IBM’s project Goldeneye has advanced in low-temperature refrigeration with its super-fridge that can chill things cooler than outer space and this lays the groundwork to scale up bigger experiments, for the ability of quantum industry

Quantum computing is advancing field and it needs significantly cold temperatures. Now IBM researchers have developed and demonstrated a large super-fridge, which is dubbed Project Goldeneye that can chill things colder than outer space. This development lays the base for scaling up larger experiments for quantum industry.

Quantum computers are known for their superfast speed as well as power, which they get from quantum physics realm. These computers can process huge amounts of data simultaneously while teleporting information. However, these computers can be highly sensitive to environmental interference like heat due to which, they are kept at cryogenic temperatures. Now IBM have developed a new proof-of-concept cooling system, which is called as dilution refrigerator. It uses a combination of helium-3 and -4 for cooling contents to the mK (milli-Kelvin) range. The Goldeneye consists experimental 1.7 m3 volume, which apparently is 2 to 3 times greater than earlier ones. This system is modular and contains clamshell design allowing the sideways opening of outer vacuum chamber in order for researchers to access the hardware inside with ease.

When the researchers tested the Goldeneye, they observed that it is capable of cooling down to only 25mK, and it is 1,000x cooler than normal space temperature. The researcher placed a quantum chip in it to cool it, where they achieved a 450 microseconds of coherence time, which is the time quibits retain information. This development as per the company is equivalent of pre-existing dilution fridge systems.

The Goldeneye system must sound promising however; it may not be utilized to cool quantum computers in its current form, as reported by IBM. Nevertheless, the tested concepts are to be used as base for next generation cooling systems.
