Entanglement Enhanced Sensing with Qubits affected by non-Markovian Dephasing
The study investigates how entanglement can improve sensing sensitivity in Ramsey spectroscopy when qubits are subjected to correlated, non-Markovian noise. While standard methods assume uncorrelated noise, this work shows that entangled probes can achieve better scaling of sensitivity with more probes than separable states under specific temporal and spatial noise correlations.
