Component-Level Inverse Design of Transmon Qubits Using Neural Networks
Olivia Seidel, Firas Abouzahr, Abhishek Chakraborty +11
Designing a superconducting qubit to realize specific Hamiltonian parameters typically requires iterating through a time and compute-intensive forward loop in which the designer ch…
Performance of a SuperCDMS HVeV Detector with Sub-eV Energy Resolution and Single Charge-sensitivity
Kyle Kennard, Aditi Pradeep, Mason Buchanan +41
We present a detailed characterization of a new generation of athermal-phonon single-charge sensitive Si HVeV detectors, the best of which achieved 589~meV~~5~meV baseline res…
Accelerating Surface Radiation Content to Investigate the Impact of Radon Progeny on Superconducting Qubits
Sagar S. Poudel, Dylan J. Temples, Ryan Linehan +8
Ionizing radiation in the form of , , , and additional high-energy particles can induce decoherence via phonon and quasiparticle poisoning in superconducting qubits. Re…
Characterization of Aluminum Microwave SQUID Multiplexers for CENS Detection
James Amidei, Antoine Armatol, Corinne Augier +92
We present the design, fabrication, and characterization of an aluminum-based six-channel microwave SQUID multiplexer (MUX) prototype for transition-edge sensor (TES) readout i…
A First Demonstration of the SQUAT Detector Architecture: Direct Measurement of Resonator-Free Charge-Sensitive Transmons
H. Magoon, T. Aralis, T. Dyson +18
The Superconducting Quasiparticle-Amplifying Transmon (SQUAT) is a new sensor architecture for THz (meV) detection based on a weakly charge-sensitive transmon directly coupled to a…
Characterization of mini-CryoCube detectors from the Ricochet experiment commissioning at the Institut Laue-Langevin
Antoine Armatol, Corinne Augier, Louis Bailly-Salins +83
The Ricochet experiment aims to measure the coherent elastic neutrino-nucleus scattering process from antineutrinos emitted by a research nuclear reactor operated by the Institut L…
