Entanglement between Two Uses of a Noisy Multipartite Quantum Channel Enables Perfect Transmission of Classical Information
Runyao Duan, Yaoyun Shi
Suppose that senders want to transmit classical information to receivers with zero probability of error using a noisy multipartite communication channel. The senders are al…
Local distinguishability of orthogonal 2\otimes3 pure states
Yu Xin, Runyao Duan
We present a complete characterization for the local distinguishability of orthogonal pure states except for some special cases of three states. Interestingly, we find…
Exact Quantum Search by Parallel Unitary Discrimination Schemes
Xiaodi Wu, Runyao Duan
We study the unsorted database search problem with items from the viewpoint of unitary discrimination. Instead of considering the famous Grover's the bounded-erro…
Locally Indistinguishable Subspaces Spanned by Three-Qubit Unextendible Product Bases
Runyao Duan, Yu Xin, Mingsheng Ying
We study the local distinguishability of general multi-qubit states and show that local projective measurements and classical communication are as powerful as the most general loca…
Conditions for entanglement transformation between a class of multipartite pure states with generalized Schmidt decompositions
Yu Xin, Runyao Duan
In this note we generalize Nielsen's marjoization criterion for the convertibility of bipartite pure states [Phys. Rev. Lett \textbf{83}, 436(1999)] to a special class of multipart…
Existence of Universal Entangler
Jianxin Chen, Runyao Duan, Zhengfeng Ji +2
A gate is called entangler if it transforms some (pure) product states to entangled states. A universal entangler is a gate which transforms all product states to entangled states.…
