Optimal schedule of multi-channel quantum Zeno dragging with application to solving the k-SAT problem
Yipei Zhang, Alain Sarlette, Philippe Lewalle +3
The paper analyzes how to optimally schedule multi-channel quantum Zeno dragging—using simultaneous measurements of non‑commuting observables—to drive a quantum system toward a tar…
Topological state permutations in time-modulated non-Hermitian multiqubit systems with suppressed non-adiabatic transitions
Ievgen I. Arkhipov, Philippe Lewalle, Franco Nori +2
Non-Hermitian systems have been at the center of intense research for over a decade, partly due to their nontrivial energy topology formed by intersecting Riemann manifolds with br…
Noise-Canceling Quantum Feedback: non-Hermitian Dynamics with Applications to State Preparation and Magic State Distillation
Tathagata Karmakar, Philippe Lewalle, Yipei Zhang +1
Time-continuous quantum measurement allows for the tracking of a quantum system in real time via sequences of short, and individually weak, measurement intervals. Such measurements…
Optimal Zeno Dragging for Quantum Control: A Shortcut to Zeno with Action-based Scheduling Optimization
Philippe Lewalle, Yipei Zhang, K. Birgitta Whaley
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…
