Spectral-Temporal Metrology with Tailored Quantum Measurements

Resultado final

We will derive the QCRB for the measurements laid out in WP1 considering the respective experimental systems of the partners and compare it to the classical CRB UNIROMA3 will then focus on the relevant example of measuring KramersKronig relations which are hard to measure classically see also T23
