Enhanced Sensitivity near a Quantum Exceptional Point in the Absence of Engineered Dissipation
Réouven Assouly, Harry Hanlim Kang, Aziza Almanakly +8
Non-Hermitian systems exhibit phenomena absent from Hermitian systems, including exceptional points (EPs), at which two or more eigenvectors coalesce. Conventional implementations…
Driven-dissipative entanglement of distant giant atoms
Aziza Almanakly, Ariadna Soro, Alejandro Vivas-Viaña +15
Quantum interconnects distribute entanglement via controlled light-matter interactions for quantum computing and sensing applications. Many entanglement generation schemes use cohe…
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 in…
Characterization of Radiation-Induced Errors in Superconducting Qubits Protected with Various Gap-Engineering Strategies
H. Douglas Pinckney, Thomas McJunkin, Alan W. Hunt +26
Impacts from high-energy particles cause correlated errors in superconducting qubits by increasing the quasiparticle density in the vicinity of the Josephson junctions (JJs). Such…
Characterization and Comparison of Energy Relaxation in Fluxonium Qubits
Kate Azar, Lamia Ateshian, Mallika T. Randeria +19
Fluxonium superconducting qubits have demonstrated long coherence times and high single- and two-qubit gate fidelities, making them a favorable building block for superconducting q…
Distinguishing types of correlated errors in superconducting qubits
Hannah P. Binney, H. Douglas Pinckney, Kate Azar +15
Errors in superconducting qubits that are correlated in time and space can pose problems for quantum error correction codes. Radiation from cosmic and terrestrial sources can incre…
