Low-overhead surface code logical H    [PDF]

Austin G. Fowler

We present an improved low-overhead implementation of surface code logical H.
We describe in full detail logical H applied to a single distance 7
double-defect logical qubit in an otherwise idle scalable array such qubits.
Our goal is to provide a clear description of logical H and to emphasize that
the surface code possesses low-overhead implementations of the entire Clifford
group.
