Modern imaging technologies are widely based on classical principles of light or
electromagnetic wave propagation. They can be remarkably sophisticated, with recent …

Interference, which refers to the phenomenon associated with the superposition of waves,
has played a crucial role in the advancement of physics and finds a wide range of …

Abstract Hong–Ou–Mandel (HOM) interference—the bunching of indistinguishable photons
at a beamsplitter—is a staple of quantum optics and lies at the heart of many quantum …

Entangled biphoton sources exhibit nonclassical characteristics and have been applied to
imaging techniques such as ghost imaging, quantum holography, and quantum optical …

As first demonstrated by Hanbury Brown and Twiss, it is possible to observe interference
between independent light sources by measuring correlations in their intensities rather than …

Quantum entanglement and squeezing have significantly improved phase estimation and
imaging in interferometric settings beyond the classical limits. However, for a wide class of …

Quantitative phase imaging provides a way to image transparent objects, such as biological
cells, and measure their thickness. We report on a phase-imaging method that achieves …

Pixelation occurs in many imaging systems and limits the spatial resolution of the acquired
images. This effect is notably present in quantum imaging experiments with correlated …

Imaging based on the induced coherence effect makes use of photon pairs to obtain
information of an object without detecting the light that probes it. While one photon …

Measurements of photon temporal correlations have been the mainstay of experiments in
quantum optics. Over the past several decades, advancements in detector technologies …
