Researchers propose encoding protected qubits in cat states

Sep 14, 1998

Paul Cochrane, Gerard Milburn and William Munro propose encoding a logical qubit in a superposition of distinct oscillator states, known as a cat state. Their scheme converts spontaneous-emission errors into correctable bit flips.

Why it matters

Bosonic codes store protected quantum information in an oscillator, opening a different route to error correction from encoding it across many two-level systems.
