Building quantum computers underground or designing radiation-proof qubits may be needed, researchers find.
The practicality of quantum computing hangs on the integrity of the quantum bit, or qubit.
Qubits, the logic elements of quantum computers, are coherent two-level systems that represent quantum information. Each qubit has the strange ability…
