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…
