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…
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…
Experimental observation of fractional topological phases with photonic qudits
A. A. Matoso, X. Sánchez-Lozano, W. M. Pimenta +6
Geometrical and topological phases play a fundamental role in quantum theory. Geometric phases have been proposed as a tool for implementing unitary gates for quantum computation.…
Experimental scheme for unambiguous discrimination of linearly independent symmetric states
O. Jiménez, X. Sánchez-Lozano, A. Delgado +1
We propose an optimal discrimination scheme for a case of four linearly independent nonorthogonal symmetric quantum states, based on linear optics only. The probability of discrimi…
