Quantum random number generation enhanced by weak-coherent states interference
T. Ferreira da Silva, G. B. Xavier, G. C. Amaral +2
We propose and demonstrate a technique for quantum random number generation based on the random population of the output spatial modes of a beam splitter when both inputs are simul…
Sub-Poisson States Heralded at a Hong-Ou-Mandel Interference Peak
G. C. Amaral, F. Calliari, T. Ferreira da Silva +2
A peak in coincidence events has been observed in a modified Hong-Ou-Mandel interferometer fed with weak coherent states inside the region of overlapping wave-packets. The inversio…
Few-Photon Heteorodyne Spectroscopy
Gustavo C Amaral, Thiago Ferreira da Silva, Guilherme P Temporão +1
We perform a high resolution Fourier Transform Spectroscopy of optical sources in the few-photon regime based on the phenomenon of two-photon interference in a beam splitter. From…
Employing long fibre-optical Mach- Zehnder interferometers for quantum cryptography with orthogonal states
G. B. Xavier, G. P. Temporao, J. P. von der Weid
We experimentally demonstrate that a long distance actively stabilized Mach-Zehnder fibre optical interferometer can be used to reliably implement the GV95 quantum cryptography pro…
Active polarization control for quantum communication in long-distance optical fibers with shared telecom traffic
G. B. Xavier, G. Vilela de Faria, T. Ferreira da Silva +2
We experimentally demonstrate the compatibility of wavelength multiplexed active polarization stabilization for quantum communication in an optical fiber carrying telecom traffic.…
