Unified scaling of transmon sub-resonant parametric drive strength limits
Jacob Repicky, Girish Kumbhar, Mingkang Xia +6
Achieving fast gates and high-fidelity readout in superconducting quantum circuits often benefits from the use of large amplitude microwave drives. As the strength increases, unwan…
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…
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…
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…
Single-shot Quantum State Classification via Nonlinear Quantum Amplification
Elif Cüce, Saeed A. Khan, Boris Mesits +2
Quantum amplifiers are intrinsically nonlinear systems whose performance limits are set by quantum mechanics. In quantum measurement, amplifier operation is conventionally optimize…
Quartz phononic crystal resonators for hybrid acoustic quantum memories
Yang Hu, Angad Gupta, Jacob Repicky +2
Circuit quantum acoustodynamics systems have emerged as a promising platform for quantum information by coupling superconducting qubits to mechanical resonators, with their long-li…
Transmon qubit using Sn as a junction superconductor
Amrita Purkayastha, Amritesh Sharma, Param J. Patel +11
Superconductor qubits typically use aluminum-aluminum oxide tunnel junctions to provide the non-linear inductance. Junctions with semiconductor barriers make it possible to vary th…
Exceeding the Parametric Drive Strength Threshold in Nonlinear Circuits
Mingkang Xia, Cristóbal Lledó, Matthew Capocci +7
Superconducting quantum circuits rely on strong drives to implement fast gates, high-fidelity readout, and state stabilization. However, these drives can induce uncontrolled excita…
The waves-in-space Purcell effect for superconducting qubits
Param Patel, Mingkang Xia, Chao Zhou +5
Quantum information processing, especially with quantum error correction, requires both long-lived qubits and fast, quantum non-demolition readout. In superconducting circuits this…
Spectator-Aware Frequency Allocation in Tunable-Coupler Quantum Architectures
Evan McKinney, Israa G. Yusuf, Girgis Falstin +3
This paper addresses frequency crowding in SNAIL-based superconducting quantum modules. First, we present design constraints by describing a physical model for realizable gates wit…
A neural processing approach to quantum state discrimination
Saeed A. Khan, Fangjun Hu, Gerasimos Angelatos +2
Although linear quantum amplification has proven essential to the processing of weak quantum signals, extracting higher-order quantum features such as correlations in principle dem…
