Ultra-dispersive resonator readout of a quantum-dot qubit using longitudinal coupling
Benjamin Harpt, J. Corrigan, Nathan Holman +10
We perform readout of a quantum-dot hybrid qubit coupled to a superconducting resonator through a parametric, longitudinal interaction mechanism. Our experiments are performed with…
Quantum dynamics of semiconductor quantum dot Josephson junctions
Utkan Güngördü, Rusko Ruskov, Silas Hoffman +3
Josephson junctions constructed from superconductor-semiconductor-superconductor heterostructures have been used to realize a variety of voltage-tunable superconducting quantum dev…
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…
Quantum-Coherent Nanoscience
Andreas J. Heinrich, William D. Oliver, Lieven Vandersypen +7
For the past three decades, nanoscience has widely affected many areas in physics, chemistry, and engineering, and has led to numerous fundamental discoveries as well as applicatio…
Hexagonal Boron Nitride (hBN) as a Low-loss Dielectric for Superconducting Quantum Circuits and Qubits
Joel I-J. Wang, Megan A. Yamoah, Qing Li +19
Dielectrics with low loss at microwave frequencies are imperative for high-coherence solid-state quantum computing platforms. We study the dielectric loss of hexagonal boron nitrid…
Quantum emulation of coherent backscattering in a system of superconducting qubits
Ana Laura Gramajo, Dan Campbell, Bharath Kannan +8
In condensed matter systems, coherent backscattering and quantum interference in the presence of time-reversal symmetry lead to well-known phenomena such as weak localization (WL)…
Photoluminescence decomposition analysis: a technique to characterize NV creation in diamond
Scott Alsid, John Barry, Linh Pham +4
Treatment of lab-grown diamond by electron irradiation and annealing has enabled quantum sensors based on negatively-charged nitrogen-vacancy (NV) centers to demonstrate…
Quantum coherent control of a hybrid superconducting circuit made with graphene-based van der Waals heterostructures
Joel I-Jan Wang, Daniel Rodan-Legrain, Landry Bretheau +14
Quantum coherence and control is foundational to the science and engineering of quantum systems. In van der Waals (vdW) materials, the collective coherent behavior of carriers has…
Observation of the SU(4) Kondo state in a double quantum dot
A. J. Keller, S. Amasha, I. Weymann +6
Central to condensed matter physics are quantum impurity models, which describe how a local degree of freedom interacts with a continuum. Surprisingly, these models are often unive…
Time-Reversal Symmetry and Universal Conductance Fluctuations in a Driven Two-Level System
Simon Gustavsson, Jonas Bylander, William D. Oliver
In the presence of time-reversal symmetry, quantum interference gives strong corrections to the electric conductivity of disordered systems. The self-interference of an electron wa…
Flux-charge duality and topological quantum phase fluctuations in quasi-one-dimensional superconductors
Andrew J. Kerman
It has long been thought that macroscopic phase coherence breaks down in effectively lower-dimensional superconducting systems even at zero temperature due to enhanced topological…
A metastable superconducting qubit
Andrew J. Kerman
We propose a superconducting qubit design, based on a tunable RF-SQUID and nanowire kinetic inductors, which has a dramatically reduced transverse electromagnetic coupling to its e…
Quantum Phase Tomography of a Strongly Driven Qubit
M. S. Rudner, A. V. Shytov, L. S. Levitov +4
The interference between repeated Landau-Zener transitions in a qubit swept through an avoided level crossing results in Stueckelberg oscillations in qubit magnetization. The resul…
