A QUANTUM trick could pave the way for the world’s smallest fridge – one built on the atomic scale. The small but mighty cooler could brush the ultimate chill of absolute zero to keep quantum computers running smoothly, according to a team of theoretical physicists.
Blueprints for the device, designed by , and at the University of Bristol, UK, suggest that the fridge would consist of two quantum bits, or qubits, which interact with a third qubit in such a way that it would cool.
Each qubit has two possible energy states: high, or “1”, and…
