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

Researchers are developing a new, military-grade "quantum laser" that can cut through fog and operate across long distances.
The U.S. Defense Advanced Research Projects Agency (DARPA) has awarded a $1 million grant to scientists building a prototype "quantum photonic-dimer laser" that uses quantum entanglement to "glue" light particles together and generate a highly concentrated laser beam.
Lasers play a crucial role in military operations and are used in everything from satellite communications and targeting technology to mapping and tracking systems like lidar (light detection and ranging).
