A ‘Teleportation’ Breakthrough for Quantum Computing Is Here

Wired  

Quantum computing has enormous potential, but it faces a scalability problem. Scientists are working on a solution that sounds like something out of a science fiction series: connecting remote cores to each other through “quantum teleportation” to create even more powerful machines. The team, led by graduate student Dougal Main, managed to get distant systems to interact with each other and share logic gates using quantum entanglement. "This breakthrough allows us to effectively ‘connect’ different quantum processors into a single, fully connected quantum computer," Main recounted. Willow, Google's quantum chip, recently solved a benchmark task called random circuit sampling in five minutes; it would have taken up to 10 quadrillion years for a conventional supercomputer to get the same result.
