Coherent control of microwave pulse storage in superconducting circuits
Patrick M. Leung, Barry C. Sanders
Coherent pulse control for quantum memory is viable in the optical domain but nascent in microwave quantum circuits. We show how to realize coherent storage and on-demand pulse ret…
Spectral Effects of Fast Response Cross Kerr Non-Linearity on Quantum Gate
P. M. Leung, T. C. Ralph, William J. Munro +1
According to idealized models, a strong Kerr non-linearity may be used to build optical quantum gates for optical quantum information processing by inducing conditional phase shift…
Spectral Effects of Strong Chi-2 Non-Linearity for Quantum Processing
P. M. Leung, William J. Munro, Kae Nemoto +1
Optical non-linearity can be used for parametric amplification and producing down-converted entangled photon pairs that have broad applications. It is known that weak non…
Optical Zeno Gate: Bounds for Fault Tolerant Operation
Patrick M. Leung, Timothy C. Ralph
In principle the Zeno effect controlled-sign gate of Franson et al's (PRA 70, 062302, 2004) is a deterministic two-qubit optical gate. However, when realistic values of photon loss…
Improving the Fidelity of Optical Zeno Gates via Distillation
P. M. Leung, T. C. Ralph
We have modelled the Zeno effect Control-Sign gate of Franson et al (PRA 70, 062302, 2004) and shown that high two-photon to one-photon absorption ratios, , are needed for high…
