Arbitrary n-Qubit State Transfer Implemented by Coherent Control and Simplest Switchable Local Noise

2016 · arXiv (Cornell University)

We study reachable sets of open n-qubit quantum systems, whose coherent parts are under full unitary control, by adding as a further degree of incoherent control switchable Markovian noise on a single qubit. In particular, …

Flux-qubit readout in the persistent-current basis at arbitrary bias points

2020 · Physical Review A

Common flux-qubit readout schemes are qubit dominated, meaning they measure in the energy eigenbasis of the qubit. For various applications, measurements in a basis different from the energy eigenbasis are required. Here we present an …

On the physical realizability of quantum stochastic walks

2016 · arXiv (Cornell University)

Quantum walks are a promising framework that can be used to both understand and implement quantum information processing tasks. The quantum stochastic walk is a recently developed framework that combines the concept of a quantum …

Benchmarking optimization algorithms for automated calibration of quantum devices

2026 · New Journal of Physics

Abstract We present the results of a comprehensive study of optimization algorithms for the calibration of quantum devices. As part of our ongoing efforts to automate bring-up, tune-up, and system identification procedures, we investigate a …
