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…
Transitions as the Native Objects of Dispersive Light-Matter Dynamics
Mohamed Meguebel, Maxime Federico, Louis Garbe +2
The paper presents a framework that treats light‑matter transitions as the primary dynamical objects, providing a compact diagrammatic method for multiphoton processes and enabling…
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…
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…
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…
