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,…
Classical Dynamics as Constrained Quantum Dynamics
Stephen D. Bartlett, David J. Rowe
We show that the classical mechanics of an algebraic model are implied by its quantizations. An algebraic model is defined, and the corresponding classical and quantum realizations…
Quantum Teleportation of Optical Quantum Gates
Stephen D. Bartlett, William J. Munro
We show that a universal set of gates for quantum computation with optics can be quantum teleported through the use of EPR entangled states, homodyne detection, and linear optics a…
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…
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…
Continuous-variable quantum teleportation of entanglement
Tyler J. Johnson, Stephen D. Bartlett, Barry C. Sanders
Entangled coherent states can be used to determine the entanglement fidelity for a device that is designed to teleport coherent states. This entanglement fidelity is universal, in…
