An electrically injected photon-pair source at room temperature
Fabien Boitier, Adeline Orieux, Claire Autebert +7
One of the main challenges for future quantum information technologies is miniaturization and integration of high performance components in a single chip. In this context, electric…
Direct high-resolution characterization of quantum correlations via classical measurements
Andreas Eckstein, Guillaume Boucher, Aristide Lemaître +6
Quantum optics plays a central role in the study of fundamental concepts in quantum mechanics, and in the development of new technological applications. Typical experiments employ…
Continuous discretization of infinite dimensional Hilbert spaces
P. Vernaz-Gris, A. Ketterer, A. Keller +3
In quantum theory, observables with a continuous spectrum are known to be fundamentally different from those with a discrete and finite spectrum. While some fundamental tests and a…
Quantizations from (P)OVM's
Hervé Bergeron, Evaldo M. F. Curado, Jean-Pierre Gazeau +1
We explain the powerful role that operator-valued measures can play in quantizing any set equipped with a measure, for instance a group (resp. group coset) with its invariant (resp…
A revised uncertainty budget for measuring the Boltzmann constant using the Doppler Broadening Technique on ammonia
Cyril Lemarchand, Sinda Mejri, Papa Lat Tabara Sow +6
We report on our on-going effort to measure the Boltzmann constant, kB, using the Doppler Broadening Technique. The main systematic effects affecting the measurement are discussed.…
Integral quantizations with two basic examples
Jean Pierre Gazeau, Herve Bergeron
The paper is devoted to integral quantization, a procedure based on operator-valued measure and resolution of the identity. We insist on covariance properties in the important case…
