Airborne Cold-Atom Gravimeter

Laboratory : ONERA
Place : Palaiseau
Manager : Yannick Bidel
Offre

Scientific activity

Today, the wave nature of matter is harnessed to build interferometers capable of measuring accelerations and rotations with extremely high precision. In these sensors, the source of the matter waves consists of a gas of laser-cooled atoms. The interferometer is constructed by subjecting the free-falling atoms to a series of laser pulses that split and then recombine the matter wave. This technology has, in particular, enabled the development of gravimeters capable of measuring gravity aboard ships or aircraft, with an accuracy of up to 5 × 10⁻⁶ m/s². ONERA has made a significant contribution to the development of this technology through the first demonstrations of gravimetric measurements in marine and airborne environments. ONERA is currently developing a new generation of instruments that are more compact and precise, capable not only of measuring the amplitude of the gravitational field but also of determining its orientation. As part of this effort, a new gravimeter has been built, and initial, very promising tests have been conducted on a motion simulator.

The proposed internship will involve participating in the first airborne test of this second-generation gravimeter. Initially, the intern will establish a calibration procedure for the auxiliary sensors required for the gravimeter’s operation. Subsequently, the intern will participate in an in-flight measurement campaign in the Faroe Islands. Finally, they will contribute to the processing and analysis of the data acquired during the flights. This internship will allow the intern to acquire skills at the intersection of several fields: quantum physics, high-precision metrology, instrumentation, and data processing. The internship may be followed by a thesis focusing on the further development of this quantum gravimeter, with the goal of performing vector measurements of the gravitational field.

Quantum Metrology of Electromagnetic Fields Using Rydberg Atoms in Optical Tweezers

Laboratory : ONERA
Place : Palaiseau
Manager : S. Schwartz / A. Bonnin
Offer

Scientific activity

Rydberg atoms, which have a very large principal quantum number preceding 1, possess remarkable properties for quantum technologies, including strong interactions that enable the generation of entanglement between atoms, and strong coupling to electromagnetic fields, which allows for the measurement of these fields with very high precision.

This internship is part of a project aimed at exploring a new generation of electromagnetic field sensors using cold Rydberg atoms. The idea is to combine the high sensitivity of Rydberg atoms with the high degree of control and coherence that can be achieved with cold atoms trapped in optical tweezers. This paves the way for new applications in a variety of fields, such as THz imaging, electromagnetic detection, the calibration of light shifts in atomic clocks, and quantum metrology experiments where entanglement between atoms is harnessed to improve measurement sensitivity.

The experimental setup demonstrated innovative methods for measuring a microwave field using cold Rydberg atoms [Phys. Rev. Applied 22, 044039; arXiv:2608.07260]. The goal of this internship is to explore new techniques for measuring electromagnetic fields using cold Rydberg atoms in optical traps.

As part of ONERA’s DPHY/SLM unit—a globally recognized leader in cold-atom-based sensors—you will also have the opportunity to collaborate with ONERA’s Electromagnetics and Radar Department as well as with our academic and industrial partners (SYRTE, Aimé Cotton Laboratory, LuMIn, IEMN, Thales TRT).

Molecular membrane fabrication for quantum technologies

Laboratory : Institut de Recherche de Chimie Paris
Place : Paris 5e
Manager : Diana Serrano
Offre

Scientific description

Rare-earth-based materials are promising platforms for quantum technologies because they combine long-lived optical and spin coherences, with nuclear spin coherence times reaching several hours in optimized crystalline hosts [1–4]. Their integration into nanophotonic structures, however, requires materials that preserve these quantum properties while being compatible with optical microcavities, waveguides and other on-chip architectures [3,5]. Molecular crystals provide an attractive alternative to conventional inorganic hosts, offering a high degree of chemical and structural tunability together with potentially versatile routes towards device integration [6].

We recently demonstrated europium molecular crystals with optical homogeneous linewidths in the tens-of-kHz range, several orders of magnitude narrower than those typically observed in molecular systems [7,8]. This platform has enabled efficient optical spin initialization, coherent light storage using an atomic frequency comb, and optical control of ion–ion interactions towards quantum-gate schemes [8]. More recently, optically detected nuclear magnetic resonance and millisecond nuclear spin coherence were demonstrated in single crystals of the same [Eu(BA)4(pip)] complex [9], further establishing these materials as promising optical–spin quantum interfaces.

So far, however, these properties have been investigated in millimetre-sized bulk crystals. Integration with photonic structures would instead benefit from thin, flat crystalline membranes that can be deterministically positioned onto a photonic chip while retaining the optical coherence of the bulk material. Adapting mechanical exfoliation and dry-transfer approaches originally developed for two dimensional materials [10,11], and encouraged by the narrow optical lines recently reported in layered rare-earth crystals [12], we have recently started exploring the fabrication of thin membranes from europium molecular crystals (Fig. 1). Preliminary experiments have produced crystalline flakes tens of micrometres in lateral size and with thicknesses approaching or below the micrometre scale, together with a first successful transfer onto a silicon carbide substrate.

Objectives

The central objective of this internship is to establish a reproducible route for fabricating europium molecular membranes and, crucially, to determine whether their exceptional optical properties are preserved after exfoliation and transfer. The student will optimize the mechanical exfoliation conditions to increase the yield of thin, large-area flakes; develop deterministic dry-transfer protocols onto photonic substrates such as SiC, SiO2/Si and glass; characterize membrane thickness, morphology and crystalline quality using optical interference microscopy, atomic force microscopy and Raman spectroscopy; and investigate their luminescence and optical homogeneous linewidths at cryogenic temperatures using spectral hole burning. Comparison with bulk crystals will allow the influence of exfoliation, reduced thickness and substrate coupling on the optical coherence of the molecular material to be established.

This work will be carried out within the CQSD team at the Institut de Recherche de Chimie Paris (IRCP). More information about the research group can be found at www.cqsd.fr.

Implementation of an adaptive optical system for trapping dipolarquantum gases

Laboratory : Laboratoire de Physique des Lasers
Place : USPN, Villetaneuse
Manager : Lucas LAVOINE, lucas.lavoine@univ-paris13.fr

In the recent years the chromium team at LPL has pioneered studies of quantum magnetism using quantum gases of chromium atoms trapped in optical lattices. Chromium is a species which has a high permanent magnetic moment leading to significant dipolar interactions. Measurement of quantum correlations has led to original studies of quantum thermalization [1,2,3], a process in which an isolated system evolves towards equilibrium through the growth of entanglement. By controlling the depth of the optical lattices, it is possible to study the competition between dipolar interactions, contact interactions, and transport across the superfluid–Mott phase transition [4,5].

We are currently rebuilding the experiment to achieve new scientific objectives. In particular, we have acquired a spatial light modulator based on an array of micromirrors and known as digital micromirror device (DMD). DMDs enable the amplitude of the laser used for trapping atoms to be controlled at the micrometre scale, allowing the possibility to create trapping potentials with arbitrary shapes in the atomic plane. During the internship, the student will design and set up an adaptive optical system and then develop algorithms to generate and control the resulting potentials.

The student will interact with all team members: Lucas Lavoine (associate professor), Benjamin Pasquiou (CNRS engineer), Laurent Vernac (professor), Fatima Rahmouni (postdoctoral researcher) and Esther Fromm (PhD student). See https://gqm.lpl.univ‐paris13.fr/ for recent publications and thesis of the team.
