ABSTRACT:
The numbers of local complimentary inequivalent graph
states for 9, 10 and 11 qubit systems are 440, 3132, 40457,
respectively. We calculate the entanglement, the lower and upper bounds of the
entanglement and obtain the closest product states for all these graph states.
New patterns of closest product states are analyzed.
