A slightly smaller surface code S gate
Craig Gidney, Austin Fowler
TL;DR
This paper presents a modification to the surface code S gate that reduces its volume by 25% by removing a Hadamard gate, potentially improving quantum error correction efficiency.
Contribution
The authors propose a simplified surface code S gate implementation that omits a Hadamard gate, reducing resource requirements.
Findings
Surface code S gate volume reduced by 25%
Omission of Hadamard gate maintains functionality
Potential for more efficient quantum error correction
Abstract
We cut the volume of surface code S gates by 25% by omitting a Hadamard gate.
