Characterizing an Entangled-Photon Source with Classical Detectors and Measurements
Lee A. Rozema, Chao Wang, Dylan H. Mahler +4
Quantum state tomography (QST) is a universal tool for the design and optimization of entangled-photon sources. It typically requires single-photon detectors and coincidence measur…
Discrete Feynman propagator for the Weyl quantum walk in 2+1 dimensions
G. M. D'Ariano, N. Mosco, P. Perinotti +1
Recently quantum walks have been considered as a possible fundamental description of the dynamics of relativistic quantum fields. Within this scenario we derive the analytical solu…
Symmetric angular momentum coupling, the quantum volume operator and the 7-spin network: a computational perspective
Dimitri Marinelli, Annalisa Marzuoli, Vincenzo Aquilanti +3
A unified vision of the symmetric coupling of angular momenta and of the quantum mechanical volume operator is illustrated. The focus is on the quantum mechanical angular momentum…
A Fabry-Perot interferometer with quantum mirrors: nonlinear light transport and rectification
F. Fratini, E. Mascarenhas, L. Safari +5
Optical transport represents a natural route towards fast communications, and it is currently used in large scale data transfer. The progressive miniaturization of devices for info…
An integrated source of spectrally filtered correlated photons for large scale quantum photonic systems
Nicholas C. Harris, Davide Grassani, Angelica Simbula +7
We demonstrate the generation of quantum-correlated photon-pairs combined with the spectral filtering of the pump field by more than 95dB using Bragg reflectors and electrically tu…
Quasi-quantization: classical statistical theories with an epistemic restriction
Robert W. Spekkens
A significant part of quantum theory can be obtained from a single innovation relative to classical theories, namely, that there is a fundamental restriction on the sorts of statis…
