Documents, reports (2)

Quantified limits and benefits

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

TF projectors for DV and CV systems

Implementation and tomography of projectors onto TF superposition states in both continuous and discrete variable systems

Open Research Data Pilot (1)

Data Management Plan

A data management plan will be set up in order to balance openness and protection of scientific information
