Researchers from Harvard and MIT have pioneered a device that could improve quantum communication and may be the key to developing a quantum internet, according to an article published Monday in the scientific journal Nature.
Quantum signals lose information when traveling over long distances. To solve this problem, the researchers’ new technology catches and stores quantum bits — known as qubits — thus preventing information loss. The physicists hope this breakthrough will open the door to a quantum internet that can communicate unhackable messages.
“This is the first system-level demonstration, combining major advances in nanofabrication, photonics and quantum control, that shows a clear quantum advantage to communicating information using quantum repeater nodes,” Mikhail D. Lukin — a Harvard physics professor who lead the research team — said in a press release published Monday. “We look forward to starting to explore new, unique applications using these techniques.”
