Silicon Chip Quantum Computing That Has Practical Cooling Costs

•, by Brian Wang

Most current quantum computers need multi-million-dollar refrigeration and as soon as you plug them into conventional electronic circuits they'll instantly overheat.

Professor Andrew Dzurak and his team at UNSW Sydney have a proof-of-concept silicon chip that works at 1.5 Kelvin. This is 15 times warmer than the main competing chip-based technology being developed by Google, IBM, and others, which uses superconducting qubits.

It needs a few thousand dollars' worth of refrigeration, rather than the millions of dollars needed to cool chips to 0.1 Kelvin.
