Conditions For Entanglement Transformation Between A Class Of Multipartite Pure States With Generalized Schmidt Decompositions

Xin Yu; Duan Runyao (Amer Physical Soc, 2007)

We generalize Nielsen's majorization criterion for the convertibility of bipartite pure states [Phys. Rev. Lett. 83, 436 (1999)] to a special class of multipartite pure states with generalized Schmidt decompositions.
Distinguishability of Quantum States by Separable Operations

Duan Runyao; Feng Yuan; Xin Yu; Ying Mingsheng (IEEE-Inst Electrical Electronics Engineers Inc, 2009)

In this paper, we study the distinguishability of multipartite quantum states by separable operations. We first present a necessary and sufficient condition for a finite set of orthogonal quantum states to be distinguishable ...
Local Distinguishability Of Orthogonal 2 Circle Times 3 Pure States

Xin Yu; Duan Runyao (Amer Physical Soc, 2008)

We present a complete characterization for the local distinguishability of orthogonal 2 circle times 3 pure states except for some special cases of three states. Interestingly, we find there is a large class of four or ...
Locally Indistinguishable Subspaces Spanned By Three-Qubit Unextendible Product Bases

Duan Runyao; Xin Yu; Ying Mingsheng (Amer Physical Soc, 2010)

We study the local distinguishability of general multiqubit states and show that local projective measurements and classical communication are as powerful as the most general local measurements and classical communication. ...
