Complementarity Analysis of Interference between Frequency-Displaced Photonic Wave-Packets
Gustavo C. Amaral, Elisa F. Carneiro, Guilherme P. Temporão +1
The complementarity relation between the visibility and the spectral distinguishability of frequency-displaced photonic wave-packets in a Hong-Ou-Mandel interferometer is studied.…
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…
Linear-Optic Heralded Photon Source
Thiago Ferreira da Silva, Gustavo C. Amaral, Guilherme P. Temporão +1
We present a Heralded Photon Source based only on linear optics and weak coherent states. By time-tuning a Hong-Ou-Mandel interferometer fed with frequency-displaced coherent state…
Safeguarding Quantum Key Distribution through Detection Randomization
Thiago Ferreira da Silva, Gustavo C. do Amaral, Guilherme B. Xavier +2
We propose and experimentally demonstrate a scheme to render the detection apparatus of a Quantum Key Distribution system immune to the main classes of hacking attacks in which the…
