Abstract

Quantum Sensing is the process in which we acquire information about a physical quantity via measurements using quantum systems. It is a vital process in all quantum technologies. The course will focus on theoretical concepts that impact future implementations of quantum technologies. The course is useful for students who wish to undertake both experimental and theoretical work.

Objective

The course provides an insight into various 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. Particular focus will be put on theoretical concepts that impact future implementations of quantum technologies. Topics include: historical overview and examples, quantum sensing protocols and their sensitivity, quantum Fisher information (Cramér–Rao bound and local estimation), Bayesian estimation theory, standard quantum limit, Heisenberg limit, squeezed states, non-demolition measurements, and examples of accurate quantum sensors.
