New Low-Cost, Efficient Single-Photon Source for Powering Future Quantum Internet

With the rise of quantum computers, the security of our existing communication systems is at risk. Quantum computers will be able to break many of the encryption methods used in current communication systems. To counter this, scientists are developing quantum communication systems, which utilize quantum mechanics to offer stronger security. A crucial building block of these systems is a single-photon source: a device that generates only one ligh…

Tokyo University of Science Researchers Develop Efficient All-Fiber Single-Photon Source

A research team led by Associate Professor Kaoru Sanaka from the Tokyo University of Science (TUS) has developed a highly efficient fiber-coupled single-photon source. This new method generates single photons directly inside an optical fiber by selectively exciting a single, isolated rare-earth (RE) ion, overcoming high transmission loss issues common in conventional quantum communication systems. [...] The post Tokyo University of Science Resea…
