China claims new quantum computer solves task in microseconds that Frontier can't in years

USTC researchers say Jiuzhang 4.0 solved a Gaussian boson sampling task in microseconds.

They estimate the same task would take the El Capitan supercomputer about 10^42 years.

The photonic quantum computer reportedly improves on earlier versions in scale, photon handling, and efficiency.

The result adds momentum to China’s quantum supremacy claims in a race with major global rivals.
