Quantum teleportation could reduce photon loss in long-distance communications
Quantum technologies, which leverage the principles of quantum mechanics, have been found to outperform their classical counterparts on specific tasks. Among other things, past studies have highlighted the potential of quantum systems that can enable long-distance communication, using photons (i.e., particles of light) to carry quantum information. Despite their promise, quantum communication systems are often […] The post Quantum teleportation …
Photons are constantly lost on the way through fiber optic cables or free space, and the further the distance, the greater the losses. At long distances, only a tiny fraction of the emitted light particles often survive the journey to the receiver. This loss complicates applications such as seamless Bell tests or listening-proof quantum key distribution considerably and slows down the development of global quantum networks for decades. A team of…
