Realizing high fidelity entanglement gates is a major task for near-term quantum hardware. Withhigher fidelity gates achieved in experiments, more accurate theoretical methods are needed. Here,using non-perturbative formalism, we theoretically study an iSWAP gate activated by frequencymodulation in a transmon-transmon pair. We make a comprehensive analysis to directly solving thetime-dependency and introduce a continuous set of Fermionic Simulation gates by tuning qubit-qubitdetuning and pulse phase.Conventional Josephson junction-based qubits are promising candidates for practical quantumprocessors. Although high-quality qubits and high-fidelity gates have been routinely fabricated, qubitcoherence time is hindered by several material-based artefacts and losses, such as defects in Josephsonjunctions due to the fabrication procedure. Recently nanowire qubits have shown a possible candidatefor unconventional junction. They serve as weakly anharmonic inductors without interface defects. T1and T2 of microsecond order have been observed. We study the problem theoreticall and try totheoretically analyze the current-phase relation, anharmonicity, and coherence times in nanowirequbits. This paves the way to study nanowire qubits in circuit-QED setup further. |
