Quantum Sensing & Metrology studies how entanglement, squeezing, and coherent control let a measurement of a physical parameter — a phase, a frequency, a field strength, a spatial displacement — reach precision beyond what any strategy built only from independent, unentangled probes can achieve. It covers the sensing and estimation side of quantum information science, distinct from the computational and error-correction concerns that stay under Quantum Information & Computing.
Concepts have one canonical folder for navigation, not one exclusive field. Cross-cutting relationships to quantum information and computing, many-body physics, and device engineering remain visible through page metadata and links.
