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…
Decoherence in Andreev spin qubits
Silas Hoffman, Max Hays, Kyle Serniak +2
We theoretically study the dephasing of an Andreev spin qubit (ASQ) due to electric and magnetic noise. Using a tight-binding model, we calculate the Andreev states formed in a Jos…
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…
Characterization of superconducting through-silicon vias as capacitive elements in quantum circuits
Thomas M. Hazard, Wayne Woods, Danna Rosenberg +13
The large physical size of superconducting qubits and their associated on-chip control structures presents a practical challenge towards building a large-scale quantum computer. In…
Evolution of Flux Noise in Superconducting Qubits with Weak Magnetic Fields
David A. Rower, Lamia Ateshian, Lauren H. Li +18
The microscopic origin of magnetic flux noise in superconducting circuits has remained an open question for several decades despite extensive experimental and theoretical inv…
