Applications

Due to our capability to provide a high level of customization, our dilution refrigerators are used for a wide range of applications, such as bolometry, condensed matter experiments or quantum computing.

Quantum computing

Quantum computing could be the next breakthrough in computer science. Instead of using bits that can only take values 0 or 1, quantum computers use the superposition principle of quantum objects to operate with qubits (quantum bits) that can take values 0 and 1 simultaneously, thus promising to solve problems intractable even for the world’s largest supercomputers.

Different technologies can be used to create quantum computers, and most of them (Josephson, CMOS etc…) involve very low temperatures below 1K. In that case dilution refrigerators are used to keep Qubits cool. Qubits and their associated electronics are space-hungy, to satisfy this need our HEXA-DRY product range has been developed with a compact design in order to optimize the space available for the experiment.

As the architecture of quantum computers can be very diverse our systems are highly customizable to fit all designs. If needed, our Dilution Refrigerator can at any time be upgraded to a low-vibration mode thanks to our Ultra-Quiet Technology (UQT).

Quantum computers aim to have a larger number of Qubits in the coming years, classical dilution refrigerators could not fit to this new need. In order to take quantum computing from laboratory to industrial scale we are developing with Air Liquide disruptive technologies to create larger dilution refrigerators able to handle thousands of qubits and more with a high reliability.


Bolometry


Bolometers are detectors whose principle is to convert the energy of incident radiation into heat to raise the temperature of a body equipped with a thermometer.

Bolometry gathers a large number of characteristics to ensure the good functioning of the experiment in a dilution refrigerator.

In particular, a low vibration level has proven to be key for bolometers measurement.

Our proprietary Ultra Quiet Technology™ proved that by offering the lowest level of vibration on the market in continuous operation, we can significantly increase the quality of the measurement.

In addition, bolometers are highly sensitive to radiation. To avoid any contamination of the measurement on our systems, we use archaeological copper and lead. Both materials are necessary for the manufacturing of the Outer Vaccum Chamber (OVC), the lead shield assembly and the shields.

In order to gather all these specific requirements we have developed the dilution refrigerator HEXA-DRY Bolometry (UQT). It was designed to work during the long run (more than 1 year) while being controlled in a fully-remote mode. Today we appear as a leader in this segment of the cryogenic market thanks to our expertise and our extreme low level of vibration in bolometry experiments.

Condensed matter


Condensed matter physics is one of the most active fields of contemporary physics because of the diversity of systems and phenomena available for study.

Condensed matter studies systems with many constituents that have strong interactions between them. Low temperature and high magnetic fields are typically used to reveal astonishing properties of matter as the fractional quantum Hall effect.

To address the specific needs of those applications, we have designed our systems to have magnets parallel with the dilution unit, thus allowing the system to be very compact with a low cool-down time. For those experiments, using our Ultra Quiet Technology™ also enables a good thermalization of electrons by limiting tribo-electricity generated in coaxial cables.
