Probing entanglement across the energy spectrum of a hard-core Bose-Hubbard lattice
Amir H. Karamlou, Ilan T. Rosen, Sarah E. Muschinske +16
Entanglement and its propagation are central to understanding a multitude of physical properties of quantum systems. Notably, within closed quantum many-body systems, entanglement…
High-Fidelity, Frequency-Flexible Two-Qubit Fluxonium Gates with a Transmon Coupler
Leon Ding, Max Hays, Youngkyu Sung +16
We propose and demonstrate an architecture for fluxonium-fluxonium two-qubit gates mediated by transmon couplers (FTF, for fluxonium-transmon-fluxonium). Relative to architectures…
Evolution of Flux Noise in Superconducting Qubits with Weak Magnetic Fields
David A. Rower, Lamia Ateshian, Lauren H. Li +18
The microscopic origin of magnetic flux noise in superconducting circuits has remained an open question for several decades despite extensive experimental and theoretical inv…
Distinguishing parity-switching mechanisms in a superconducting qubit
Spencer Diamond, Valla Fatemi, Max Hays +8
Single-charge tunneling is a decoherence mechanism affecting superconducting qubits, yet the origin of excess quasiparticle excitations (QPs) responsible for this tunneling in supe…
Microwave susceptibility observation of interacting many-body Andreev states
V. Fatemi, P. D. Kurilovich, M. Hays +10
Electrostatic charging affects the many-body spectrum of Andreev states, yet its influence on their microwave properties has not been elucidated. We developed a circuit quantum ele…
Coherent manipulation of an Andreev spin qubit
M. Hays, V. Fatemi, D. Bouman +9
Two promising architectures for solid-state quantum information processing are electron spins in semiconductor quantum dots and the collective electromagnetic modes of superconduct…
Spin Coherent Manipulation in Josephson Weak Links
Javier Cerrillo, Max Hays, Valla Fatemi +1
Novel designs of Josephson weak links based on semiconducting nanowires combined with circuit QED techniques have enabled the resolution of their fine structure due to spin-orbit i…
Continuous monitoring of a trapped, superconducting spin
M. Hays, V. Fatemi, K. Serniak +7
Readout and control of fermionic spins in solid-state systems are key primitives of quantum information processing and microscopic magnetic sensing. The highly localized nature of…
Direct Dispersive Monitoring of Charge Parity in Offset-Charge-Sensitive Transmons
K. Serniak, S. Diamond, M. Hays +5
A striking characteristic of superconducting circuits is that their eigenspectra and intermode coupling strengths are well predicted by simple Hamiltonians representing combination…
Hot non-equilibrium quasiparticles in transmon qubits
K. Serniak, M. Hays, G. de Lange +6
Non-equilibrium quasiparticle excitations degrade the performance of a variety of superconducting circuits. Understanding the energy distribution of these quasiparticles will yield…
Direct microwave measurement of Andreev-bound-state dynamics in a proximitized semiconducting nanowire
M. Hays, G. de Lange, K. Serniak +6
The modern understanding of the Josephson effect in mesosopic devices derives from the physics of Andreev bound states, fermionic modes that are localized in a superconducting weak…
