Quantum enhanced imaging

Exploiting the quantum properties of entangled photon-pairs allows the limits of classical imaging to be surpassed, whether that may be imaging beyond the shot-noise limit or the classical limits of resolution. Full-field imaging of quantum correlations has recently become possible as a result of single-photon sensitive detector arrays thereby offering a substantial reduction in the time required to acquire an image when compared to the scanning-fibre techniques previously employed. The work presented in this thesis seeks to utilise the spatial correlations between entangled photon-pairs to improve quantum imaging techniques such that quantum-enhanced imaging may be applied in real-world applications. Such applications included in this work include contrast-enhanced and resolution-enhanced imaging which may find applications in quantum enhanced microscopy, and quantum Lidar
