additional remarks Amongst the various quantum technologies being developed, quantum sensing stands out: It has become a real-world application operating at room temperature and is being used to measure magnetic and electric fields, temperature, pressure and, yes, gravitation. This module will introduce you to the basic physics behind this exciting technology, will demonstrate a specific realisation based on so-called color centers in considerable detail and will discuss how to push the limits of quantum sensing. We will start by reviewing quantum mechanical two-level systems and their representation in the Bloch sphere, spins and their dynamics including relaxation and decoherence as well as magnetic resonance and the pulse sequences used to study it. We will introduce the nitrogen-vacancy complex in diamond and will learn how to measure dc and ac magnetometry using this atomic scale sensor to realise, e.g., NMR spectrometers capable of analysing minute samples. In the second part of the module, we will take a step back and look at the fundamentals of the quantum mechanical measurements process including the standard quantum limit, quantum non-demolition measurements as well as squeezed states and present examples from solid state physics for the field of quantum or cavity optomechanics as well as spin ensembles where these concepts are put to practice.
