24 days-stable CNOT-gate on fluxonium qubits with over 99.9% fidelity
Wei-Ju Lin, Hyunheung Cho, Yinqi Chen +3
Fluxonium qubit is a promising building block for quantum information processing due to its long coherence time and strong anharmonicity. In this paper, we realize a 60 ns direct C…
Verifying the analogy between transversely coupled spin-1/2 systems and inductively-coupled fluxoniums
Wei-Ju Lin, Hyunheung Cho, Yinqi Chen +3
We report a detailed characterization of two inductively coupled superconducting fluxonium qubits for implementing high-fidelity cross-resonance gates. Our circuit stands out becau…
Voltage Activated Parametric Entangling Gates on Gatemons
Yinqi Chen, Konstantin N. Nesterov, Hugh Churchill +3
We describe the generation of entangling gates on superconductor-semiconductor hybrid qubits by ac voltage modulation of the Josephson energy. Our numerical simulations demonstrate…
Fast Flux Entangling Gate for Fluxonium Circuits
Yinqi Chen, Konstantin N. Nesterov, Vladimir E. Manucharyan +1
We analyze a high-fidelity two-qubit gate using fast flux pulses on superconducting fluxonium qubits. The gate is realized by temporarily detuning magnetic flux through fluxonium l…
