Resources required for exact remote state preparation
Dominic W. Berry
It has been shown [M.-Y. Ye, Y.-S. Zhang, and G.-C. Guo, Phys. Rev. A 69, 022310 (2004)] that it is possible to perform exactly faithful remote state preparation using finite class…
On improving single photon sources via linear optics and photodetection
Dominic W. Berry, Stefan Scheel, Barry C. Sanders +1
In practice, single photons are generated as a mixture of vacuum with a single photon with weights 1-p and p, respectively; here we are concerned with increasing p by directing mul…
Numerical Analysis of the Capacities for Two-Qubit Unitary Operations
Dominic W. Berry, Barry C. Sanders
We present numerical results on the capacities of two-qubit unitary operations for creating entanglement and increasing the Holevo information of an ensemble. In all cases tested,…
Optimal Remote State Preparation
Dominic W. Berry, Barry C. Sanders
We prove that it is possible to remotely prepare an ensemble of non-commuting mixed states using communication equal to the Holevo information for this ensemble. This remote prepar…
Relation between classical communication capacity and entanglement capability for two-qubit unitary operations
Dominic W. Berry, Barry C. Sanders
Two-qubit operations may be characterized by their capacities for communication, both with and without free entanglement, and their capacity for creating entanglement. We establish…
Relations for classical communication capacity and entanglement capability of two-qubit operations
Dominic W. Berry, Barry C. Sanders
Bipartite operations underpin both classical communication and entanglement generation. Using a superposition of classical messages, we show that the capacity of a two-qubit operat…
