Scientists at Columbia University have created a molecular sodium-cesium Bose-Einstein condensate (BEC) that is dipolar and lasts for two seconds, opening new possibilities for exploring exotic states of matter and quantum physics applications. This breakthrough was achieved using microwave fields to control interactions at ultracold temperatures near absolute zero, potentially leading to advances in quantum chemistry and the study of novel quantum phases.
Researchers have achieved room temperature operation of a germanium-on-silicon single-photon avalanche diode (SPAD), a key component in photonics and quantum applications. This advancement is significant as it enables the practical integration of SPADs into various technologies, such as quantum communication and imaging systems, without the need for cryogenic cooling. The development opens up new possibilities for high-performance photon detection and imaging at room temperature, paving the way for more widespread and accessible applications in the field of photonics.
