Modular Many-Body Quantum Sensors

Explore a comprehensive lecture on modular many-body quantum sensors presented by Dr. Chiranjib Mukhopadhyay from UESTC, Chengdu, China. Delve into the systematic development of a modular approach for introducing multiple phase transitions in many-body systems, enabling enhanced sensing precision beyond classical limits. Discover how this method expands the region of quantum-enhanced precision by encompassing newly created phase boundaries in both symmetry-breaking and topological quantum sensors. Learn about the inheritance of universality class in symmetry-breaking sensors and the creation of multiple bands leading to rich phase diagrams in topological sensors. Understand how Heisenberg scaling for Hamiltonian parameter estimation is achieved at all phase boundaries, resulting in a global sensor that significantly outperforms uniform probes. Gain insights into the potential applications and implications of this innovative approach in quantum sensing technology.
