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…
Remote Entangling Gates for Spin Qubits in Quantum Dots using a Charge-Sensitive Superconducting Coupler
Harry Hanlim Kang, Ilan T. Rosen, Max Hays +2
We propose a method to realize microwave-activated CZ gates between two remote spin qubits in quantum dots using a charge-sensitive superconducting coupler. The qubits are longitud…
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…
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 --…
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…
