

6. Quantum Algorithms for Edge Computing: Challenges and Techniques

The study discusses the need to optimize quantum algorithms for edge computing in the context of Quantum-Edge Cloud Computing (QECC), but it falls short in providing specific examples or concrete techniques. A more detailed exploration of quantum algorithms and their applicability to Internet of Things (IoT) tasks are critical to demonstrate QECC’s practical relevance.

6.1. Challenges in Optimizing Quantum Algorithms for Edge Computing

Quantum algorithms, though powerful, face unique challenges when applied to edge computing environments, especially within IoT systems.

1) Limited Resources at the Edge: Edge devices typically have constrained computational and energy resources compared to centralized cloud systems. Therefore, quantum algorithms must be designed or optimized to operate efficiently under these limitations. Algorithms that minimize quantum gate operations and circuit depth are essential to reduce the energy consumption and computational load.

2) Decoherence and Error Rates: Quantum systems are prone to decoherence, where qubits lose their quantum state due to external interference. This introduces significant error rates, particularly when applied to complex, real-time IoT tasks. Techniques such as quantum error correction or noise-resilient algorithms could mitigate these issues but require further optimization for edge environments.

3) Real-time Processing: Quantum algorithms must be adapted to handle real-time data streams at the edge. Unlike traditional batch processing, real-time applications, such as healthcare monitoring or traffic management in smart cities, require quantum algorithms that can process data continuously and deliver results with minimal latency.

6.2. Concrete Techniques for Optimizing Quantum Algorithms

To make quantum algorithms more suitable for edge computing in IoT applications, several specific techniques can be employed:

1) Variational Quantum Algorithms (VQAs): These algorithms, such as Quantum Approximate Optimization Algorithm (QAOA) and Variational Quantum Eigen solver (VQE), are designed to run on near-term quantum devices and can be particularly effective for optimization tasks in IoT systems. VQAs work by using a classical optimizer to adjust the parameters of a quantum circuit, allowing them to adapt to the limited resources available at the edge.

2) Quantum Machine Learning (QML): Quantum machine learning algorithms like Quantum Support Vector Machines (QSVMs) and Quantum Neural Networks (QNNs) hold promise for real-time pattern recognition and anomaly detection in IoT environments. These algorithms can enhance edge devices’ ability to handle large volumes of data by performing more efficient, high-dimensional data analysis, reducing both time and space complexity.

3) Quantum Cryptographic Protocols: Given the security demands of IoT systems, Quantum Key Distribution (QKD) can be integrated into edge computing environments to enhance data security. QKD ensures that encryption keys exchanged between edge devices are protected from eavesdropping, providing a level of security that classical cryptographic methods cannot match.

4) Hybrid Quantum-Classical Algorithms: To overcome the limitations of edge devices, hybrid algorithms that combine quantum and classical computing can be employed. For instance, edge devices can use classical methods to preprocess data before sending the more complex calculations to a quantum processor, optimizing the overall system efficiency. This can be particularly useful in applications such as smart healthcare or industrial IoT, where latency and accuracy are critical.

6.3. Application-Specific Optimization

The suitability of quantum algorithms varies depending on the specific IoT application:

  • Healthcare Monitoring: Algorithms optimized for real-time anomaly detection and predictive analytics can help monitor patients’ vital signs, identifying potential emergencies faster than traditional systems.

  • Smart City Infrastructure: Quantum algorithms can optimize traffic flow, reduce congestion, and improve public safety by processing vast amounts of sensor data in real time, enhancing the effectiveness of urban planning efforts.

  • Industrial IoT: In manufacturing environments, quantum algorithms can be used for process optimization and defect detection, significantly improving operational efficiency and reducing errors in production systems.

7. Discussion

The empirical data presented in the study demonstrates that Quantum Edge Cloud Computing (QECC) can significantly enhance processing speeds and reduce error rates in Internet of Things (IoT) applications when compared to traditional computing. This improvement is particularly noteworthy in Industrial IoT, where quantum computing’s theoretical predictions regarding computational efficiency are validated. The integration of edge computing has also shown a positive correlation with reduced latency, confirming the literature’s hypotheses about the benefits of localized data processing. However, the error rates associated with QECC indicate that challenges remain in optimizing these systems for error resilience, particularly at higher processing speeds and data throughputs.

While QECC offers clear advantages, further research is needed to address these challenges. For example, at higher throughputs—such as 180 MB/sec—QECC systems still exhibit increased error rates, suggesting a need for optimization to maintain accuracy. Furthermore, QECC’s reliance on edge computing introduces new challenges related to the limitations of edge devices, such as restricted processing power or network bandwidth. These constraints can lead to higher error rates, especially in real-time analytics for healthcare monitoring.

In traditional computing frameworks, errors are often attributed to latency, scalability limitations, and security vulnerabilities. High latency in transmitting data between IoT devices and centralized cloud servers, particularly in real-time applications like smart city infrastructure and healthcare monitoring, can result in processing delays and errors. Additionally, traditional cloud systems often struggle to scale, leading to bottlenecks and higher error rates in large-scale IoT networks, especially in Industrial IoT, where larger data volumes overwhelm traditional systems. Furthermore, traditional encryption methods are more susceptible to cyberattacks, which compromise data integrity, as seen in the Public Safety Monitoring System in Bangladesh.

Although QECC mitigates many of these issues, it faces its own set of challenges. Quantum decoherence, a phenomenon where qubits lose their quantum state due to environmental interference, can introduce errors during calculations or encryption processes. Additionally, QECC requires further algorithmic refinement, particularly for processing speeds between 5 and 8 seconds, where elevated error rates persist. Quantum-resistant encryption methods are also needed to safeguard against emerging security threats without increasing error rates. To enhance QECC’s effectiveness, several areas for improvement have been identified. First, quantum algorithms need to be refined to handle larger data volumes without increasing error rates. Second, improving hardware capabilities at the edge of the network is crucial for ensuring robust performance, particularly in smart city infrastructure and Industrial IoT applications. Finally, developing quantum-resistant encryption techniques will help mitigate the risks introduced by quantum decoherence, ensuring data security without compromising system performance.

While QECC presents a promising solution for IoT applications by improving speed, reducing latency, and enhancing data security, further research is necessary to fully optimize these systems. The findings underscore QECC’s potential but also caution against a one-size-fits-all approach, emphasizing the need for tailored solutions that consider each application domain’s unique demands and technical challenges. By addressing these underlying error sources, QECC can become a more reliable and efficient solution for IoT applications across various sectors.

2) Diversification of Case Studies: To understand the broader implications of QECC across various geographies and sectors, future research should include a more diverse range of case studies, including those outside Bangladesh.

3) Interoperability and Standardization: As QECC becomes more prevalent, establishing interoperability standards will be critical. Future research should address the seamless integration of quantum, edge, and cloud computing within existing IoT ecosystems.

4) Energy Efficiency: Given the energy demands of computing, especially quantum computing, future research should also focus on making QECC more energy-efficient and environmentally sustainable.

By adhering to these recommendations and focusing on the outlined research directions, the potential of QECC to transform IoT applications can be fully realized, leading to a new standard of performance, security, and scalability in the IoT domain.

9. Conclusion

Our investigation into the theoretical foundations and real-world applications reveals QECC as a robust solution for enhancing data processing speeds, security, and scalability across IoT systems. Key findings emphasize the critical need for developing quantum-resistant encryption methods to protect against future quantum threats, alongside addressing scalability and standardization challenges to ensure widespread adoption. Future research focusing on optimizing quantum algorithms for edge environments and enhancing interoperability through standardized protocols will be pivotal. As QECC continues to evolve, it promises to overcome current IoT limitations, heralding a new era of technological innovation that is both secure and efficient, driven by interdisciplinary collaboration and continuous advancements.

Limitations of This Study

The study on Quantum-Edge Cloud Computing (QECC) for IoT applications has some limitations. It relies on data from only a few sectors in Bangladesh, and quantum computing technology is still in the early development stages. The case studies selected represent only a narrow slice of potential uses, and the integration of quantum, edge, and cloud computing poses complex challenges. IoT systems are commonly constructed using conventional computing methods, potentially lacking compatibility with quantum computing. Consequently, organizations must allocate resources towards acquiring new infrastructure and expertise to seamlessly integrate quantum technologies into their current IoT systems. Quantum hardware is another limitation. Quantum processors are currently in their initial phases, with only a handful of companies providing access to such computing resources. This scarcity poses a challenge for organizations aiming to test and expand quantum computing applications. Resource constraints and evolving cyber threats are also significant barriers. Finally, the study suggests optimizing quantum algorithms for edge computing, but practical techniques are not substantiated. Further research is necessary to overcome these obstacles and fully realize QECC’s potential in the IoT sector.
