One of the key challenges with quantum computing is the need to keep the qubits to near absolute zero temperature. This is a major hurdle and makes the tech expensive.
Recent independent experiments from University of New South Wales (AU) and Intel / Delft University of Technology (NL) have shown that silicon based qubits can work at higher temperatures.
This could cut the cost/size of quantum computers by allowing the use of more traditional cooling technologies, bringing real world business and government applications closer.
These are just proofs of concept but the race is surely heating up!Pun intended :-)

"Our new results open a path from experimental devices to affordable quantum computers for real world business and government applications," says Professor Dzurak at UNSW Sydney.
