As US-China tech war heats up, scientists find new material to cool quantum computers

Helium is used as a coolant for research and applications that need extreme cold, but it’s in short supply. International team says ‘supersolid’ material has potential for achieving the ultra-low temperatures needed. — SCMP

A Chinese-led team of scientists say they have found a new material that could be used to create the ultra-low temperatures needed for hi-tech applications such as quantum computing.

It could be a significant development for China, which depends on imports of helium – the coolant used for this purpose – from countries including the United States.
