Fast Polarization Switch for Polarization-Based Quantum Communication
Vinicius M. Lima, Felipe Calliari, Joaquim D. Garcia +4
We present a complete optoelectronic unit for polarization visualization, switching and control. The system is based on an FPGA unit and comprises: an acquisition unit containing a…
Stable single-photon interference in a 1 km fiber-optical Mach-Zehnder interferometer with continuous phase adjustment
G. B. Xavier, J. P. von der Weid
We experimentally demonstrate stable and user-adjustable single-photon interference in a 1 km long fiber- optical Mach-Zehnder interferometer, using an active phase control system…
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…
