Many-spin entanglement in multiple quantum NMR with a dipolar ordered initial state
Ilia D. Lazarev, Edward. B. Feldman
Multiple quantum (MQ) NMR with a dipolar ordered initial state opens new possibilities for the exploration of many-spin entanglement. In this paper, we investigate many-spin entang…
Optimal Cloning of Quantum States with a Fixed Failure Rate
E. Bagan, V. Yerokhin, A. Shehu +2
Perfect cloning of a known set of states with arbitrary prior probabilities is possible if we allow the cloner to sometimes fail completely. In the optimal case the probability of…
A Geometric Approach to Quantum State Separation
Emilio Bagan, Vadim Yerokhin, Andi Shehu +2
Probabilistic quantum state transformations can be characterized by the degree of state separation they provide. This, in turn, sets limits on the success rate of these transformat…
Probabilistically Perfect Cloning of Two Pure States: A Geometric Approach
Vadim Yerokhin, Andi Shehu, Edgar Feldman +2
We solve the long-standing problem of making n perfect clones from m copies of one of two known pure states with minimum failure probability in the general case where the known sta…
Extracting information from a qubit by multiple observers: Toward a theory of sequential state discrimination
Janos Bergou, Edgar Feldman, Mark Hillery
We discuss sequential unambiguous state-discrimination measurements performed on the same qubit. Alice prepares a qubit in one of two possible states. The qubit is first sent to Bo…
Quantum walks as a probe of structural anomalies in graphs
Mark Hillery, Hongjun Zheng, Edgar Feldman +2
We study how quantum walks can be used to find structural anomalies in graphs via several examples. Two of our examples are based on star graphs, graphs with a single central verte…
