Experimental witnessing of the quantum channel capacity in the presence of correlated noise

2020 · Physical Review A

The authors demonstrate an experimental approach to detect lower bounds to the quantum capacity of two-qubit communication channels with correlated noise realized with the polarization degrees of freedom of two photons. The major advantage of …

Fisher information susceptibility for multiparameter quantum estimation

2023 · arXiv (Cornell University)

Noise affects the performance of quantum technologies, hence the importance of elaborating operative figures of merit that can capture its impact in exact terms. In quantum metrology, the introduction of the Fisher information measurement noise …
