Photofluorochromic water-dispersible nanoparticles for single-photon-absorption upconversion cell imaging

Nanotechnology, 2021
Abstract Photofluorochromic diarylethene (DAE) molecules have been widely investigated due to their excellent fatigue resistance and thermal stability. However, the poor water solubility of DAEs limits their biological applications to some extent.

Single-photon sources using two-photon absorption

SPIE Proceedings, 2007
Although two-photon absorption (TPA) is a nonlinear optical process, it is not typically considered a fundamental resource for optical quantum information processing (QIP). We have recently shown that TPA and the quantum Zeno effect can be used to make deterministic quantum logic devices (Zeno gates) from an otherwise linear optical system.
