Analog-to-digital conversion in the quantum regime
Thomas Pousset, Matteo Schiavon, Guillaume Ricard +3
Digital signal processing has become essential in quantum optics, particularly for continuous-variable (CV) information encoding, enabling coherent detection schemes and mitigation…
On the zeros of the stellar representation in the discrete cylinder
Nicolas Fabre
The discrete cylinder phase space offers a natural setting for twisted photons, Josephson junctions, and certain bosonic codes. In that context, we build a number-of-zeros hierarch…
Effective Hamiltonians in Cavity and Waveguide QED from Transition-Operator Diagrammatic Perturbation Theory
Mohamed Meguebel, Maxime Federico, Louis Garbe +2
We propose an adiabatic-elimination formalism in the dispersive regime based on a transition-centric perturbation theory. The perturbative expansion is recast into a diagrammatic f…
Transitions as the Native Objects of Dispersive Light-Matter Dynamics
Mohamed Meguebel, Maxime Federico, Louis Garbe +2
We introduce a framework where light-matter transitions, rather than states, are the primary dynamical objects. Successive compositions of elementary transitions yield multiphoton…
Time-frequency Talbot effect as Clifford operations on entangled time-frequency GKP states
Thomas Pousset, Romain Dalidet, Laurent Labonté +1
The Talbot effect -- a near-field diffraction phenomenon in which a periodic wavefront self-images at regular distances -- can be transposed to the time--frequency domain via the s…
Robustness and optimization of N00N-state interferometry
Romain Dalidet, Anthony Martin, Louis Bellando +4
Quantum-enhanced interferometry is often discussed in terms of ideal resources and asymptotic scalings, whereas in practice its performance is set by a delicate interplay between l…
Quantum-enhanced phase sensitivity in an all-fiber Mach-Zehnder interferometer
Romain Dalidet, Sébastien Tanzilli, Gregory Sauder +3
Recent advances in quantum photonics have enabled increasingly robust protocols in optical phase estimation, achieving precisions beyond the standard quantum limit and approaching…
Resource-optimal quantum mode parameter estimation with multimode Gaussian states
Maximilian Reichert, Mikel Sanz, Nicolas Fabre
Quantum mode parameter estimation determines parameters governing the shape of electromagnetic modes occupied by a quantum state of radiation. Canonical examples, time delays and f…
Superselection rules and bosonic quantum computational resources
Eloi Descamps, Nicolas Fabre, Astghik Saharyan +2
We present a method to systematically identify and classify quantum optical non-classical states as classical/non-classical based on the resources they create on a bosonic quantum…
Photonic quantum information processing using the frequency continuous-variable of single photons
Nicolas Fabre, Ulysse Chabaud
The celebrated Hong--Ou--Mandel effect illustrates the richness of two-photon interferometry. In this work, we demonstrate that this extends to the realm of time-frequency interfer…
Quantum metrology using time-frequency as quantum continuous variables: Resources, sub shot-noise precision and phase space representation
Eloi Descamps, Nicolas Fabre, Arne Keller +1
We study the role of the electromagnetic field's frequency in time precision measurements using single photons as a paradigmatic system. For such, we independently identify the con…
The Hong-Ou-Mandel experiment: from photon indistinguishability to continuous variables quantum computing
Nicolas Fabre, Maria Amanti, Florent Baboux +3
We extensively discuss the Hong-Ou-Mandel experiment taking an original phase-space-based perspective. For this, we analyze time and frequency variables as quantum continuous varia…
Producing delocalized frequency-time Schrödinger cat-like states with HOM interferometry
N. Fabre, J. Belhassen, A. Minneci +7
In the late 80's, Ou and Mandel experimentally observed signal beatings by performing a non-time resolved coincidence detection of two photons having interfered in a balanced beam…
Engineering two-photon wavefunction and exchange statistics in a semiconductor chip
S. Francesconi, F. Baboux, A. Raymond +6
High-dimensional entangled states of light provide novel possibilities for quantum information, from fundamental tests of quantum mechanics to enhanced computation and communicatio…
