A new article published in Nature announces that a quantum computer is _managed to solve an operation in 36 microseconds_ which would normally have taken 9,000 years. Success, as can be read in the study published in the prestigious journal Nature, was achieved thanks to the Borealis programmable processor created by the Canadian-based startup Xanadu, which made use of some innovative techniques. The result was also applauded by the director of Quantum Computing of Amazon Web Services, according to whom this work opens the door to “important advances in understanding offered by quantum computations“. The approach used by Xanadu is diametrically different from the machines launched a few years ago by Google, which for the first time marked an overtaking against traditional computers. In fact, everyone will remember that in September 2019 Google announced that it had achieved quantum supremacy, among Intel’s general doubts. Xanadu was able to perform a calculation in 36 microseconds that would otherwise have taken at least 9,000 years, _working at room temperature_ (and therefore without the need to be cooled) and with a programmable photonic processor. The _problem solved is known as Gaussian Boson sampling_ and can be calculated by conventional computers up to certain parameters. The article is in Italian Paper: https://www.nature.com/articles/s41586-022-04725-x A quantum computer attains computational advantage when outperforming the best classical computers running the best-known algorithms on well-defined tasks. No photonic machine offering programmability over all its quantum gates has demonstrated quantum computational advantage: previous machines1,2 were largely restricted to static gate sequences. Earlier photonic demonstrations were also vulnerable to spoofing3, in which classical heuristics produce samples, without direct simulation, lying closer to the ideal distribution than do samples from the quantum hardware. Here we report quantum computational advantage using Borealis, a photonic processor offering dynamic programmability on all gates implemented. We carry out Gaussian boson sampling4 (GBS) on 216 squeezed modes entangled with three-dimensional connectivity5, using a time-multiplexed and photon-number-resolving architecture. On average, it would take more than 9,000 years for the best available algorithms and supercomputers to produce, using exact methods, a single sample from the programmed distribution, whereas Borealis requires only 36 μs. This runtime advantage is over 50 million times as extreme as that reported from earlier photonic machines. Ours constitutes a very large GBS experiment, registering events with up to 219 photons and a mean photon number of 125. This work is a critical milestone on the path to a practical quantum computer, validating key technological features of photonics as a platform for this goal.
