Non-Markovian Relaxation Spectroscopy of Fluxonium Qubits
Ze-Tong Zhuang, Dario Rosenstock, Bao-Jie Liu +3
Recent studies have shown that parasitic two-level systems (TLS) in superconducting qubits, which are a leading source of decoherence, can have relaxation times longer than the qub…
Quantum Computer Controlled by Superconducting Digital Electronics at Millikelvin Temperature
Caleb Jordan, Jacob Bernhardt, Joseph Rahamim +16
Current superconducting quantum computing platforms face significant scaling challenges, as individual signal lines are required for control of each qubit. This wiring overhead is…
Fluxonium Qubits in a Flip-Chip Package
Aaron Somoroff, Patrick Truitt, Adam Weis +10
The strong anharmonicity and high coherence times inherent to fluxonium superconducting circuits are beneficial for quantum information processing. In addition to requiring high-qu…
Demonstration of the Two-Fluxonium Cross-Resonance Gate
Ebru Dogan, Dario Rosenstock, Loïck Le Guevel +7
The superconducting fluxonium qubit has a great potential for high-fidelity quantum gates with its long coherence times and strong anharmonicity at the half flux quantum sweet spot…
Millisecond coherence in a superconducting qubit
Aaron Somoroff, Quentin Ficheux, Raymond A. Mencia +3
Increasing the degree of control over physical qubits is a crucial component of quantum computing research. We report a superconducting qubit of fluxonium type with the Ramsey cohe…
Arbitrary controlled-phase gate on fluxonium qubits using differential ac-Stark shifts
Haonan Xiong, Quentin Ficheux, Aaron Somoroff +7
Large scale quantum computing motivates the invention of two-qubit gate schemes that not only maximize the gate fidelity but also draw minimal resources. In the case of superconduc…
