Above 99.9% Fidelity Single-Qubit Gates, Two-Qubit Gates, and Readout in a Single Superconducting Quantum Device
Fabian Marxer, Jakub Mrożek, Joona Andersson +64
Achieving high-fidelity single-qubit gates, two-qubit gates, and qubit readout is critical for building scalable, error-corrected quantum computers. However, device parameters that…
Quantum algorithms for simulating systems coupled to bosonic modes using a hybrid resonator-qubit quantum computer
Juha Leppäkangas, Pascal Stadler, Dmitry Golubev +14
Modeling composite systems of spins or electrons coupled to bosonic modes is of significant interest for many fields of applied quantum physics and chemistry. A quantum simulation…
Quantum error detection in qubit-resonator star architecture
Florian Vigneau, Sourav Majumder, Aniket Rath +13
Achieving industrial quantum advantage is unlikely without the use of quantum error correction (QEC). Other QEC codes beyond surface code are being experimentally studied, such as…
A Superconducting Qubit-Resonator Quantum Processor with Effective All-to-All Connectivity
Michael Renger, Jeroen Verjauw, Nicola Wurz +62
In this work we introduce a superconducting quantum processor architecture that uses a transmission-line resonator to implement effective all-to-all connectivity between six transm…
A Compact Cold-Atom Interferometer with a High Data-Rate Grating Magneto-Optical Trap and a Photonic-Integrated-Circuit-Compatible Laser System
Jongmin Lee, Roger Ding, Justin Christensen +16
The extreme miniaturization of a cold-atom interferometer accelerometer requires the development of novel technologies and architectures for the interferometer subsystems. Here we…
Reconfigurable quantum phononic circuits via piezo-acoustomechanical interactions
Jeffrey C. Taylor, Eric Chatterjee, William F. Kindel +2
We show that piezoelectric strain actuation of acoustomechanical interactions can produce large phase velocity changes in an existing quantum phononic platform: aluminum nitride on…
Characterization of Suspended Membrane Waveguides towards a Photonic Atom Trap Integrated Platform
Michael Gehl, William Kindel, Nicholas Karl +10
We demonstrate an optical waveguide device, capable of supporting the high, in-vacuum, optical power necessary for trapping a single atom or a cold atom ensemble with evanescent fi…
Results from phase 1 of the HAYSTAC microwave cavity axion experiment
L. Zhong, S. Al Kenany, K. M. Backes +18
We report on the results from a search for dark matter axions with the HAYSTAC experiment using a microwave cavity detector at frequencies between 5.6-5.8. We exclude a…
Using deep learning to reveal the neural code for images in primary visual cortex
William F. Kindel, Elijah D. Christensen, Joel Zylberberg
Primary visual cortex (V1) is the first stage of cortical image processing, and a major effort in systems neuroscience is devoted to understanding how it encodes information about…
Design and Operational Experience of a Microwave Cavity Axion Detector for the 20-100 micro-eV Range
S. Al Kenany, M. A. Anil, K. M. Backes +17
We describe a dark matter axion detector designed, constructed, and operated both as an innovation platform for new cavity and amplifier technologies and as a data pathfinder in th…

Generation and efficient measurement of single photons from fixed frequency superconducting qubits
William F. Kindel, M. D. Schroer, K. W. Lehnert
We demonstrate and evaluate an on-demand source of single itinerant microwave photons. Photons are generated using a highly coherent, fixed-frequency qubit-cavity system, and a pro…
