Photonic Quantum Computer Reportedly Demonstrates Quantum Advantage

Facebook Twitter LinkedIn Email Comments
A team of physicists in China claimed it has demonstrated a “quantum advantage,” introducing a light-driven quantum computer capable of performing a computation that would take a classic supercomputer an estimated 600 million years to resolve. The team’s photonic quantum computer ultimately took several minutes to complete the boson sampling problem — a computation originally devised in 2011. The result follows Google’s 2019 announcement that its device, dubbed Sycamore, was the first to achieve a clear quantum advantage. Where chip-based superconducting...Read full article
