Lincoln Laboratory: Ribbon Cables Enable Power & Data in 5–10 Millikelvin Ranges

Researchers at MIT Lincoln Laboratory have prototyped flexible cryogenic cables capable of operating within the extremely narrow temperature range of 5 to 10 millikelvin, colder than the temperatures encountered in space, a crucial advancement for stabilizing qubits and minimizing thermal noise in quantum computing research. These ribbon-like cables address a key challenge in building dilution refrigerators, the specialized equipment needed to create the ultra-cold environments essential for quantum systems, by simultaneously supporting high-speed data transmission and direct current power. Maybell Quantum, a Colorado-based company supplying hardware for quantum systems, has licensed the design and plans to integrate the wiring, dubbed LF…
