Sensitivity, Quanta and Precision: A tour through application of quantum enhanced measurements
Prof. Dr. Jörg Wrachtrup (3. Physikalisches Institut, Universität Stuttgart)

Precision measurements are a classical real of quantum physics. Using quantum standards and dedicated quantum control, unprecedented accuracy in e.g. time keeping has been achieved. Yet there is little application of quantum precision measurements in other areas like e.g. material science or medical diagnostics. With the rise of well-controlled solid-state systems, which allow for precision control and readout of quantum states, such applications come within reach. The talk will describe the use of diamond defects for precision sensing of various parameters like magnetic and electric fields or temperature and pressure. Owing to the compact nature of the sensors, unprecedented spatial resolution can be combined with high sensitivity which is even further enhanced using multi particle states in e.g. quantum memories.
