Learning-based Calibration of Flux Crosstalk in Transmon Qubit Arrays
Cora N. Barrett, Amir H. Karamlou, Sarah E. Muschinske +13
Superconducting quantum processors comprising flux-tunable data and coupler qubits are a promising platform for quantum computation. However, magnetic flux crosstalk between the fl…
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…
Mediated interactions beyond the nearest neighbor in an array of superconducting qubits
Yariv Yanay, Jochen Braumüller, Terry P. Orlando +3
We consider mediated interactions in an array of floating transmons, where each qubit capacitor consists of two superconducting pads galvanically isolated from ground. Each such pa…
Hexagonal Boron Nitride (hBN) as a Low-loss Dielectric for Superconducting Quantum Circuits and Qubits
Joel I-J. Wang, Megan A. Yamoah, Qing Li +19
Dielectrics with low loss at microwave frequencies are imperative for high-coherence solid-state quantum computing platforms. We study the dielectric loss of hexagonal boron nitrid…
Quantum transport and localization in 1d and 2d tight-binding lattices
Amir H. Karamlou, Jochen Braumüller, Yariv Yanay +16
Particle transport and localization phenomena in condensed-matter systems can be modeled using a tight-binding lattice Hamiltonian. The ideal experimental emulation of such a model…
Analog quantum simulation of the Rabi model in the ultra-strong coupling regime
Jochen Braumüller, Michael Marthaler, Andre Schneider +4
The quantum Rabi model describes the fundamental mechanism of light-matter interaction. It consists of a two-level atom or qubit coupled to a quantized harmonic mode via a transver…
Concentric transmon qubit featuring fast tunability and an anisotropic magnetic dipole moment
Jochen Braumüller, Martin Sandberg, Michael R. Vissers +10
We present a planar qubit design based on a superconducting circuit that we call concentric transmon. While employing a straightforward fabrication process using Al evaporation and…
