Axion dark matter search with a photonic bandgap cavity haloscope and dielectric tuning rod over 10.25-10.45 GHz
Morgan Lynn, Ankur Agrawal, Arjun Ghosh +4
We report the development of a new widely tunable cavity and demonstrate its use in a search for dark matter axions. We achieve unloaded quality factors above , roughly $25…
XCOM: Full Mesh Network Synchronization and Low-Latency Communication for QICK (Quantum Instrumentation Control Kit)
Diego Martin, Luis H. Arnaldi, Kenneth Treptow +5
Quantum computing experiments and testbeds with large qubit counts have until recently been a privilege afforded only to large companies or quantum technologies where scaling to hu…
Protomon: A Multimode Qubit in the Fluxonium Molecule
Shashwat Kumar, Xinyuan You, Xanthe Croot +7
Qubits that are intrinsically insensitive to depolarization and dephasing errors promise to significantly reduce the overhead of fault-tolerant quantum computing. At their optimal…
Experimental advances with the QICK (Quantum Instrumentation Control Kit) for superconducting quantum hardware
Chunyang Ding, Martin Di Federico, Michael Hatridge +14
The QICK is a standalone open source qubit controller that was first introduced in 2022. In this follow-up work, we present recent experimental use cases that the QICK uniquely ena…
Tunable inductive coupler for high fidelity gates between fluxonium qubits
Helin Zhang, Chunyang Ding, D. K. Weiss +9
The fluxonium qubit is a promising candidate for quantum computation due to its long coherence times and large anharmonicity. We present a tunable coupler that realizes strong indu…
Microarchitectures for Heterogeneous Superconducting Quantum Computers
Samuel Stein, Sara Sussman, Teague Tomesh +12
Noisy Intermediate-Scale Quantum Computing (NISQ) has dominated headlines in recent years, with the longer-term vision of Fault-Tolerant Quantum Computation (FTQC) offering signifi…
Architectures for Multinode Superconducting Quantum Computers
James Ang, Gabriella Carini, Yanzhu Chen +30
Many proposals to scale quantum technology rely on modular or distributed designs where individual quantum processors, called nodes, are linked together to form one large multinode…
Neutron Tagging following Atmospheric Neutrino Events in a Water Cherenkov Detector
K. Abe, Y. Haga, Y. Hayato +301
We present the development of neutron-tagging techniques in Super-Kamiokande IV using a neural network analysis. The detection efficiency of neutron capture on hydrogen is estimate…
Let Each Quantum Bit Choose Its Basis Gates
Sophia Fuhui Lin, Sara Sussman, Casey Duckering +5
Near-term quantum computers are primarily limited by errors in quantum operations (or gates) between two quantum bits (or qubits). A physical machine typically provides a set of ba…
Experimental verification of the treatment of time-dependent flux in circuit quantization
Jacob Bryon, D. K. Weiss, Xinyuan You +5
Recent theoretical work has highlighted that quantizing a superconducting circuit in the presence of time-dependent flux generally produces Hamiltonian terms proportional to…
Testing Non-Standard Interactions Between Solar Neutrinos and Quarks with Super-Kamiokande
Kamiokande Collaboration, P. Weatherly, K. Abe +268
Non-Standard Interactions (NSI) between neutrinos and matter affect the neutrino flavor oscillations. Due to the high matter density in the core of the Sun, solar neutrinos are sui…
The QICK (Quantum Instrumentation Control Kit): Readout and control for qubits and detectors
Leandro Stefanazzi, Ken Treptow, Neal Wilcer +12
We introduce a Xilinx RFSoC-based qubit controller (called the Quantum Instrumentation Control Kit, or QICK for short) which supports the direct synthesis of control pulses with ca…
Accurate methods for the analysis of strong-drive effects in parametric gates
Alexandru Petrescu, Camille Le Calonnec, Catherine Leroux +6
The ability to perform fast, high-fidelity entangling gates is an important requirement for a viable quantum processor. In practice, achieving fast gates often comes with the penal…
