Physicists at Caltech have taken a major step toward the future of computing by creating the world’s largest array of quantum bits, or qubits.

The new setup contains 6,100 neutral-atom qubits, nearly ten times more than what was previously possible, marking a milestone in the global race to build powerful quantum computers.

Quantum computers differ from classical ones because their basic units of information, qubits, can exist in two states at once. This property, called superposition, allows quantum machines to perform certain calculations much faster than ordinary computers.

But qubits are extremely fragile, and to make reliable machines, scientists must use thousands or even hundreds of thousands of them with error-correcting systems.
