Physicists continue to argue over Microsoft’s qubit claims. The entire field hangs in a delicate balance.

Quantum computing could make it easier to process massive amounts of information in the near future. Unlike traditional computers, which still store data in binary bits of zeros and ones, quantum computers can store them simultaneously in qubits.

Shares in major quantum computing firms dropped on Thursday after an announcement from Nvidia chief Jensen Huang. It’s not the first time. Quantum computing stocks got pummeled yesterday, with the four most prominent public quantum computing companies—IonQ,
