Teleportation, long a staple of science fiction, may be inching closer to reality thanks to breakthroughs in quantum mechanics. Since the 1990s, scientists have successfully teleported photons, and more recently, researchers have begun to explore the teleportation of electrons—a step that could revolutionize quantum computing and, potentially, the future of human travel. However, teleportation in reality does not function the way it does in Star Trek. Instead of moving physical matter instant...
