A new publication from Opto-Electronic Science; DOI 10.29026/oes.2024.230029 discusses unraveling the efficiency losses and improving methods in quantum dot-based infrared up-conversion photodetectors ...

Quantum information can be carried in particles of light called photons. Single photon emitters that emit precisely one photon at a time are important components for many quantum technologies, ...

Controlled generation of single-photon emitters in silicon (red) by broad-beam implantation of ions (blue) through a lithographically defined mask (left) and by a scanned focused ion beam (right).

Optical quantum computers are gaining attention as a next-generation computing technology with high speed and scalability. However, accurately characterizing complex optical processes, where multiple ...

"In the past, the best that was achieved is 1 in 100 million. Our achievement is realizing a factor of 10,000 increase conversion efficiency to 1 in 10,000 with a nanophotonic platform." The ...
