Phase-space representation of classical simulability for arbitrary bosonic encodings
Eloi Descamps, Astghik Saharyan, Arne Keller +1
Phase-space representations can be used to reveal resources for quantum computational advantage. In odd-dimensional qudit systems, states and operations admitting non-negative quas…
The Role of Symmetry in Generalized Hong-Ou-Mandel Interference and Quantum Metrology
Éloi Descamps, Arne Keller, Pérola Milman
The Hong-Ou-Mandel interferometer is a foundational tool in quantum optics, with both fundamental and practical significance. Earlier works identified that input-state symmetry und…
Resources for bosonic metrology: quantum-enhanced precision from a superselection rule perspective
Astghik Saharyan, Eloi Descamps, Arne Keller +1
Bosonic systems, particularly in quantum optics and atomic physics, are leading platforms for achieving quantum enhanced precision in parameter estimation. By exploiting properties…
Unified framework for bosonic quantum information encoding, resources and universality from superselection rules
Eloi Descamps, Astghik Saharyan, Adrien Chivet +2
A convenient way to represent quantum optical states is through the quadrature basis of single-modes of the field. This framework provides intuitive definitions for quasi-classical…
