Polarisation drift compensation in an 8 km long Mach-Zehnder fibre-optical interferometer for quantum communication
G. B. Xavier, T. R. da Silva, G. P. Temporao +1
We experimentally stabilise the polarisation drift between the arms of an 8 km-long fibre-optical Mach-Zehnder interferometer, while simultaneously compensating the phase fluctuati…
Experimental polarization encoded quantum key distribution over optical fibres with real-time continuous birefringence compensation
G. B. Xavier, N. Walenta, G. Vilela de Faria +4
In this paper we demonstrate an active polarization drift compensation scheme for optical fibres employed in a quantum key distribution experiment with polarization encoded qubits.…
Full polarization control for fiber optical quantum communication systems using polarization encoding
G. B. Xavier, G. Vilela de Faria, G. P. Temporao +1
A real-time polarization control system employing two nonorthogonal reference signals multiplexed in either time or wavelength with the data signal is presented. It is shown, theor…
Mid-Infrared Single Photon Counting
Guilherme Temporao, Sebastien Tanzilli, Hugo Zbinden +4
We report a procedure to detect mid-infrared single photons at 4.65 um via a two-stage scheme based on Sum Frequency Generation, using a Periodically Poled Lithium Niobate (PPLN) n…
