Distinguishing Arbitrary Multipartite Basis Unambiguously Using Local Operations and Classical Communication
Runyao Duan, Yuan Feng, Zhengfeng Ji +1
We show that an arbitrary basis of a multipartite quantum state space consisting of distant parties such that the th party has local dimension always contains at least…
Optimal dense coding with arbitrary pure entangled states
Yuan Feng, Runyao Duan, Zhengfeng Ji
We examine dense coding with an arbitrary pure entangled state sharing between the sender and the receiver. Upper bounds on the average success probability in approximate dense cod…
Boundary effect of deterministic dense coding
Zhengfeng Ji, Yuan Feng, Runyao Duan +1
We present a rigorous proof of an interesting boundary effect of deterministic dense coding first observed by Mozes et al. [Phys. Rev. A 71, 012311 (2005)]. Namely, it is shown tha…
Entanglement Is Not Necessary for Perfect Discrimination between Unitary Operations
Runyao Duan, Yuan Feng, Mingsheng Ying
We show that a unitary operation (quantum circuit) secretely chosen from a finite set of unitary operations can be determined with certainty by sequentially applying only a finite…
Identification and Distance Measures of Measurement Apparatus
Zhengfeng Ji, Yuan Feng, Runyao Duan +1
We propose simple schemes that can perfectly identify projective measurement apparatus secretly chosen from a finite set. Entanglements are used in these schemes both to make possi…
