How Many Qubits Do You Need? Amazon’s Shortcut to Error Correction

By Andre Saraiva, UNSW Ambitious quantum algorithms require many qubits. Many more than quantum computer manufacturers are offering currently. The most qubit-hungry applications are those that require quantum error correction, such as the notorious Shor algorithm that threatens our cryptosystems. Exactly how many qubits are needed is a complicated question. The more qubits we cram […]
