Abstract

Quantum Sensing is the process in which we use a quantum system to acquire information about a physical quantity. It is becoming a vital process in science and technology, with applications in the measurement of e.g. gravitational waves, forces, electromagnetic fields, and the state of qubits. The course will treat both theoretical and experimental aspects of this topic.

Objective

The course provides an insight into various concepts, techniques and limitations in quantum sensing and metrology. When the course is over, you will understand and be able to calculate the accuracy/sensitivity of quantum sensing protocols in a variety of settings. You will understand why and when quantum mechanics allows for an advantage over classical protocols and how to engineer your system to achieve high accuracy.

Content

The course covers a selection of quantum sensing techniques and precision limitations. Topics include: historical overview and motications, quantum sensing protocols and their sensitivity, method of moments, quantum Fisher information (Cramér–Rao bound and local estimation), standard quantum limit, Heisenberg limit, squeezed/nonclassical states, measurement theory, concrete applications (e.g. gravitational wave detection, magnetometry, force sensing), experimental techniques for state preparation and detection, seminal demonstrations, multi-parameter sensing, open questions.
