Operation of a high-frequency, phase-slip qubit
Cheeranjeev Purmessur, Kaicheung Chow, Bernard van Heck +1
Aluminum-based Josephson junctions are currently the main sources of nonlinearity for control and manipulation of superconducting qubits. A constriction-based junction provides an…
Parametrically-controlled microwave-photonic interface for the fluxonium
Ke Nie, Aayam Bista, Kaicheung Chow +2
Converting quantum information from stationary qubits to traveling photons enables both fast qubit initialization and efficient generation of flying qubits for redistribution of qu…
Characterization of two fast-turnaround dry dilution refrigerators for scanning probe microscopy
Mark E. Barber, Yifan Li, Jared Gibson +13
Low-temperature scanning probe microscopes (SPMs) are critical for the study of quantum materials and quantum information science. Due to the rising costs of helium, cryogen-free c…
The Floquet Fluxonium Molecule: Driving Down Dephasing in Coupled Superconducting Qubits
Matthew Thibodeau, Angela Kou, Bryan K. Clark
High-coherence qubits, which can store and manipulate quantum states for long times with low error rates, are necessary building blocks for quantum computers. Here we propose a dri…
Signatures of Parafermion Zero Modes in Fractional Quantum Hall-Superconductor Heterostructures
Junyi Cao, Angela Kou, Eduardo Fradkin
Parafermion zero modes can arise in hybrid structures composed of fractional quantum Hall edges proximitized with an s-wave superconductor. Here we consider parafermion and…
Spectroscopy of spin-split Andreev levels in a quantum dot with superconducting leads
Arno Bargerbos, Marta Pita-Vidal, Rok Žitko +9
We use a hybrid superconductor-semiconductor transmon device to perform spectroscopy of a quantum dot Josephson junction tuned to be in a spin-1/2 ground state with an unpaired qua…
