A superconducting microwave resonator (gold curves) can use microwaves (pale beam) to help control a single isolated electron (orange waves) trapped on a block of solid frozen neon (green block).

Researchers led by the U.S. Department of Energy's Argonne National Laboratory created a new quantum bit (qubit) platform using frozen neon gas.

The platform sprays electrons from a light bulb's filament onto the solidified neon, which traps a single electron.

The apparatus incorporates a chip-scale microwave resonator fashioned from a superconductor, which "crucially provides a way to read out the state of the qubit," according to Washington University in St. Louis' Kater Murch.

"It concentrates the interaction between the qubit and microwave signal. This allows us to make measurements telling how well the qubit works."
