Slow light with three-level atoms in metamaterial waveguides
Benjamin R. Lavoie, Patrick M. Leung, Barry C. Sanders
Metamaterial is promising for enhancing the capability of plasmonic devices. We consider a cylindrical waveguide with three-level Λ atoms embedded in the dielectric core. By compar…
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…
Low-loss surface modes and lossy hybrid modes in metamaterial waveguides
B. R. Lavoie, P. M. Leung, B. C. Sanders
We show that waveguides with a dielectric core and a lossy metamaterial cladding (metamaterial-dielectric guides) can support hybrid ordinary-surface modes previously only known fo…
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…
