Borealis is the second device to demonstrate quantum advantage in boson sampling. The first is a machine called Jiuzhang, created by researchers at the University of Science and Technology of China.

The researchers behind a quantum computer that encodes data in pulses of light have connected it to the Internet and made it available for public use.

The Borealis system developed by scientists at Canada's Xanadu Quantum Technologies and the U.S. National Institute of Standards and Technology taps photons routed through fiber-optic loops to address the challenge of boson sampling.

The problem involves quantifying the properties of a large group of entangled photons separated by beam splitters, which Borealis can accomplish in 36 microseconds, while the best supercomputer would take at least 9,000 years.

The system directly measures the behavior of up to 216 entangled photons to compute the answer.

"Borealis is the first machine capable of quantum computational advantage made publicly available to anyone with an Internet connection," said Xanadu's Jonathan Lavoie.
