Covariant Affine Integral Quantization(s)
Jean Pierre Gazeau, Romain Murenzi
Covariant affine integral quantization of the half-plane is studied and applied to the motion of a particle on the half-line. We examine the consequences of different quantizer ope…
Probing photon correlations in the dark sites of geometrically frustrated cavity lattices
W. Casteels, R. Rota, F. Storme +1
We theoretically explore the driven-dissipative physics of geometrically frustrated lattices of cavity resonators with relatively weak nonlinearities, i.e. a photon-photon interact…
General conditions for maximal violation of non-contextuality in discrete and continuous variables
A. Laversanne-Finot, A. Ketterer, M. R. Barros +4
The contextuality of quantum mechanics, i.e. the measurement outcome dependence upon previously made measurements, can be shown by the violation of inequalities based on measuremen…
Quantum information processing in phase space: A modular variables approach
A. Ketterer, A. Keller, S. P. Walborn +2
Binary quantum information can be fault tolerantly encoded in states defined in infinite dimensional Hilbert spaces. Such states define a computational basis, and permit a perfect…
Quantum state tomography with non-instantaneous measurements, imperfections and decoherence
Pierre Six, Philippe Campagne-Ibarcq, Igor Dotsenko +3
Tomography of a quantum state is usually based on positive operator-valued measure (POVM) and on their experimental statistics. Among the available reconstructions, the maximum-lik…
Precision measurement of the branching fractions of the 5p 2 P 1/2 state in 88 Sr + with a single ion in a micro fabricated surface trap
Jean-Pierre Likforman, Vincent Tugayé, Samuel Guibal +1
We measured the branching fractions for the decay of the 5p 2 P 1/2 state of 88 Sr + by applying a recently demonstrated photon-counting sequential method (M. Ramm et al., Phys. Re…
