Fidelity-Aware Frequency Allocation and Transpilation Co-Design for Tunable Coupler Quantum Systems
Dylan VanAllen, Evan McKinney, Israa G. Yusuf +5
Frequency crowding is a fundamental limitation in superconducting quantum architectures, particularly in tunable-coupler systems. We present a framework that explicitly models both…
A superconducting quantum circuit single artificial atom maser
Maria Mucci, Nicholas Hougland, Chun-Che Wang +4
We demonstrate a circuit QED analog of an atomic micromaser that utilizes an artificial, multi level atom, pumped into a population-inverted state by a microwave tone, as the gain…
Tunable anharmonicity in Sn-InAs nanowire transmons beyond the short junction limit
Amrita Purkayastha, Amritesh Sharma, Param J. Patel +11
The anharmonicity of a transmon qubit, defined as the difference in energy level spacing, is a key design parameter. In transmons built from hybrid superconductor-semiconductor Jos…
Single-shot Quantum State Classification via Nonlinear Quantum Amplification
Elif Cüce, Elif Cüce, Saeed A. Khan +4
Quantum amplifiers are intrinsically nonlinear systems whose performance limits are set by quantum mechanics. In quantum measurement, amplifier operation is conventionally optimize…
An Eclipse-Ballooning Study of Shadow Bands During the April 2024 Total Eclipse
Giana Deskevich, Norris Bach, Kristian Borysiak +16
In this study we searched for shadow bands associated with the total solar eclipse of April 8, 2024. Our aim was to improve our understanding of their origin. Shadow bands are deba…
High-fidelity Quantum Readout Processing via an Embedded SNAIL Amplifier
Leon Bello, Boris Mesits, Michael Hatridge +1
Scalable, high-fidelity quantum-state readout remains a central challenge in the development of large-scale superconducting quantum processors. Conventional dispersive readout arch…
