Flat-band (de)localization emulated with a superconducting qubit array
Ilan T. Rosen, Sarah Muschinske, Cora N. Barrett +10
Arrays of coupled superconducting qubits are analog quantum simulators able to emulate a wide range of tight-binding models in parameter regimes that are difficult to access or adj…
Qubit-State Purity Oscillations from Anisotropic Transverse Noise
David A. Rower, Kotaro Hida, Lamia Ateshian +13
We explore the dynamics of qubit-state purity in the presence of transverse noise that is anisotropically distributed in the Bloch-sphere XY plane. We perform Ramsey experiments wi…
Deterministic remote entanglement using a chiral quantum interconnect
Aziza Almanakly, Beatriz Yankelevich, Max Hays +13
Quantum interconnects facilitate entanglement distribution between non-local computational nodes. For superconducting processors, microwave photons are a natural means to mediate t…
Suppressing Counter-Rotating Errors for Fast Single-Qubit Gates with Fluxonium
David A. Rower, Leon Ding, Helin Zhang +12
Qubit decoherence unavoidably degrades the fidelity of quantum logic gates. Accordingly, realizing gates that are as fast as possible is a guiding principle for qubit control, nece…
Superfluid Stiffness and Flat-Band Superconductivity in Magic-Angle Graphene Probed by cQED
Miuko Tanaka, Joel Î-j. Wang, Thao H. Dinh +16
The physics of superconductivity in magic-angle twisted bilayer graphene (MATBG) is a topic of keen interest in moiré systems research, and it may provide insight into the pairing…
Near-ultrastrong nonlinear light-matter coupling in superconducting circuits
Yufeng Ye, Jeremy B. Kline, Alec Yen +9
The interaction between an atom and an electromagnetic mode of a resonator is of both fundamental interest and is ubiquitous in quantum technologies. Most prior work studies a line…
Interferometric Purcell suppression of spontaneous emission in a superconducting qubit
Alec Yen, Yufeng Ye, Kaidong Peng +8
In superconducting qubits, suppression of spontaneous emission is essential to achieve fast dispersive measurement and reset without sacrificing qubit lifetime. We show that resona…
Implementing a synthetic magnetic vector potential in a 2D superconducting qubit array
Ilan T. Rosen, Sarah Muschinske, Cora N. Barrett +14
Superconducting quantum processors are a compelling platform for analog quantum simulation due to the precision control, fast operation, and site-resolved readout inherent to the h…
Dephasing in Fluxonium Qubits from Coherent Quantum Phase Slips
Mallika T. Randeria, Thomas M. Hazard, Agustin Di Paolo +12
Phase slips occur across all Josephson junctions (JJs) at a rate that increases with the impedance of the junction. In superconducting qubits composed of JJ-array superinductors --…
Directional emission of a readout resonator for qubit measurement
Alec Yen, Yufeng Ye, Kaidong Peng +8
We propose and demonstrate transmission-based dispersive readout of a superconducting qubit using an all-pass resonator, which preferentially emits readout photons toward the outpu…
Abatement of Ionizing Radiation for Superconducting Quantum Devices
B. Loer, P. M. Harrington, B. Archambault +15
Ionizing radiation has been shown to reduce the performance of superconducting quantum circuits. In this report, we evaluate the expected contributions of different sources of ambi…
Synchronous Detection of Cosmic Rays and Correlated Errors in Superconducting Qubit Arrays
Patrick M. Harrington, Mingyu Li, Max Hays +13
Quantum information processing at scale will require sufficiently stable and long-lived qubits, likely enabled by error-correction codes. Several recent superconducting-qubit exper…
