On 3 December 2020 a University of Science and Technology of China team led by Pan Jianwei and Lu Chaoyang reported in Science that Jiuzhang performed Gaussian boson sampling with up to 76 detected photons in 200 seconds, estimating that the Sunway TaihuLight supercomputer would need 2.5 billion years. It was the second claimed quantum advantage after Google's 2019 Sycamore and the first with photons.

Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
