DARPA's military-grade 'quantum laser' will use entangled photons to outshine

Researchers are developing a military-grade "quantum laser" funded by DARPA, utilizing entangled photons to create a powerful laser beam capable of penetrating adverse weather conditions like fog. This prototype quantum photonic-dimer laser binds photons through quantum entanglement, enhancing precision and strength over long distances and in challenging environments. Unlike conventional lasers that rely on stimulating electrons in atoms, this quantum laser maintains coherence and performance by protecting entangled photons from atmospheric interference. The technology has potential applications in military operations such as surveillance and secure communications in harsh conditions. By linking photons through quantum entanglement, the laser's energy and stability are increased, enabling improved performance in extreme temperatures and foggy environments. This innovation could also impact quantum computing, telecommunications, and data transmission, offering faster and more secure methods. The research team behind this project aims to leverage entanglement properties for further innovative applications beyond laser technology.
