Researchers at University of Bristol Demonstrate Chip-to-Chip Quantum Teleportation

(Sci-News) A research team led by University of Bristol scientists has successfully demonstrated quantum teleportation of information between two programmable micrometer-scale silicon chips. The team’s work, published in the journal Nature Physics, lays the groundwork for large-scale integrated photonic quantum technologies for communications and computations.
Teleportation is not only useful for quantum communication but is a fundamental building-block of optical quantum computing. Establishing an entangled communication link between two chips in the lab however has proven to be highly challenging.
“We were able to demonstrate a high-quality entanglement link across two chips in the lab, where photons on either chip share a single quantum state,” said study first author Dr. Dan Llewellyn, a researcher in the Quantum Engineering Technology Labs at the University of Bristol.
