Entanglement-Preserving Limit Cycles from Sequential Quantum Measurements and Feedback
Philippe Lewalle, Cyril Elouard, Andrew N. Jordan
Entanglement generation and preservation is a key task in quantum information processing, and a variety of protocols exist to entangle remote qubits via measurement of their sponta…

Measuring Fluorescence to Track a Quantum Emitter's State: A Theory Review
Philippe Lewalle, Sreenath K. Manikandan, Cyril Elouard +1
We review the continuous monitoring of a qubit through its spontaneous emission, at an introductory level. Contemporary experiments have been able to collect the fluorescence of an…

Chaos in Continuously Monitored Quantum Systems: An Optimal Path Approach
Philippe Lewalle, John Steinmetz, Andrew N. Jordan
We predict that continuously monitored quantum dynamics can be chaotic. The optimal paths between past and future boundary conditions can diverge exponentially in time when there i…
