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…
Estimation of nonclassical independent Gaussian processes by classical interferometry
László Ruppert, Radim Filip
We propose classical interferometry with low-intensity thermal radiation for the estimation of nonclassical independent Gaussian processes in material samples. We generally determi…
Pauli channel tomography with unknown channel directions
Dániel Virosztek, László Ruppert, Katalin M. Hangos
In this paper we estimate the parameters of the qubit Pauli channel using the channel matrix formalism. The main novelty of this work is that we do not assume the directions of the…
