IBM cools quantum modules to 15 millikelvin — 200 times colder than outer space

IBM has linked two cryogenic modules and cooled them to below 15 millikelvin — approximately 200 times colder than outer space. The infrastructure is intended to underpin the company's Starling quantum computing system, planned for launch in 2029. The achievement marks a significant step in developing quantum computers that require extremely low temperatures to operate.
