Fading channel estimation for free-space continuous-variable secure quantum communication

László Ruppert, Christian Peuntinger, Bettina Heim +6

We investigate estimation of fluctuating channels and its effect on security of continuous-variable quantum key distribution. We propose a novel estimation scheme which is based on…

Stabilization of transmittance fluctuations caused by beam wandering in continuous-variable quantum communication over free-space atmospheric channels

Vladyslav C. Usenko, Christian Peuntinger, Bettina Heim +6

Transmittance fluctuations in turbulent atmospheric channels result in quadrature excess noise which limits applicability of continuous-variable quantum communication. Such fluctua…

Efficient Quantum Walk Circuits for Metropolis-Hastings Algorithm

Jessica Lemieux, Bettina Heim, David Poulin +2

We present a detailed circuit implementation of Szegedy's quantization of the Metropolis-Hastings walk. This quantum walk is usually defined with respect to an oracle. We find that…
