Quantum key distribution with realistic heralded single photon sources
Mikolaj Lasota, Rafal Demkowicz-Dobrzanski, Konrad Banaszek
We analyze theoretically performance of four-state quantum key distribution protocols implemented with a realistic heralded single-photon source. The analysis assumes a noisy model…
Generation of spatially pure photon pairs in a multimode nonlinear waveguide using intermodal dispersion
Michal Karpinski, Czeslaw Radzewicz, Konrad Banaszek
We present experimental realization of type-II spontaneous parametric down-conversion in a periodically poled potassium titanyl phosphate (KTiOPO4) nonlinear waveguide. We demonstr…
Quantum Key Distribution with Qubits Encoded in Qutrit
R. Kumar, R. Demkowicz-Dobrzanski, K. Banaszek
We present a novel one-way quantum key distribution protocol based on 3-dimensional quantum state, a qutrit, that encodes two qubits in its 2-dimensional subspaces. The qubits hold…
