The Second Quantum Revolution is unfolding now, exploiting the enormous advancements in our ability to detect and manipulate individual quantum objects (photons, atoms, ions, …). In particular, the groundbreaking experiments using entangled quantum states, awarded with the 2022 physics Nobel Prize, have cleared the way for new technology based upon quantum information.

iXblue Quantum Sensors division (formerly Muquans), founded in 2011 in the very footsteps of Alain Aspect by 3 of his former students, is the world’s first company to commercialize industry-grade quantum sensors based on laser cooled atoms. Such sensors are now operated worldwide by non specialist, from the top of Mount Etna to Antarctica.

iXblue’s Portfolio for Quantum Technologies

Beyond Quantum Sensing, other remarkable technology developments enable mature applications in Quantum Communication, Quantum Simulation and Quantum Computing in public laboratories and in the industry. Should you rely on photons, neutral atoms, trapped ions, NV-centers to implement Quantum Technologies, our expertise and products will help reaching the most ambitious goals.

Here is an example of setup for the manipulation of quantum systems using iXblue’s components, sub-systems and fully integrated systems:

Photonics solutions for Quantum Sensing, Quantum Communication, Quantum Computing and Quantum Simulation

A flagship instrument for Quantum Sensing

iXblue’s Absolute Quantum Gravimeters are now operated worldwide by non-specialists, from the top of Mount Etna to Antarctica. They rely on atom interferometry with laser-cooled Rubidium atom and feature a state-of-the-art measurement performance at the level of 10-8 m/s² stable over years.

iXblue’s developments now benefit the area of Quantum Sensing: turn-key metrology-grade laser systems, integrated micro-optics benches (iMOBs) and modulation solutions are commercially available to precisely control and convey the frequency, phase and amplitude of laser light regardless of the environment.

Quantum Communication

A key topic of Quantum Technologies regards the ability to share quantum information between distinct parties – either locally or at distance – for which iXblue’s photonics solution provide strong technological advange. For long-distance Quantum Communication, Quantum Repeaters are being developed with iXblue’s Intelligent Laser Systems (ILS) and integrated Micro-optical Benches (iMOB) for reliable field-compatible entanglement distribution.

One of the main current applications today is Quantum Key Distribution (QKD) and iXblue has become a key player for Continuous-Variable QKD (CV-QKD), but also for Discrete-Variable QKD (DV-QKD). Our modulation solutions with matching components for the transmitter side of the communication (Alice) and COH 90° optical hybrids demodulators enable to extract phase, amplitude and polarization on the receiver side (Bob).

Towards Quantum Inertial Navigation

iXblue’s R&D teams nurture fruitful collaborations with leading research labs. The iXAtom joint laboratory brings together iXblue and researchers from the Laboratoire Photonique Numérique et Nanosciences – LP2N lab (CNRS / Institut d’Optique Graduate School / Université de Bordeaux) to develop quantum technologies for high end Inertial Sensors.

The iXAtom research team has realized the first 3-axis quantum inertial sensor that allows to measure continuously the acceleration in 3 dimensions and for any orientation of the sensor. This is an important step towards the realization of an inertial navigation system using quantum technologies, and it leverages all of our state-of-the-art photonics solutions.

The 3-axis quantum inertial sensor developed by iXAtom joint laboratory is perfectly suited to on-board operation and may, in the future, overcome the need for current navigation systems to recalibrate frequently with an external device signal such as GNSS.
