講座內容:
A pure quantum state of N subsystems with d levelseach is said to be k-uniform if all of its reductions to k qudits aremaximally mixed. There is a link between quantum entangled states andorthogonal arrays (OAs). By using the construction methods and Hamming distances of OAs for the theory ofquantum information,we canconstruct a series of infinite classes of irredundant orthogonal arrays(IrOAs). Then we answered the open questions of whether there exist 3-uniformstates of N qubits and 2-uniform states of N qutrits, and whether 3-uniformstates of qudits (d > 2) for high values of N can be explicitly constructedin 《PhysicalReview A》. And we canprovide a positive answer to some open problems in《PhysicalReview Letters》and 《PhysicalReview A》.
