Huge quantum computing constraint overcome by new discovery (news).

The current quantum computers being developed by scientists can only work at fractions of a degree above absolute zero.

This requires multi-million-pound refrigeration systems, as, when you plug them into conventional electronic circuits, they instantly overheat.

But now a team led by Andrew Dzurak at the University of New South Wales has shown they can operate silicon qubits at temperatures 15 times hotter than most qubits, creating a path from experimental models to affordable computers for real world business and government applications.
