Quantum

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).

The efforts deployed worldwide by academic laboratories and companies to develop Quantum Processors are tremendous. For every stakeholder, from fundamental research to commercially available machines, state-of-theart reliable photonics components and systems ensure faster development. It also enables to develop and run more and more complex set-ups.

The main physical platforms involved (neutral atoms, photons, ions…) can rely on iXblue’s photonics solutions iMOBs and modulation solutions.

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.

Leveraging 30 years of advanced expertise in Fiber-Optic Gyroscopes, operating from deep ocean to outer space, and 10 years in delivering Quantum Gravimeter from Mount Etna to Antarctica, iXblue’s photonics solutions are able to operate under extreme conditions: they are resistant to external disruptions such as shocks, extreme temperatures, magnetism and vibrations.

iXblue and its Quantum Sensors division (ex-Muquans) is the world’s first company to commercialize industry-grade quantum sensors based on laser cooled atoms, including: the world most accurate atomic clock on the market, the Muclock, the first world quantum gravimeter having performed the detection of gravity changes induced by volcanic processes, on top of Mount Etna.

The development of dedicated intelligent frequency-stabilized laser systems and Integrated micro-optics benches holds the key to such success. This state-of-the-art range of technologies are the results of iXblue’s capability to select the adapted sub-components and to integrate them into turn-key instruments, now operated worldwide by non specialists.

The laser systems developed by iXblue for atom manipulation and atom cooling/trapping are now available for a broad range of users, including non specialists.

Using such mature lasers for your experiments in quantum technology is a time saver. Some of the most promising innovative companies in the field are already using them, including Pasqal and Welinq.

iXblue expertise in the manufacturing of integrated micro-optics benches lies on the ultra-accurate assembly of optical elements on glass breadboards, using 6D positioning. Thanks to its know-how in assembly epoxies, initially developed for the telecom industry, it can provide stable and robust devices, built to be used in extreme environment.

Joint laboratories are partnership research collaborations built between iXblue and academic laboratories around a shared scientific theme. They respond to both the needs of ambitious research and long-term industrial challenges. They offer a structural, flexible, and enduring framework, allowing to leverage on the complementary strengths of both partners and allowing potential technological breakthroughs.
