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 tunable three-body interactions between superconducting qubits
Tim Menke, William P. Banner, Thomas R. Bergamaschi +16
Nonpairwise multi-qubit interactions present a useful resource for quantum information processors. Their implementation would facilitate more efficient quantum simulations of molec…
Distinguishing multi-spin interactions from lower-order effects
Thomas R. Bergamaschi, Tim Menke, William P. Banner +5
Multi-spin interactions can be engineered with artificial quantum spins. However, it is challenging to verify such interactions experimentally. Here we describe two methods to char…
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…
