Proposal for erasure conversion in integer fluxonium qubits
Jiakai Wang, Raymond A. Mencia, Vladimir E. Manucharyan +1
We propose an erasure conversion scheme on the and qubits in integer fluxonium qubits (IFQs), which are both first-order insensitive to…
Anharmonicity and Charge-Noise Sensitivity of Fraunhofer Qubit
Longyu Ma, Tony Liu, Javad Shabani +3
We present a theory of a flux-tunable superconducting qubit, the "Fraunhofer qubit," based on the Fraunhofer interference in a wide ballistic Josephson junction. As magnetic flux t…
CNOT gates in inductively coupled multi-fluxonium systems
Valeria Díaz Moreno, Nikola D. Dimitrov, Vladimir E. Manucharyan +1
High-fidelity two-qubit gates have been demonstrated in systems of two fluxonium qubits; however, the realization of scalable quantum processors requires maintaining low error rate…
Cross-Resonant Gates in Hybrid Fluxonium-Transmon Systems
Nikola D. Dimitrov, Chen Wang, Vladimir E. Manucharyan +1
We propose a scalable fluxonium-transmon-fluxonium (FTF) system that utilizes a central transmon to mediate high-fidelity gates and parity checks between two fluxonium qubits witho…
Strongly anharmonic flux-tunable transmon based on InAs-Al 2D heterostructure
Shukai Liu, Arunav Bordoloi, Jacob Issokson +4
The gatemon qubits, made of transparent superconducting-semiconducting Josephson junctions, typically have even weaker anharmonicity than the opaque AlOx-junction transmons. Howeve…
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…
Integer Fluxonium Qubit
Raymond A. Mencia, Wei-Ju Lin, Hyunheung Cho +2
We describe a superconducting qubit derived from operating a properly designed fluxonium circuit in a zero magnetic field. The qubit has a frequency of about 4 GHz and an energy re…
Response of a quantum disordered spin system to a local periodic drive
A. Barış Özgüler, Canran Xu, Maxim G. Vavilov
We consider a one-dimensional spin chain system with quenched disorder and in the presence of a local periodic drive. We study the time evolution of the system in the Floquet basis…
