Efficient Toffoli Gates Using Qudits
T. C. Ralph, K. J. Resch, A. Gilchrist
The simplest decomposition of a Toffoli gate acting on three qubits requires {\em five} 2-qubit gates. If we restrict ourselves to controlled-sign (or controlled-NOT) gates this nu…
A Model for Non-Linear Quantum Evolution based on Time Displaced Entanglement
T. C. Ralph
We discuss a model for non-linear quantum evolution based on the idea of time displaced entanglement, produced by taking one member of an entangled pair on a round trip at relativi…
Time Displaced Entanglement and Non-Linear Quantum Evolution
T. C. Ralph
We discuss time displaced entanglement, produced by taking one member of a Bell pair on a round trip at relativistic speeds, thus inducing a time-shift between the pair. We show th…
Components for Optical Qubits in the Radio Frequency Basis
E. H. Huntington, T. C. Ralph
We describe a scheme for the encoding and manipulation of single photon qubits in radio frequency sideband modes using standard optical elements.
Proposal for a simple quantum error correction test gate in linear optics
T. C. Ralph
We describe a linear quantum optical circuit capable of demonstrating a simple quantum error correction code in a four photon experiment.
