Over the BBC, James Morgan writes that researchers have overcome a key barrier to ultrafast computers with a breakthrough that enabled fragile quantum memory state to be held stable at room temperature for a “world record” 39 minutes.
39 minutes may not seem very long. But these lifetimes are many times longer than previous experiments,” said Stephanie Simmons from Oxford University. “This opens the possibility of truly long-term storage of quantum information at room temperature,” said Prof Mike Thewalt, whose achievement is detailed in the journal Science.
To run calculations on future quantum computers, physicists will need to place different qubits in different states and control how they couple and interact. And while there are still many barriers to overcome, this particular silicon-based development could impact the future of computing in a number of ways.
