Delving into the Essence of Narrowband Single Photons

Single photons, the indivisible quanta of light, exhibit unique properties that distinguish them from their classical counterparts. Narrowband single photons, in particular, possess an exceptionally narrow spectral bandwidth, typically below 1 nanometer, and a well-defined polarization state. This combination of attributes endows them with unparalleled control and precision in manipulating light-matter interactions.

The generation of narrowband single photons is a meticulous process, often achieved through nonlinear optical techniques or spontaneous parametric down-conversion (SPDC). These methods exploit the nonlinear properties of certain materials to induce the spontaneous emission of photon pairs, one of which exhibits a narrow spectral profile.
