This experiment shows a scalable path to quantum networks.
In a breakthrough that blurs the line between science fiction and reality, scientists at the University of Oxford have successfully demonstrated quantum teleportation, marking the first instance of distributed quantum computing.
The experiment involved teleporting quantum states between two separate processors using photons. A photonic network interface connected the modules, allowing them to function as a single computer. According to Oxford researchers, it was “the first instance of distributed quantum computing,” bridging decades of theory with present-day technology.
The team achieved this by entangling particles across two ion modules separated by two meters. With an 86% fidelity rate, they were able to run a Grover algorithm with 71% efficiency. Unlike conventional methods, this avoided destroying fragile qubit states, instead reconstructing them securely at the destination.
Experts say the milestone could revolutionize computing by linking smaller quantum processors into networks that operate as one powerful supercomputer, paving the way for breakthroughs in cryptography, simulations, and physics.
