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…
Schrodinger Cat States for Quantum Information Processing
H. Jeong, T. C. Ralph
We extensively discuss how Schrodinger cat states (superpositions of well-separated coherent states) in optical systems can be used for quantum information processing.
Adaptive Phase Measurements in Linear Optical Quantum Computation
T. C. Ralph, A. P. Lund, H. M. Wiseman
Photon counting induces an effective nonlinear optical phase shift on certain states derived by linear optics from single photons. Although this no nlinearity is nondeterministic,…
Optimal photons for quantum information processing
Peter P. Rohde, Timothy C. Ralph, Michael A. Nielsen
Photonic quantum information processing schemes, such as linear optics quantum computing, and other experiments relying on single-photon interference, inherently require complete p…
