High fidelity fermionic simulation gates with superconducting gmon qubits

ORAL

Abstract

We present an experimental realization of a high-fidelity 2-qubit continuous fermionic simulation (fSim) gateset using superconducting gmon qubits. Each fSim gate is parameterized by two angles: the |01> to |10> swap angle θ, and the conditional phase angle φ. The full fSim(θ, φ) gateset covering θ: [0°, 90°] and φ: [-180°, 180°] includes both the iSwap (fSim(90°, 0°)) and controlled-Z (fSim(0°, 180°)) gates making it applicable to error correction, quantum supremacy, and pre-error correction applications including quantum chemistry and quantum approximate optimization algorithms.
