Explore a 53-minute lecture on "Estimating Parameters by Fitting Correlation Functions of Continuous Quantum" delivered by Pierre Guilmin at the International Centre for Theoretical Sciences. This presentation is part of the "Quantum Trajectories" program organized by Michel Bauer, Cedric Bernardin, Raphael Chetrite, and Abhishek Dhar. The lecture addresses theoretical challenges in quantum physics during a period when advances in high-speed electronics and low-temperature technologies have transformed quantum matter research. Learn about the theoretical foundations supporting the "second quantum revolution" that enables quantum-based encryption, communication, and computing implementations. The program focuses on three key areas: Quantum trajectories and control, Measurement induced phase transitions, and Quantum information and computation, bringing together theoretical physicists, experimentalists, and mathematicians to foster collaboration in these interconnected fields.
