Optimal Zeno Dragging for Quantum Control: A Shortcut to Zeno with Action-based Scheduling Optimization

Kavli Affiliate: Birgitta Whaley | First 5 Authors: Philippe Lewalle, Yipei Zhang, K. Birgitta Whaley, , | Summary: The quantum Zeno effect asserts that quantum measurements inhibit simultaneous unitary dynamics when the "collapse" events are sufficiently strong and frequent. This applies in the limit of strong continuous measurement or dissipation. It is possible to implement […]
