Assessing data postprocessing for quantum estimation

Understand

Quantum sensors are among the most promising quantum technologies, allowing to attain the ultimate precision limit for parameter estimation.

• In order to achieve this, it is required to fully control and optimize what constitutes the hardware part of the sensors, i.e.
• the preparation of the probe states and the correct choice of the measurements to be performed.
• However careful considerations must be drawn also for the software components: a strategy must be employed to find a so-called optimal estimator.
