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…
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…
Probing entanglement across the energy spectrum of a hard-core Bose-Hubbard lattice
Amir H. Karamlou, Ilan T. Rosen, Sarah E. Muschinske +16
Entanglement and its propagation are central to understanding a multitude of physical properties of quantum systems. Notably, within closed quantum many-body systems, entanglement…
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…
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…
Spin-Orbit Torque and Nernst Effect in Bi-Sb/Co Heterostructures
Niklas Roschewsky, Emily S. Walker, Praveen Gowtham +4
Harmonic measurements of the longitudinal and transverse voltages in Bi-Sb/Co bilayers are presented. A large second harmonic voltage signal due to the ordinary Nernst effect is ob…
