Simple and Rigorous Proof Method for the Security of Practical Quantum Key Distribution in the Single-Qubit Regime Using Mismatched Basis Measurements
Michel Boyer, Gilles Brassard, Nicolas Godbout +2
Quantum key distribution (QKD) protocols aim at allowing two parties to generate a secret shared key. While many QKD protocols have been proven unconditionally secure in theory, pr…
Entanglement-enhanced probing of a delicate material system
Florian Wolfgramm, Chiara Vitelli, Federica A. Beduini +2
Quantum metrology uses entanglement and other quantum effects to improve the sensitivity of demanding measurements. Probing of delicate systems demands high sensitivity from limite…
Large nonlinear Kerr effect in graphene
Han Zhang, Stephane Virally, Qiaoliang Bao +4
Under strong laser illumination, few-layer graphene exhibits both a transmittance increase due to saturable absorption and a nonlinear phase shift. Here, we unambiguously distingui…
Ultra-Narrow Faraday Rotation Filter at the Rb D1 Line
Joanna A. Zielińska, Federica A. Beduini, Nicolas Godbout +1
We present a theoretical and experimental study of the ultra-narrow bandwidth Faraday anomalous dispersion optical filter (FADOF) operating at the rubidium D1 line (795 nm). This a…
Testing nonlocality over 12.4 km of underground fiber with universal time-bin qubit analyzers
Felix Bussieres, Joshua A. Slater, Jeongwan Jin +2
We experimentally demonstrate that the nonlocal nature of time-bin entangled photonic qubits persists when one or two qubits of the pair are converted to polarization qubits. This…
Limits of heralded single photon sources based on parametric photon pair generation
Stéphane Virally, Suzanne Lacroix, Nicolas Godbout
We derive calculations on the statistics of a heralded single photon source based on parametric photon pair generation. These calculations highlight fundamental and practical limit…
