A trio of separate research teams from three different continents published individual papers indicating similar quantum computing breakthroughs yesterday.Maybe it’s the whole concept of entanglement but for a long time it’s felt like we were suspended in a state where functional quantum machines were both “right around the corner” and “decades or more away.” The likes of IBM Microsoft D-Wave and Google putting hybrid quantum systems on the cloud coupled with the latter’s amazing time crystal breakthrough have made 2018-2021 the opening years of what promises to be a golden age for quantum computing.
Despite this amazing progress there are still holdouts who believe we’ll never have a truly useful fully-functional qubit-based quantum computing system.The three new papers published yesterday (here here and here) should go a long way towards shutting those critics up because each of them manages to address the error-correction problem in quantum computing by essentially going back to the drawing board.The result is that each team was able to build a distinct silicon-based two-qubit quantum computing system capable of operating with greater than 99% accuracy.
That’s pretty cool but dozens of quantum research centers including IBM’s Google’s and Microsoft’s have all developed functional quantum gate systems with dozens or even hundreds of qubits.IBM and Google for example both claim they’ve reached “quantum advantage ” or the point where their quantum computing systems can do things that no regular classical computing system could.The new research hopes to alleviate that by creating a new way to handle qubit operations thus allowing gate-based quantum computer systems to scale.In a press release from the University of New South Wales Mateusz Madzik a lead author on the Australian team’s research paper described how entangling an electron with the nuclei of two phosphorous atoms allowed them to control them as qubits without losing information.But now you have
