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…
Speed limits for two-qubit gates with weakly anharmonic qubits
Sahel Ashhab, Fumiki Yoshihara, Tomoko Fuse +3
We consider the implementation of two-qubit gates when the physical systems used to realize the qubits possess additional quantum states in the accessible energy range. We use opti…
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…
Customized quantum annealing schedules
Mostafa Khezri, Xi Dai, Rui Yang +3
In a typical quantum annealing protocol, the system starts with a transverse field Hamiltonian which is gradually turned off and replaced by a longitudinal Ising Hamiltonian. The g…
