もつれた光子を生成するためのシステム及び方法

Resumen de: CN121444010A

Systems and methods for generating entangled photons are presented. The systems and methods generally utilize dopant molecules contained in a host material within a microcavity. The dopant molecules are generally associated with a ground state triplet (GST) electron manifold. When the dopant molecules are subjected to light, the electron state of the dopant molecules is excited to an excited triplet (EST) electron manifold. The electronic state then decays via a transition path that includes a zero phonon line (ZPL) electron transition. In the presence of the microcavity, the decay rate of electron transition along the ZPL is greatly enhanced. Thus, when the dopant molecules decay from the EST electron manifold to the GST electron manifold they emit photons having a nearly pure optical state (e.g., nearly pure wavelength and optical polarization). Thus, the optical state of the emitted photons correlates with the electronic state of the dopant molecules.
