Microwave quantum diode
Rishabh Upadhyay, Dmitry S. Golubev, Yu-Cheng Chang +4
The fragile nature of quantum circuits is a major bottleneck to scalable quantum applications. Operating at cryogenic temperatures, quantum circuits are highly vulnerable to amplif…
Electromagnetic Simulation and Microwave Circuit Approach of Heat Transport in Superconducting Qubits
Christoforus Dimas Satrya, Andrew Guthrie, Ilari Mäkinen +1
The study of quantum heat transport in superconducting circuits is significant for further understanding the connection between quantum mechanics and thermodynamics, and for possib…
A Cooper-Pair Box Coupled to Two Resonators: An Architecture for a Quantum Refrigerator
Andrew Guthrie, Christoforus Dimas Satrya, Yu-Cheng Chang +3
Superconducting circuits present a promising platform with which to realize a quantum refrigerator. Motivated by this, we fabricate and perform spectroscopy of a gated Cooper-pair…
Robust strong coupling architecture in circuit quantum electrodynamics
Rishabh Upadhyay, George Thomas, Yu-Cheng Chang +5
We report on a robust method to achieve strong coupling between a superconducting flux qubit and a high-quality quarter-wavelength coplanar waveguide resonator. We demonstrate the…
On the origin of the controversial electrostatic field effect in superconductors
Ilia Golokolenov, Andrew Guthrie, Sergey Kafanov +2
In semiconductor electronics, the field-effect refers to the control of electrical conductivity in nanoscale devices, which underpins the field-effect transistor, one of the corner…
Nanoscale Real-Time Detection of Quantum Vortices at Millikelvin Temperatures
A. Guthrie, S. Kafanov, M. T. Noble +6
Since we still lack a theory of classical turbulence, attention has focused on the conceptually simpler turbulence in quantum fluids. Can such systems of identical singly-quantized…
Multimode probing of superfluid by tuning forks
A. Guthrie, R. P. Haley, A. Jennings +9
Flexural mode vibrations of miniature piezoelectric tuning forks (TF) are known to be highly sensitive to superfluid excitations and quantum turbulence in and $\mat…
Detecting the "phonon wind" in superfluid by a nanomechanical resonator
A. M. Guenault, A. Guthrie, R. P. Haley +8
Nanoscale mechanical resonators are widely utilized to provide high sensitivity force detectors. Here we demonstrate that such high quality factor resonators immersed in superfluid…
Driving nanomechanical resonators by phonon flux in superfluid \(\mathbf{^4He}\)
A. M. Guénault, A. Guthrie, R. P. Haley +10
We report on nanomechanical resonators with very high-quality factors operated as mechanical probes in liquid helium \(^4\mathrm{He}\), with special attention to the superfluid reg…
