Quantum Zeno effect appears in stages

Physical Review Research, 2020
In the quantum Zeno effect, quantum measurements can block the coherent oscillation of a two level system by freezing its state to one of the measurement eigenstates. The effect is conventionally controlled by the measurement frequency. Here we study the

Quantum Zeno effect with partial measurement and noisy dynamics

Physical Review Research, 2020
We study the quantum Zeno effect (QZE) induced by continuous partial measurement in the presence of short-correlated noise in the system Hamiltonian. We study the survival probability and the onset of the QZE as a function of the measurement strength and

Distributed Dynamic Event-Triggered Control to Leader-Following Consensus of Nonlinear Multi-Agent Systems with Directed Graphs [PDF]

Entropy
This paper investigates achieving leader-following consensus in a class of multi-agent systems with nonlinear dynamics. Initially, it introduces a dynamic event-triggered strategy designed to effectively alleviate the strain on the system’s communication

A Multi-Qubit Quantum Gate Using the Zeno Effect [PDF]

Quantum, 2023
The Zeno effect, in which repeated observation freezes the dynamics of a quantum system, stands as an iconic oddity of quantum mechanics. When a measurement is unable to distinguish between states in a subspace, the dynamics within that subspace can be ...

Sufficient Conditions for the Existence of Zeno Behavior [PDF]

Proceedings of the 44th IEEE Conference on Decision and Control, 2006
In this paper, sufficient conditions for the existence of Zeno behavior in a class of hybrid systems are given; these are the first sufficient conditions on Zeno of which the authors are aware for hybrid systems with nontrivial dynamics. This is achieved by considering a class of hybrid systems termed diagonal first quadrant (DFQ) hybrid systems.

Zeno: An Interactive Framework for Behavioral Evaluation of Machine Learning

Proceedings of the 2023 CHI Conference on Human Factors in Computing Systems, 2023
Machine learning models with high accuracy on test data can still produce systematic failures, such as harmful biases and safety issues, when deployed in the real world. To detect and mitigate such failures, practitioners run behavioral evaluation of their models, checking model outputs for specific types of inputs.

The quantum Zeno and anti-Zeno effects with driving fields in the weak and strong coupling regimes

Scientific Reports, 2021
Repeated measurements in quantum mechanics can freeze (the quantum Zeno effect) or enhance (the quantum anti-Zeno effect) the time-evolution of a quantum system.

On the Zeno behavior of linear complementarity systems [PDF]

Proceedings of the 40th IEEE Conference on Decision and Control (Cat. No.01CH37228), 2002
In this paper, the so-called Zeno phenomenon is addressed for linear complementarity systems which are interconnections of linear systems and complementarity conditions. We present some sufficient conditions for absence of Zeno behavior. It is also shown that the zero state, which is the most obvious candidate for being a Zeno state, cannot be a Zeno ...
