IBM reveals plans for 'quantum fridges' — its next-gen cooling hardware, which could be the key to quantum computers finally reaching their potential
- IBM connects two box-shaped cryogenic modules into a single environment and cooled them below 15 millikelvin, linked by a thermally shielded tunnel carrying quantum cables between cells
- The cooling technology is established dilution refrigeration; what is new is an enclosure that offers up to twelve times more wiring area and lets modules sit side by side with shorter interconnects in tow
- IBM plans to install Nighthawk chips later this year, with a roadmap targeting 1,000 programmable qubits by 2027 and establishing fault tolerance in 2029
IBM has joined two cryogenic modules into a single environment at its Poughkeepsie facility and cooled the combined system to below 15 millikelvin, bringing it as close to absolute zero as possible.
The company said this was an important milestone on the road to IBM Quantum Starling, the fault-tolerant machine it intends to deliver in 2029.
IBM said the temperature is more than 180 times...
