A breakthrough cooling technology could help invigorate quantum computing and slash costly preparation time in key scientific experiments by weeks.
The researchers published the details of their new machine April 23 in the journal Nature Communications. They claimed using it could save 27 million watts of power per year and reduce global energy consumption by $30 million.

PTRs use helium gas in a similar process but with far better absorption of heat and no moving parts.
The team found that by adjusting the design of the PTR between the compressor and the refrigerator, helium was used more efficiently. While cooling down, some of it is normally pushed into a relief valve rather than being pushed around the circuit as intended. The researchers said in their study that the new method could shave at least a week off experiments at the Cryogenic Underground Observatory for Rare Events — a facility in Italy that’s used to look for rare events such as a currently theoretical form of radioactive decay. As little background noise as possible must be achieved to obtain accurate results from these facilities.
