	1	Randomly Generating Four Mixed Bell-Diagonal States with a Concurrences Sum to Unity显示文摘A two-qubit system in quantum information theory is the simplest bipartite quantum system and its concurrence for pure and mixed states is well known.As a subset of two-qubit systems,Bell-diagonal states can be depicted by a very simple geometrical representation of a tetrahedron with sides of length 2√2.Based on this geometric representation,we propose a simple approach to randomly generate four mixed Bell decomposable states in which the sum of their concurrence is equal to one.

	2	Kochen-Specker Sets with a Mixture of 16 Rank-1 and 14 Rank-2 Projectors for a Three-Qubit System显示文摘Kochen-Specker(KS)theorem denies the possibility for the noncontextual hidden variable theories to reproduce the predictions of quantum mechanics.A set of projection operators(projectors)and bases used to show the impossibility of noncontextual definite values assignment is named as the KS set.Since one KS set with a mixture of 16 rank-1 projectors and 14 rank-2 projectors was proposed in 1995[Kernaghan M and Peres A Phys.Lett.A 198(1995)1]for a three-qubit system,there have been plenty of the same type KS sets and we propose a systematic way to produce them.We also propose a probabilistic state-dependent proof of the KS theorem that mainly focuses on the values assignment for all the rank-2 projectors.

	3	State-Independent Proof of Kochen–Specker Theorem with Thirty Rank-Two Projectors显示文摘The Kochen–Specker theorem states that noncontextual hidden variable theories are incompatible with quantum mechanics.We provide a state-independent proof of the Kochen–Specker theorem using the smallest number of projectors,i.e.,thirty rank-2 projectors,associated with the Mermin pentagram for a three-qubit system.
