Making quantum error correction more practical

Quantum computers are inherently noisy, and quantum error correction is essential if we’re going to achieve fault-tolerant machines. With additional quantum bits (or qubits), we can detect and correct errors, curtail their spread in circuits, and enable complex, long and accurate computations. Research into quantum error correction has been underway for over two decades, but only recently has quantum hardware matured to the point where we can have practical demonstrations of several different components of quantum error correction. In this …
