Quantum sensing refers to the use of quantum properties to improve the measurement and sensing performance. Quantum sensors exploit the unique behaviors of quantum particles, such as superposition and entanglement, to achieve levels of precision and sensitivity that are not possible with classical sensors. The focus of this session is on the key concepts and methods of quantum sensing, with particular attention to various applications. Topics include, but are not limited to: magnetometers; electric-field meters; gravity meters; accelerometers; atomic clocks; optomechanical systems; Rydberg atoms; cold atoms; NV centers; superconducting circuits; etc.
