Squeezing Quantum Uncertainty by Entangling Atoms - From Measurement Precision to Quantum Computation

Simons Foundation via YouTube

Overview

Explore cutting-edge quantum physics research in this 56-minute lecture where Dr. Monika Schleier-Smith demonstrates how engineering entanglement through laser-manipulated atomic clouds can reduce quantum uncertainty in precision measurements. Learn about the fundamental challenges of quantum uncertainty in measuring time, magnetic fields, acceleration, and gravity, and discover how controlled quantum correlations can enhance measurement precision. Delve into experimental techniques involving atoms and photons, with applications ranging from quantum computing to tabletop quantum gravity simulations. Follow along as the lecture progresses from basic concepts like quantum coins and atomic clocks to advanced topics including programmable entanglement, experimental setups, optimization strategies, and emerging frontiers in understanding quantum void and geometry. Gain insights into the verification of entanglement between subsystems and the programming of entanglement graphs in this comprehensive presentation from the Simons Foundation.
