Systematic frequency-collision analysis of the cross-resonance gate outside the straddling regime
Shinichi Inoue, Shotaro Shirai, Shuhei Tamate +4
Frequency crowding remains a major obstacle to scaling fixed-frequency transmon processors. Among the widely used all-microwave two-qubit gates, the cross-resonance (CR) gate is pa…
Flux-Trapping Fluxonium Qubit
Kotaro Hida, Kohei Matsuura, Shu Watanabe +1
In pursuit of superconducting quantum computing, fluxonium qubits have recently garnered attention for their large anharmonicity and high coherence at the sweet spot. Towards the l…
Non-demolition fluorescence readout and high-fidelity unconditional reset of a fluxonium qubit via dissipation engineering
Shu Watanabe, Kotaro Hida, Kohei Matsuura +1
Non-demolition readout and high-fidelity unconditional reset of qubits are key requirements for practical quantum computation. For superconducting qubits, readout and reset are typ…
ZZ-Interaction-Free Single-Qubit-Gate Optimization in Superconducting Qubits
Shu Watanabe, Yutaka Tabuchi, Kentaro Heya +2
Overcoming the issue of qubit-frequency fluctuations is essential to realize stable and practical quantum computing with solid-state qubits. Static ZZ interaction, which causes a f…
