New flexible cryogenic cable design stays pliable below 20 mK for quantum systems

MIT Lincoln Laboratory developed flexible cryogenic cables that stay pliable below 20 mK.

The new design aims to reduce thermal leakage and improve wiring reliability inside dilution refrigerators.

That matters for quantum computers, which need dense cabling that adds little heat and survives repeated cooling cycles.

If successful, the approach could make large-scale qubit control hardware easier to build and operate.
