Accuracy of minimal and optimal qubit tomography for finite-length experiments
Alex Ling, Antia Lamas-Linares, Christian Kurtsiefer
Practical quantum state tomography is usually performed by carrying out repeated measurements on many copies of a given state. The accuracy of the reconstruction depends strongly o…
Experimental quantum key distribution based on a Bell test
Alexander Ling, Matthew P. Peloso, Ivan Marcikic +3
We report on a complete free-space field implementation of a modified Ekert91 protocol for quantum key distribution using entangled photon pairs. For each photon pair we perform a…
Absolute emission rates of Spontaneous Parametric Down Conversion into single transverse Gaussian modes
Alexander Ling, Antia Lamas-Linares, Christian Kurtsiefer
We provide an estimate on the absolute values of the emission rate of photon pairs produced by spontaneous parametric down conversion in a bulk crystal when all interacting fields…
Experimental Falsification of Leggett's Non-Local Variable Model
Cyril Branciard, Alexander Ling, Nicolas Gisin +3
Bell's theorem guarantees that no model based on local variables can reproduce quantum correlations. Also some models based on non-local variables, if subject to apparently "reason…
