报告题目Orthogonal arrays and quantum entangled states

报告人:庞善起 教授

报告摘要A pure quantum state of N subsystems, each with d levels, is said to be k-uniform if all of its reductions to k qudits are maximally mixed. There is a close relation between quantum entangled states and orthogonal arrays (OAs). When the Hamming distances of OAs are applied to the theory of quantum information, we can construct a series of infinite classes of irredundant orthogonal arrays (IrOAs). Then we answer the open questions of whether there exist 3-uniform states of N qubits and 2-uniform states of N qutrits, and whether 3-uniform states of qudits (d > 2) for high values of N can be explicitly constructed inPhysical Review A. And we provide a positive answer to some open problems inPhysical Review Lettersand Physical Review A.
