04【ScientificAmerican】Light-based Quantum Computer Exceeds Fastest Classical Supercomputers
For the first time, a quantum computer made from photons—particles of light—has outperformed even the fastest classical supercomputers.Physicists led by Chao-Yang Lu and Jian-Wei Pan of the University of Science and Technology of China (USTC) in Shanghai performed a technique called Gaussian boson sampling with their quantum computer, named Jiŭzhāng. The result,reported in the journalScienc...

04【Newscientist】A quantum computer that measures light has achieved quantum supremacy
Lasers are used in a new type of quantum computing called boson samplingIM_VISUALS/ShutterstockA new type of quantum computing called boson sampling is capable of calculations that no classical computer could accomplish in any reasonable amount of time. This is the second time a quantum algorithm has claimed to achieve this feat, known as quantum supremacy, after Google made a claim of quantum ...

04【Nature】Physicists in China challenge Google’s ‘quantum advantage’
This photonic computer performed in 200 seconds a calculation that on an ordinary supercomputer would take 2.5 billion years to complete.Credit: Hansen ZhongA team in China claims to have made the first definitive demonstration of ‘quantum advantage’ — exploiting the counter-intuitive workings of quantum mechanics to perform computations that would be prohibitively slow on classical computer...

04【PhysicsWorld】Quantum advantage demonstrated using Gaussian boson sampling
Quantum advantage: the Gaussian boson sampling experiment at the University of Science and Technology of China. (Courtesy: Chao-Yang Lu)A optical circuit has performed a quantum computation called “Gaussian boson sampling” (GBS) 100 trillion times faster than a supercomputer could, according to researchers in China. This feat was achieved by Jian-Wei Pan and Chao-Yang Lu at the University of ...

04【Scott Aaronson】Quantum supremacy, now with BosonSampling
A group led byJianwei Pan, based mainly in Hefei and Shanghai, announced today that itachieved BosonSampling with 40-70 detected photons—up to and beyond the limit where a classical supercomputer could feasibly verify the results. (Technically, they achieved a variant called Gaussian BosonSampling: a generalization of what I calledScattershot BosonSamplingin a 2013 post on this blog.)For more,...
