Just 10,000 quantum bits might crack internet encryption schemes

Computers based on atoms could demand a fraction of the qubits previously estimated

Error correction schemes make reliable logical qubits (gold) from error-prone physical qubits (blue). A new scheme produces many more logical qubits per physical qubit (right) than traditional methods (left).
