Non-Gaussianity from superselection rules

Nicolas Moulonguet, Eloi Descamps, José Lorgeré +3

The quantum theory of the electromagnetic field enables the description of multiphoton states exhibiting nonclassical statistical properties, often reflected in non-Gaussian phase-…

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…

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…

Effective models for quantum optics with multilayer open cavities

Astghik Saharyan, Juan-Rafael Álvarez, Axel Kuhn +1

Effective models to describe the dynamics of an open cavity have been extensively discussed in the literature. In many of these models the cavity leakage to the outside is treated…

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…

Propagating single photons from an open cavity: Description from universal quantization

Astghik Saharyan, Benjamin Rousseaux, Zsolt Kis +2

Over the last decades, quantum optics has evolved from high quality factor cavities in the early experiments toward new cavity designs involving leaky modes. Despite very reliable…

Light-matter interaction in open cavities with dielectric stacks

Astghik Saharyan, Juan-Rafael Álvarez, Thomas H. Doherty +2

We evaluate the exact dipole coupling strength between a single emitter and the radiation field within an optical cavity, taking into account the effects of multilayer dielectric m…

Microscopic and phenomenological models of driven systems in structured reservoirs

Gian Luca Giorgi, Astghik Saharyan, Stéphane Guérin +2

We study the paradigmatic model of a qubit interacting with a structured environment and driven by an external field by means of a microscopic and a phenomenological model. The val…

Finite temperature fermionic condensate in a conical space with a circular boundary and magnetic flux

Aram A. Saharian, Eugênio R. Bezerra de Mello, Astghik A. Saharyan

We investigate the edge effects on the finite temperature fermionic condensate (FC) for a massive fermionic field in a (2+1)-dimensional conical spacetime with a magnetic flux loca…
