Operator quantum error correction
David W. Kribs, Raymond Laflamme, David Poulin +1
This paper is an expanded and more detailed version of our recent work in which the Operator Quantum Error Correction formalism was introduced. This is a new scheme for the error c…
A Single Photon Source With Linear Optics and Squeezed States
Casey R. Myers, Marie Ericsson, Raymond Laflamme
Quantum information processing using photons has recently been stimulated by the suggestion to use linear optics, single photon sources and detectors. The recent work by Knill has…
Noiseless subsystems and the structure of the commutant in quantum error correction
J. A. Holbrook, D. W. Kribs, R. Laflamme
The effect of noise on a quantum system can be described by a set of operators obtained from the interaction Hamiltonian. Recently it has been shown that generalized quantum error…
Noiseless subsystems for collective rotation channels in quantum information theory
J. A. Holbrook, D. W. Kribs, R. Laflamme +1
Collective rotation channels are a fundamental class of channels in quantum computing and quantum information theory. The commutant of the noise operators for such a channel is a C…
Post-processing with linear optics for improving the quality of single-photon sources
Dominic W. Berry, Stefan Scheel, Casey R. Myers +3
Triggered single-photon sources produce the vacuum state with non-negligible probability, but produce a much smaller multiphoton component. It is therefore reasonable to approximat…
Introduction to NMR Quantum Information Processing
R. Laflamme, E. Knill, D. G. Cory +11
After a general introduction to nuclear magnetic resonance (NMR), we give the basics of implementing quantum algorithms. We describe how qubits are realized and controlled with RF…
