Quantum dot emitter delivers near-identical telecom photons at 40 million/ second, delivering speed/ quality for the quantum internet

"entanglement swapping/ secure data transfer requires photons from different sources be indistinguishable so can interfere with each other, but at telecom wavelengths quantum dots often fluctuate color/ emit too slowly, overcome using indium arsenide quantum dots embedded in circular Bragg grating bullseye resonator... quantum repeaters working at speeds rivaling 5G or 6G... photons travelling through millions of miles of existing fiber-optic cable/ minimal signal loss... compatible manufacturing, goal: single chip"
