LANL Study Paves Way to Light-Based Quantum Computing, QKD and Other Quantum Tech

By IQT News posted 06 Jun 2019

(LosAlamosReporter) Efforts to create reliable light-based quantum computing, quantum key distribution for cybersecurity, and other technologies got a boost from a new study at Los Alamos National Laboratory that demonstrated an innovative method for creating thin films to control the emission of single photons.
“Efficiently controlling certain thin-film materials so they emit single photons at precise locations—what’s known as deterministic quantum emission—paves the way for beyond-lab-scale quantum materials,” said Michael Pettes, a Los Alamos National Laboratory materials scientist and leader of the multi-institution research team.
“While more research is needed to fully understand the role of mechanical deformation in creating these quantum emission sites, we may enable a route to control quantum optical properties by using strain,” Pettes said. “These single-photon sources form the basis for photonics-based, all-optical quantum computing schemes.”
