Molecular engineers at the University of Chicago have found a way to extend the quantum state of a qubit to 22 milliseconds, representing a huge improvement and a window some say will make quantum computers far more feasible. The secret is an alternating magnetic field, which they say is scientifically “intricate” but easy to apply.
Working with qubits in solid silicon carbide, the scientists extended the time in quantum state of their qubit to 22 milliseconds, which sounds small to our slow human brains, but is almost an eternity for a qubit. In fact, the researchers say it’s 10,000 times longer than the next nearest quantum state finding.
Honestly, it’s almost eternity for your regular computer, too. My not-new MacBook Pro, for example, has a 3.1 GHz processor, meaning it pushes up to 3.1 billion “beats” per second of incremental computer math. In 22 milliseconds, it would crank through 68,200,000 tiny data ticks. Quantum computing doesn’t even operate in the same paradigm, which is part of its appeal—but it’s potentially much faster, almost unfathomably so.
