Postdoctoral & PhD Positions in cavity/waveguide QED

In two setups we are studying crystallization and self-ordering phenomena in systems where the emerging ordered structure has more degrees of freedom with respect to what can be obtained in a stationary wave cavity. The atoms are trapped in a traveling wave cavity, where they interact with several cavity modes, or within the core of a photonic crystal fiber, where they see a continuum of electromagnetic modes. In either case no boundary conditions are imposed to the emerging optical lattice, and the transition from homogeneous to periodic order consists in a crystallization of both light and ultracold atoms breaking a continuous translational symmetry. The scheme would allow the observation of supersolid-like components and quasi-crystals.

iXAtom: quantum sensors to navigate on and under water

The iXAtom joint laboratory aims to develop a new generation of inertial sensors, based on the use of cold atoms.Navigating a boat or submarine imposes constraints that are not fully met by current tools. The iXAtom joint laboratory aims to develop a solution overcoming these limitations, using cold atom quantum inertial sensors.The Quantum Day in Nouvelle-Aquitaine, organized on July 11, 2023 by the NAQUIDIS Center, was marked by the signing of the renewal of the iXAtom joint laboratory. This collaboration, which began in 2017, brings together the Laboratoire Photonique, Numérique et Nanosciences (LP2N) – associating the Institut d’Optique Graduate School, the University of Bordeaux and the CNRS – and Exail – the result of a merger between iXblue and ECA Group. The aim is to develop a new generation of inertial sensors, based on the use of cold atoms. This technological innovation could significantly improve on-board positioning and navigation systems, particularly in maritime transport. Here’s how it works.The limits of classic inertial sensors and GPSAn inertial sensor is an instrument used to measure acceleration – an accelerometer – or rotation speed – a gyrometer. These sensors are now widely used, including in our smartphones. They are also used for more critical applications, such as boat or submarine navigation, via inertial units, which combine three accelerometers and three gyrometers.“The problem is that these inertial sensors drift over time,” notes Vincent Ménoret, R&D manager at Exail and co-director of iXAtom. “For example, accelerometers are generally based on a system similar to a mass suspended from a spring, which elongates as a function of the acceleration experienced. However, these deformations also depend on a large number of external factors such as temperature or pressure…”. These variations can lead to errors, which are then amplified by the mathematical operations required to go from acceleration to position, up to several hundred meters after an hour’s travel.How can these inaccuracies be corrected, without having to recalibrate the measuring equipment? The solution often chosen is to couple inertial units to GPS systems. “However, the satellite signal is not always available, for example underwater,” points out Baptiste Battelier, research engineer at the LP2N laboratory and director of iXAtom. “And some organizations may be resistant to the idea of communicating with the outside world or depending on a GPS signal.”Cold atom quantum sensorsThe joint laboratory favors the option of an autonomous navigation system, using quantum inertial sensors. Their principle: to study cold atoms in free fall, within a vacuum enclosure. “The atom has several advantages,” explains Baptiste Battelier. “Firstly, it’s easy to manipulate with lasers, for measurement purposes. And, thanks to our in-depth knowledge of its structure and fundamental properties, we can deduce information about the acceleration it undergoes. What’s more, its free-fall behavior remains the same anywhere in the world, at any time.” Quantum sensors therefore theoretically offer absolute measurements, immune to potential drift.But what’s the point of cooling these atoms? “Cooling helps us to limit the expansion of the cloud of atoms, so as to confine it to a restricted space, where we apply our laser beam,” continues the iXAtom director. “This allows us to carry out longer measurements, and therefore achieve greater sensitivity.”Quantum-classical hybridizationAll in all, quantum inertial sensors are proving to be more accurate, sensitive and stable than their conventional counterparts. Is this enough to replace them once and for all? “Quantum sensors also have their limitations,” says Vincent Ménoret, “for example, the need to cool the atoms means that they cannot measure at certain times. Similarly, very high accelerations can exceed measurement dynamics.”The iXAtom team therefore decided to combine the two technologies, in order to compensate for the limitations of each. The first phase of the collaboration, between 2017 and 2021, thus led to the construction of a three-axis cold atom accelerometer, the fruit of a hybridization between quantum and classical inertial sensors, which could be used in maritime or air transport, but also in other fields such as the defense industry or geophysics. This research has already been the subject of five patents and four scientific publications, and has led to the hiring of a PhD student and a postdoctoral fellow by Exail. “But we don’t intend to stop there,” says Baptiste Battelier. “First of all, we realized that high turnover was making our system ineffective. So we’re working on ways to compensate for these effects. We also want our system to be able to be taken on board a boat, which means further improving our performance and continuing our engineering work to make it sufficiently compact. These are just some of the issues on which researchers will be working during this second phase, which will culminate in the signing of the joint laboratory renewal agreement.

VEGA: Development of embedded quantum gravimeters

This project aims to develop embedded quantum gravimeters (using atomic interferometry with laser-cooled atoms). The project includes both fundamental research questions and prototyping, with the final objective of designing a cold atom quantum gravimeter in a strap-down configuration (without active stabilization platform) on mobile carriers. In terms of performance, the aim is to improve performance by an order of magnitude compared to existing classical sensors, in particular in terms of accuracy. This will considerably facilitate the measurement process by eliminating the static calibration phases.To reach this goal, several technical and scientific challenges will have to be addressed:– Optimal coupling between the atomic interferometer, conventional sensors (mechanical accelerometers, fiber optic gyros), and the carrier’s navigation unit. This question of hybridization and fusion of sensors is central because quantum sensors alone will not be able to meet the constraints imposed by a dynamic environment.– To define the optimal operating regime of the atomic interferometer to guarantee a high level of performance in variable conditions (sea state, vibrations, etc.)– To understand the needs of the end-users in terms of performance, but also in terms of size and power consumption, in order to reach the optimal compromise in terms of operability.– To define the best system architecture taking into account all these constraints.The expected results are the following:– An operational prototype of an embedded quantum gravimeter running on a stabilized platform, and ready to be commercialized– Demonstration of the principle of a quantum gravimeter in strap-down configuration, and understanding of the technical and scientific limitations– New techniques allowing an optimal hybridization between quantum and classical sensors for embedded gravimetry– New technological building blocks (electronics, optics, mechanics, software) to improve the embeddability of quantum sensors, or their operation in a dynamic environment

Development of the next generation of Quantum Gravimeters

Since November 2022, NAQUIDIS and 9 European partners have launched the FIQUgS project, thanks to the Horizon Europe program. ETA: November 2025 Gravimetry aims at unveiling the density structure of the undergrounds by measuring subtle changes of the local gravity acceleration. The first-generation of quantum gravity sensors (QGs) has received a strong interest from many customers, and the market is still growing. But the commercial potential and the positive-impact of the technology are not yet fully exploited because of several limitations such as transportability, robustness, user-friendless or high operation costs. To overcome the barriers that limit the operational utilization of field gravimetry and develop the solutions that will allow us to fully address the exploitable market, we propose to conduct in FIQUgS the development of several innovations, either at the technological level with improved QGs built upon a reliable and efficient supply chain, or in terms of operational methodology. The development of a next generation QGs product line, and the services associated for the conduction of field surveys, data acquisition and data inversion will allow to considerably develop our capability to address the market of advanced geophysics. The unique industrial and technological capabilities that will result from FIQUgS will positively contribute to several important societal objectives, especially the European Green Deal: – the new field QGs will allow for a reduction of the environmental impact associated with mining activities thanks to a reduction of drilling operations, and civil engineering where it will contribute to more efficient and resilient constructions. – they will contribute to improved utilization of geothermal energies through the development of non-invasive monitoring capabilities of the energy reservoir. – they will be involved in CO2 storage operations and will contribute to the fight against global warming thanks to these advanced monitoring capabilities. FIQUgS will also have an impact on quantum technologies markets, such as high-performance navigation or advanced photonics.Some positions are available, do not hesitate to contact us!More information here.Partners: Exail, asphericon, Robotnik, GReD, widmo, BRGM, University of Liège, CNRS-SYRTE, TNO, Naquidis Center

Correlated quantum sensors to verify General Relativity

A team of French physicians (CNRS, Institut d’Optique Graduate School, Observatoire de Paris, UPMC, Université de Bordeaux), supported by CNES and ESA, publishes a detailed study showing how two different matter waves can allow to test the principle of the universality of free fall using correlated atom interferometers. Beyond this technological « tour de force », this experiment constitutes a first step to explore space-time with quantum objects. At first sight, General Relativity, the theory of gravitation predicting macroscopic phenomena, and Quantum Mechanics, describing the infinitesimally small, are irreconcilable. For example, the concept of time itself differs from one theory to another. In Quantum Mechanics, time is an independent external variable of evolution, while in general relativity time (or rather space-time) obeys its own dynamics. At the heart of this latest theory, the equivalence principle states that bodies of different masses fall at the same speed if they are subject to the same gravity field. If this principle is largely verified with objects of large size, its application to the microscopic “quantum” world still gives rise to numerous questions today. Atoms cooled at a few millionths above the absolute zero in the inertial quantum sensors could start to provide answers to these questions. To reach this goal, this team has developed an experiment allowing in a unique way to measure simultaneously the acceleration of quantum particles of different masses. 10 million atoms cooled at + 0.000001 degrees, Rubidium on one side, and Potassium, twice lighter, on the other side are sent in two simultaneous interferometers. The results are remarkable because they demonstrate that this simultaneous measurement allows to correlate two atom interferometers and reach a precision largely unsensitive to external perturbations. Thanks to a meticulous study of all the effects which could degrade the performances of the measurement, the physicians showed this is particularly important to control the relative trajectories of the particles, and the spatial characteristics of the atomic detection as well. The team doesn’t intend to stop at this first transitional result. By pushing further the technology of quantum sensors, they aim to reach a precision at which the equivalence principle will be tested at the quantum level. For this objective, much colder atoms are required to produce much more sensitive interferometers where matter waves propagate over larger distances. This measurement will go through operating these sensors in microgravity, within the simulator developed at Institut d’Optique d’Aquitaine or later aboard a satellite in orbit around the Earth. Beyond this test of a cornerstone of General Relativity, these ultimate sensors pave the way to explore the frontier between the quantum world and the relativistic world. These results are published in the journal AVS Quantum Science, in the special issue « Celebrating Roger Penrose’s Nobel prize ». Read the article.

Naquidis coordinates and submits VIQTOR, its first European project, and wins 2021 ‘Setting up European or/and International Scientific Networks (MRSEI)’ call for projects

Quantum sensors have been studied extensively and are commercially available today, but they are also very limited. Measurements can only be made along one direction, whereas three-dimensional vector-type measurements are required for many applications. In addition, ‘dead time’ during the measurements degrades the accuracy, especially over long-term use. Through close collaboration between European and Canadian research institutes, VIQTOR proposes to develop a novel 3D quantum manipulation toolbox that will lead to a new generation of vectorial quantum sensors. VIQTOR also proposes to develop a quantum sensor array with links between several spatially distributed nodes. This infrastructure will enable observations of small ‘inertial anomalies’ with improved sensitivity. The combination of these two innovations will lead to a vector map of accelerations and rotations on the geosphere – enabling the detection of small geophysical signals previously inaccessible with classical sensors. These capabilities create new market opportunities, such as positioning without GPS, resource management without drilling, or improved early-warning systems for natural disasters such as earthquakes, floods, or volcanic eruptions.

This was a way for the Gironde-based company to rapidly ramp up its operations and boost its turnover, which had topped out at around 3 million euros, as it was “limited by its size”, says Philippe Bouyer. “Joining a well-established company like iXblue”, which has over 700 employees worldwide and has also recently acquired Pessac-based photonics specialist Kylia, “will give us access to a global sales distribution network and an integrated customer base. And allow us to integrate vertically, which are two important aspects to increasing our production capabilities and growth”, says Muquans’ co-founder and chief scientific advisor.’ Read the article

XLIM and IMB among the nine finalists of NIST’s Post-Quantum Cryptography Program

Securing today’s data against tomorrow’s enemies. Digital communications are currently protected by asymmetric cryptography technology. Peter Shor has shown that a powerful quantum computer could break current encryption. What would happen if some of today’s top-secret information, such as diplomatic negotiations, financial transactions or even health data, were to be leaked in 5, 10 or even 20 years’ time? To combat this threat, cryptographers must accept that they are not fighting on an equal playing field. They must find a way to protect information from future quantum enemies with today’s classical computers. The underlying scientific challenge is to find simple mathematical operations that can be performed on everyone’s devices and which cannot be undone by an inordinate amount of computing power. One way to model these new problems is to imagine a grid and a token. It is easy to decide whether the token is close to the grid. But if now, instead of being given the grid, you are only given a few points close to it along with the token. In that case, it is much more difficult to determine whether the token is in a reasonable vicinity of the grid. At the end of 2016, the American National Institute of Standards and Technology (NIST) launched an international competition since to look for future post-quantum standards and has since received 69 valid proposals. After three selection rounds over several years, two of XLIM’s algorithms (BIKE and HQC) are among the nine finalists for the cryptography of tomorrow. The Xlim Newsletter no. 23 – December 2020
