Violation of No‐Signaling on a Public Quantum Computer

open access: yesAdvanced Quantum Technologies, EarlyView.
No‐signaling is the simplest consequence of lack of communication, assumed in Bell tests of nonlocality. Its violation indicated serious malfunction of the system. Tested on IBM Quantum, no‐signaling turned out to be violated at various configurations. As simple crosstalk cannot explain it, an urgent investigation of the origin is necessary.

The role of identification in data‐driven policy iteration: A system theoretic study

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
Abstract The goal of this article is to study fundamental mechanisms behind so‐called indirect and direct data‐driven control for unknown systems. Specifically, we consider policy iteration applied to the linear quadratic regulator problem. Two iterative procedures, where data collected from the system are repeatedly used to compute new estimates of ...

Frequency Shaping for Improving a Trade‐Off Between Control and Privacy Performance: Beyond Differential Privacy

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT In privacy protection of control systems, a trade‐off between control performance and privacy level is often pointed out. Our goal in this paper is to improve this trade‐off by shaping the frequency of noise added for privacy protection when the control objective is to track a reference signal, which is taken as a piece of information whose ...
