compact, rack mountable cryostat system

most compact full 2.3 K cryostat on the market

integration of cooled quantum devices in 19” rack systems

air-cooled, low heat generation (1kW), single phase

autonomous from special infrastructure

fully automated cooldown & operation

user-friendly push button solution

The attoCMC is the most compact cryostat system on the market operating below 5 K, with a base temperature down to below 2.3 K. It combines the new IGLU compressor technology with a high-performance cryostat and is independent from heavy laboratory infrastructure, thus revolutionizing the emerging market for quantum information processing.

It can be rack-mounted in basically any environment with minimal space and power requirements. Therefore, it provides the ideal platform for all applications that require cryogenically cooled sensorics like SNPSDs or quantum devices such as single photon sources. 

This takes quantum applications out of the lab and into the field, where first demonstrators are already set up to enable quantum secure communication networks, as well as ultra-compact quantum computers, e.g. based on cold ion trapping, or photonic qubits in semiconductors.
