Dead-time optimization to increase secure distance range in prepare and measure quantum key distribution protocols
Carlos Wiechers, J. L. Lucio, Xóchitl Sánchez-Lozano +2
Afterpulsing is a factor limiting the distance over which discrete-variable quantum key distribution systems are secure, and a common feature in single-photon detectors. The releva…
Z-scan applied to phosphate glasses doped with Er-Yb and silver nanoparticles
C. Wiechers, M. A. Martinez-Gamez, M. A. Vallejo-Hernandez +4
We report on the use of Z-scan technique with a beam composed with two modes, to probe the nonlinear optical properties of phosphate glasses doped with Er-Yr and silv…
800 nm pumped SPDC from chirped crystals
X. Sánchez-Lozano, C. Wiechers, J. L. Lucio
We consider crystal chirp effects on SPDC when pumping at 800 nm. The typical distribution produced in frequency-momentum space is a pop tab-like structure which turns out to be su…
Spontaneous parametric down conversion in chirped, aperiodically-poled crystals
X. Sanchez-Lozano, Jose Luis Lucio
We present a theoretical analysis of the process of spontaneous parametric down conversion (SPDC) in a non-linear crystal characterized by a linearly-chirped X(2) grating along the…
On the relationship between pump chirp and single-photon chirp in spontaneous parametric downconversion
X. Sanchez-Lozano, A. B. U'Ren, J. L. Lucio
We study the chronocyclic character, i.e. the joint temporal and spectral properties, of the single-photon constituents of photon pairs generated by spontaneous parametric down con…
Charge asymmetries in e+e- -> pi+ pi- gamma at the phi resonance
A. Gallegos, J. L. Lucio, G. Moreno +1
We consider the forward-backward pion charge asymmetry for the e^{+}e^{-}\toπ^{+}π^{-}γprocess. At tree level we consider bremsstrahlung and double resonance contributions. Althoug…
