High-dimensional decoy-state quantum key distribution over 0.3 km of multicore telecommunication optical fibers
G. Cañas, N. Vera, J. Cariñe +11
Multiplexing is a strategy to augment the transmission capacity of a communication system. It consists of combining multiple signals over the same data channel and it has been very…
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…
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…
Impact of Raman scattered noise from multiple telecom channels on fiber-optic quantum key distribution systems
Thiago Ferreira da Silva, Guilherme B. Xavier, Guilherme P. Temporão +1
In this paper we analyze the impact of the spontaneous Raman scattered noise generated from multiple optical classical channels on a single quantum key distribution channel, all wi…
Quantum key distribution with untrusted detectors
P. Gonzalez, L. Rebon, T. Ferreira da Silva +6
Side-channel attacks currently constitute the main challenge for quantum key distribution (QKD) to bridge theory with practice. So far two main approaches have been introduced to a…
Polarization-stable long-distance interference of independent photons for quantum communications
T. Ferreira da Silva, D. Vitoreti, G. B. Xavier +2
Interference between fully-independent faint laser sources over two 8.5-km full polarization-controlled fiber links was performed, with stable visibility of 47.8%, an essential ste…
Proof-of-principle demonstration of measurement-device-independent quantum key distribution using polarization qubits
T. Ferreira da Silva, D. Vitoreti, G. B. Xavier +3
We perform a proof-of-principle demonstration of the measurement-device-independent quantum key distribution (MDI-QKD) protocol using weak coherent states and polarization-encoded…
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.…
