abstract = {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.},
