Quantum-enhanced imaging
Quantum correlations can improve imaging under specific dose and noise constraints.
$$\mathrm{SNR}=\frac{\langle S\rangle}{\sqrt{\mathrm{Var}(S)}}$$
Physical intuition
Quantum correlations can improve imaging under specific dose and noise constraints.
Deep dive: physical mechanism
Correlated photons or squeezed illumination can reduce measurement noise for selected observables while preserving image formation.
What is measured experimentally?
Compare image contrast and SNR at equal detected photon dose.
Assumptions, noise and limitations
Loss, sample damage and detector noise can erase an advantage.
Research and simulation exercise
Simulate low-light imaging with classical and correlated count statistics.
