Enhancing optical microscopy with quantum entanglement

Drawing on the unique properties of entangled photons, quantum approaches can overcome the limitations of classical methods, enhance spatial resolution and reduce stray light and shot noise.

Quantum imaging of biological organisms using hyperentangled photon pairs

We introduce quantum imaging by coincidence from entanglement (ICE) that overcomes challenges faced by existing quantum imaging methods. ICE utilizes hyperentangled photon pairs to achieve higher signal-to-noise ratios, greater resolvable pixel …

Super-resolution quantum microscopy at the Heisenberg limit

We introduce quantum microscopy by coincidence (QMC) featuring balanced pathlengths, which facilitates super-resolution imaging at the Heisenberg limit, drastically boosting speed and contrast-to-noise ratio (CNR) compared to existing wide-field …

Experimental full-domain mapping of quantum correlation in Clauser-Horne-Shimony-Holt scenarios

Quantum correlation is critical in quantum information applications, and numerous inequalities have been established to quantify the non-classical correlations such as the Bell nonlocality and quantum steering. We introduce an experimental method to …

Quantum imaging of biological organisms through spatial and polarization entanglement

Quantum imaging holds potential benefits over classical imaging but has faced challenges such as poor signal-to-noise ratios, low resolvable pixel counts, difficulty in imaging biological organisms, and inability to quantify full birefringence …

Quantum microscopy of cells at the Heisenberg limit

Entangled biphoton sources exhibit nonclassical characteristics and have been applied to imaging techniques such as ghost imaging, quantum holography, and quantum optical coherence tomography. The development of wide-field quantum imaging to date has …

Experimental full-domain mapping of quantum correlation in Clauser-Horne-Shimony-Holt scenarios

Quantum correlation between two parties serves as a useful resource in the surging applications of quantum information. The Bell nonlocality and quantum steering have been proposed to describe nonclassical correlations against local-hidden-variable …
