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…

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…

Implementation of a Walsh-Hadamard gate in a superconducting qutrit
M. A. Yurtalan, J. Shi, M. Kononenko +2
We have implemented a Walsh-Hadamard gate, which performs a quantum Fourier transform, in a superconducting qutrit. The qutrit is encoded in the lowest three energy levels of a cap…
