A photon density wavefunction
Stéphane Virally
Maxwell's equations in the vacuum can be formally cast in the form of Schrödinger's equation. Unfortunately, the vector to which this equation directly applies is not a wavefunctio…
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…
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…
A microstructured fiber source of photon pairs at widely separated wavelengths
Joshua A. Slater, Jean-Simon Corbeil, Stephane Virally +6
We demonstrate a source of photon pairs with widely separated wavelengths, 810 nm and 1548 nm, generated through spontaneous four-wave mixing in a microstructured fiber. The second…
