Using universal fast geometric quantum gates in a superconducting circuit
Updated
Abstract
The average fidelity for single-qubit rotation gates reached 0.9977.
- A universal nonadiabatic geometric quantum gate set was realized in a superconducting qubit chain.
- Single-qubit rotation gates showed an average fidelity of 0.9977(1), while two-qubit controlled-Z gates had a fidelity of 0.977(9).
- The study compared the performance of single-qubit geometric gates with conventional dynamical gates under various control errors.
- This work may offer a method for achieving high-fidelity gates that could enhance quantum computing reliability.
