Connector in quantum market leads the way with cryogenic connectivity

05-12-2023 | Intelliconnect | Industrial

The new CryoCoax Q-CON high-density cryogenic connector for quantum computing from Intelliconnect (Europe) provides reliable transmission of critical signals at very low temperatures, providing compact and simple connection up to 24 ways with attenuators available to suppress thermal noise.

Craig Robinson, sales manager of Intelliconnect (Europe), recently visited the National Physics Laboratory at their new, dedicated building for Advanced Quantum Metrology to meet with Conservative MP and Minister for Science and Innovation Andrew Griffin and Gemma Chapman, Higher Scientist for Quantum at the UK National Physics Laboratory.

They discussed how cryogenic testing of the company's new high-density connector at NPL had considerably assisted the market acceptance of this innovative product for use in dilution refrigerators in the Quantum Computer sector.

These high-density multiway connectors are based around the SMPM interface to fulfil the requirements of large-scale high qubit Quantum machines and provide many more coaxial lines in a given space, simplifying the installation and customisation within a dilution refrigerator. Typical spacing using SMA connectors is limited to approximately 16mm, whereas the new high-density connectors are designed with a pitch of 4.75mm. The SMPM interface provides a simple push-to-mate connection requiring only a hex key to tighten the two fasteners.
