This electron micrograph image of the single-photon sources developed at UCSB shows the etched trenches that leave behind large, 20-micron cavities. The different geometries influence the shape of the confined light field inside the cavity and thus dictate the polarization of the emitted photons. Image credit: Stefan Strauf, et al.

Scientists have achieved a major advance in developing a single-photon light source, bringing quantum applications such as quantum computing and quantum cryptography closer to reality.
