D-Wave Systems, which in 2011 became the first company to bring a working quantum computer to market, is diversifying beyond the quantum annealing approach that has been its bread and butter and entering the superconducting gate-model sector that will put it in direct competition with IBM. The Canadian company announced at its Qubits conference that it plans to make its first gate model commercially available in 2023 or 2024. While quantum annealing works well for certain specialized functions, gate-model quantum computing is considered more broadly applicable, in areas like materials science and pharmaceutical research.

China’s top quantum research group said its Jiuzhang quantum computer produced results in minutes that would take 2+ billion years by the world’s No. 3 powerful supercomputer. That exceeds Google’s prototype quantum computer which, last year, came up with a result in minutes that it estimated would take a supercomputer 10,000 years. The two quantum computers work differently: China’s University of Science and Technology’s computer manipulates photons, whereas Google’s builds quantum circuits via super-cold superconducting metal.
