Quantum memory states are notorious for being restless, but scientists have managed to smash the world record and hold a quantum state stable for 39 minutes – at room temperature.
The qubits – “quantum bits” of information – stayed in a stable state for 39 minutes, lasting for almost 100 times longer than any previous record. This is a massive step in the right direction towards quantum computing – harnessing quantum mechanics to process data at impossible speeds. Once we can hold qubits in a stable state for long periods of time at room temperature, it’s then possible to look at manipulating them in order to store and process data.
This new record was set by an international team, led by Mike Thewatt at Simon Fraser University in Canada. The previous best was 25 seconds at room temperature – or 3 minutes under cryogenic (really cold) conditions.
