Spatial symmetry in few-photon interference and quantum metrology
Éloi Descamps, Pérola Milman
In previous work [Physical Review Letters, 136(6):060807, 2026], we developed a symmetry-based framework for generalized Hong-Ou-Mandel interference and its applications to quantum…
PhD thesis: Modes, States, and Symmetries in quantum Optics for quantum Information and Metrology
Éloi Descamps
This thesis explores the role of modes, states, and symmetries in quantum optics, within the context of quantum information and quantum metrology. It proposes a unified framework t…
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…
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…
Measuring entanglement along collective operators
Éloi Descamps, Arne Keller, Pérola Milman
We introduce a framework for the study of multiparty entanglement by analyzing the behavior of collective variables. Throughout the manuscript, we explore a specific type of multip…
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…
Noisy certification of continuous variables graph states
Éloi Descamps, Damian Markham
Continuous variables (CV) offer a promising platform for the development of various applications, such as quantum communication, computing, and sensing, and CV graph states represe…
Gottesman-Kitaev-Preskill encoding in continuous modal variables of single photons
Éloi Descamps, Arne Keller, Pérola Milman
GKP states, introduced by Gottesman, Kitaev, and Preskill, are continuous variable logical qubits that can be corrected for errors caused by phase space displacements. Their experi…
On The Stabilizer Formalism And Its Generalization
Éloi Descamps, Borivoje Dakić
The standard stabilizer formalism provides a setting to show that quantum computation restricted to operations within the Clifford group are classically efficiently simulable: this…
Approaching maximal precision of Hong-Ou-Mandel interferometry with non-perfect visibility
Othmane Meskine, Eloi Descamps, Arne Keller +4
In quantum mechanics, the precision achieved in parameter estimation using a quantum state as a probe is determined by the measurement strategy employed. The ultimate quantum limit…
Time-frequency metrology with two single-photon states: phase space picture and the Hong-Ou-Mandel interferometer
Éloi Descamps, Arne Keller, Pérola Milman
We use time-frequency continuous variables as the standard framework to describe states of light in the subspace of individual photons occupying distinguishable auxiliary modes. We…

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…
