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…
Transfer of Nonclassical Properties from A Microscopic Superposition to Macroscopic Thermal States in The High Temperature Limit
Hyunseok Jeong, Timothy C. Ralph
We present several examples where prominent quantum properties are transferred from a microscopic superposition to thermal states at high temperatures. Our work is motivated by an…
Frequency and temporal effects in linear optical quantum computing
Peter P. Rohde, Timothy C. Ralph
Typically linear optical quantum computing (LOQC) models assume that all input photons are completely indistinguishable. In practice there will inevitably be non-idealities associa…
Communicating continuous quantum variables between different Lorentz frames
Pieter Kok, Timothy C. Ralph, Gerard J. Milburn
We show how to communicate Heisenberg-limited continuous (quantum) variables between Alice and Bob in the case where they occupy two inertial reference frames that differ by an unk…
