Gottesman, Kitaev and Preskill propose protecting a qubit inside an oscillator

Aug 8, 2000

Daniel Gottesman, Alexei Kitaev and John Preskill propose error-correcting codes that store a qubit in an oscillator, a system with continuously varying quantum properties. The codes protect against small shifts in those properties.

Why it matters

The proposal gives bosonic quantum computing a way to protect information within a single oscillator, using its many available states as redundancy.
