The technique involves spraying electrons from a light bulbs filament, according to arecent paperin the peer-reviewed journalNature.

Better Bits

Quantum computers hold the promise of revolutionizing computing.

The Argonne team focused on using a single electron as a qubit.

Companies including IBMand Google have existing systems with up to 100 qubits of processing power.

But, he added, challenges remain to make the process small enough to fit into everyday computers.
