Qubits differ from classical bits, which are coded as only 0 or 1. A qubit can be a combination of both 0 and 1 simultaneously. One way to think of it is as a coin spinning between a 0 and a 1 axis.

Princeton engineers have built a superconducting qubit that lasts three times longer than today’s best versions, marking a ...
