Tiny red objects spotted by NASA’s James Webb Space Telescope (JWST) are offering scientists new insights into the origins of galaxies in the universe — and may represent an entirely new class of celestial object: a black hole swallowing massive amounts of matter and spitting out light. Using the firstContinue Reading
Physicists have developed a breakthrough concept in quantum encryption that makes private communication more secure over significantly longer distances, surpassing state-of-the-art technologies. For decades, experts believed such a technology upgrade required perfect optical hardware, namely, light sources that strictly emit one light particle (photon) at a time — something extremelyContinue Reading
Astronomers at the Center for Astrophysics | Harvard & Smithsonian have proposed a new explanation for some of the universe’s most puzzling early galaxies, nicknamed “little red dots.” In the study, published in The Astrophysical Journal Letters, Authors Fabio Pacucci and Abraham (Avi) Loeb suggest that these galaxies are theContinue Reading
Quantum dots – semiconductor nanostructures that can emit single photons on demand – are considered among the most promising sources for photonic quantum computing. However, every quantum dot is slightly different and may emit a slightly different color. This means that, to produce multi-photon states we cannot use multiple quantumContinue Reading
As the demand for innovative materials continues to grow — particularly in response to today’s technological and environmental challenges — research into nanomaterials is emerging as a strategic field. Among these materials, quantum dots are attracting particular attention due to their unique properties and wide range of applications. A teamContinue Reading
