How can we navigate airliners or allow military vehicles to stay on course without GPS or satellite signals? This is a problem for which quantum inertial sensors offer a solution. Harnessing quantum technology, they can take ultrasensitive measurements of acceleration in three dimensions, and in any orientation.

By coupling a tensile machine and an in situ dielectric measurement, physicists from Lyon (ENS de Lyon Physicis Laboratory and MATEIS) have made a breakthrough in understanding the molecular reorganizations that allow a polymer film to stretch. The results of this study are published in the journal Macromolecules .

The James Webb telescope has delivered extraordinary new images of the Orion Nebula. Many stars are born in this nebula, hence these observations could yield information on the origins of our Solar system. The new images were obtained by a team headed by French and Canadian researchers. An international research team has released the first images of the Orion Nebula, the closest richly productive stellar nursery to our own solar system.

Chromosomes are fluid - almost liquid - outside their division phases. This discovery was made possible thanks to the direct mechanical manipulation, for the very first time, of chromosomes in the nucleus of living cells. Until then, chromosomes - which are very long DNA molecules - were represented as being entangled like loose balls of yarn, and forming a sort of gel.

Constructing a tiny robot from DNA and using it to study cell processes invisible to the naked eye. You would be forgiven for thinking it is science fiction, but it is in fact the subject of serious research by scientists from Inserm, CNRS and Université de Montpellier at the Structural Biology Center in Montpellier .

SAN FRANCISCO - Dec. CEA, in collaboration with CNRS Néel, a leading team in SI-based quantum c'omputing, presented two papers on that topic at IEDM 2021, including an invited paper that identifies the material and integration challenges facing large-scale Si quantum computing. The second paper presents a novel Si quantum device integration that reduces by half the effective gate pitch and provides full controllability in 1D FD-SOI quantum dot (QD) arrays.

Einstein's theory of gravity, general relativity, has not been disproven once in over a century, despite relentless efforts from scientists to find its faults. Pulsars are stars toward the end of the stellar life cycle, emitting radio waves that sweep through space like a lighthouse: they can be detected by radio telescopes in the form of highly regular flashes.

CRAL publication in MNRAS , on September 16, 2021. CNRS press release on September 16, 2021. Galaxies can receive and exchange matter with their external environment thanks to the galactic winds created by stellar explosions. Thanks to the MUSE instrument  from the Very Large Telescope at the ESO, an international research team, led on the French side by the CNRS and l'Université Claude Bernard Lyon 1 , has mapped a galactic wind for the first time.

Artificial intelligence surpasses the human brain only at the cost of consuming tens of thousands of times more energy. A major difference between the brain and electronic systems is that neurons use ions, not electrons, to carry information. French scientists have designed theoretical artificial neurons with ions to carry the information.

Quantum information could be behind the next technological revolution. By analogy with the bit in classical computing, the qubit is the basic element of quantum computing. However, demonstrating the existence of this information storage unit and using it remains complex, and hence limited.

Gravitational wave detectors have observed a new type of cataclysmic event in the cosmos: the merger of a neutron star with a black hole. The phenomenon was detected twice in January 2020. Several hypotheses could explain the existence of such mixed pairs. Further observations will be needed in order to settle the question.

Studying how liquid foams evolve over time is difficult, if not impossible, on Earth because of gravity. The FOAM-C experiment, which began in 2020, was designed to study liquid foams in zero gravity on board the ISS. New samples will be set up by French astronaut Thomas Pesquet on Friday, June 11. The FOAM-C experiment studies the properties of liquid foams in zero gravity.

Muons, particles akin to electrons, have kept physicists' heads spinning for more than a decade, because an experimental measurement of their magnetic properties 1 disagrees from theory. Could this be caused by unknown particles or forces? A new theoretical calculation of this parameter, involving CNRS physicists and published , has reduced the discrepancy with the experimental measurement.

Within the EHT collaboration, the CNRS and IRAM participated in the creation of a new image of the black hole in the M87 galaxy. Produced in so-called "polarized" light, this image makes it possible to observe the magnetic field and to better understand the physics around black holes. The Event Horizon Telescope (EHT) collaboration, who produced the first ever image of a black hole , has revealed today a new view of the massive object at the centre of the M87 galaxy: how it looks in polarised light.

The MUSE instrument on the Very Large Telescope has captured an image of several filaments in the early Universe.. .. revealing the unexpected presence of billions of dwarf galaxies in the filaments Although the filaments of gas in which galaxies are born have long been predicted by cosmological models, we have so far had no real images of such objects.

From Microscopic Holograms to New Optical Concepts and Design, the Institute Unveils Key Results Towards Integrated Retinal-Projection Displays -GRENOBLE, France - March 11, 2021 - Expanding on its previous advances in integrated optics and silicon photonics, CEA-Leti presented four related papers at Photonics West 2021 Digital Forum that show key steps toward improved AR capabilities with retinal projection.

Follow along live as the Perseverance rover lands on Mars, thanks to the SuperCam instrument on board which was co-developed by three research laboratories under the supervision of Sorbonne University. On Thursday, February 18, 2021, a little before 10:00 pm, the Perseverance rover will descend on Mars at more than 21,000 km/h.

A + A Is a quantum machine really more efficient than a conventional machine for performing calculations? Demonstrating this 'advantage' experimentally is particularly complex and a major research challenge around the world 1. Scientists from the CNRS 2 , the University of Edinburgh (Scotland) and the QC Ware, Corp., (France and USA) have just proved that a quantum machine can perform a given verification task in seconds when the same exercise would take a time equivalent to the age of the universe for a conventional computer.

GRENOBLE, France - Feb. CEA-Leti scientists have opened a pathway to large-scale integration of Si-spin qubits using existing flip-chip processes with die-to-wafer 3D-interconnect technologies developed in-house. In a paper presented during the 2020 Electronics System-Integration Technology Conference (ESTC), the team reported preliminary electrical characterizations at cryogenic temperatures of chip assemblies made with 3D interconnects such as SnAg microbumps and direct Cu bonded pads from Cu/SiO 2 hybrid bonding process.
