Efficient classical simulation of measurements in optical quantum information
Stephen D. Bartlett, Barry C. Sanders
We present conditions for the efficient simulation of a broad class of optical quantum circuits on a classical machine: this class includes unitary transformations, amplification,…
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…
From Qubits to Continuous-Variable Quantum Computation
Barry C Sanders, Stephen D. Bartlett, Hubert de Guise
By encoding a qudit in a harmonic oscillator and investigating the d --> infinity limit, we give an entirely new realization of continuous-variable quantum computation. The general…
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…
Efficient Classical Simulation of Optical Quantum Circuits
Stephen D. Bartlett, Barry C. Sanders
We identify a broad class of physical processes in an optical quantum circuit that can be efficiently simulated on a classical computer: this class includes unitary transformations…
