Decoherence of a tunable capacitively shunted flux qubit
R. Trappen, X. Dai, M. A. Yurtalan +19
Quantum annealing is a method to solve optimization problems that leverages quantum tunneling in a coupled qubit system. We present a detailed study of the coherence of a tunable c…
Optimizing for periodicity: a model-independent approach to flux crosstalk calibration for superconducting circuits
X. Dai, R. Trappen, R. Yang +12
Flux tunability is an important engineering resource for superconducting circuits. Large-scale quantum computers based on flux-tunable superconducting circuits face the problem of…
Dissipative Landau-Zener tunneling in the crossover regime from weak to strong environment coupling
X. Dai, R. Trappen, H. Chen +22
Landau-Zener tunneling, which describes the transition in a two-level system during a sweep through an anti-crossing, is a model applicable to a wide range of physical phenomena. R…
Demonstration of long-range correlations via susceptibility measurements in a one-dimensional superconducting Josephson spin chain
Daniel M. Tennant, Xi Dai, Antonio J. Martinez +20
Spin chains have long been considered an effective medium for long-range interactions, entanglement generation, and quantum state transfer. In this work, we explore the properties…
Calibration of flux crosstalk in large-scale flux-tunable superconducting quantum circuits
X. Dai, D. M. Tennant, R. Trappen +16
Magnetic flux tunability is an essential feature in most approaches to quantum computing based on superconducting qubits. Independent control of the fluxes in multiple loops is ham…
Magnetocaloric properties of an inhomogeneous magnetic thin film of 7.6 nm LaSrMnO grown on SrTiO
Navid Mottaghi, Robbyn B. Trappen, Saeed Yousefi +2
Magnetocaloric properties of an inhomogeneous magnetic system of a 7.6 nm LaSrMnO consisting of superparamagnetic (SPM) with blocking temperature ( $T_B…
Phase diagram of a three-dimensional antiferromagnet with random magnetic anisotropy
Felio A. Perez, Pavel Borisov, Trent A. Johnson +5
Three-dimensional (3D) antiferromagnets with random magnetic anisotropy (RMA) experimentally studied to date do not have random single-ion anisotropies, but rather have competing t…
