Yale corrects errors in a qubit encoded as oscillator grid states

Jul 29, 2019

Yale researchers implement error correction for a qubit stored in grid states of a superconducting cavity. Measurements detect errors while preserving the encoded information, enabling feedback to suppress different kinds of logical error.

Why it matters

The experiment puts the GKP encoding into practice as an alternative to spreading a logical qubit across many separate physical qubits.
