IBM has connected and cooled two modular cryogenic systems into a single environment for the first time, at its lab in Yorktown Heights, New York. The box-shaped modules stand more than 8 feet tall and 8 feet wide combined, reach 4 Kelvin in under five days, and settle below 15 millikelvin. It is a step toward Starling, the fault-tolerant quantum computer IBM plans to deliver in 2029.
IBM just bolted two giant fridges together, and it is one of the bigger steps yet toward a quantum computer that actually works reliably.
At its lab in Yorktown Heights, New York, IBM connected and cooled two modular cryogenic systems into a single environment for the first time.
Together they stand more than eight feet tall and eight feet wide.
They chilled down to 4 Kelvin, the temperature of liquid helium, in under five days. Then they dropped below 15 millikelvin.
IBM says that it is over 180 times colder than deep space.
Now here is why the shape matters. Quantum fridges have…
