QUANTUM COMPUTING WILL NEVER WORK BY JOHN RUSSELL
https://www.hpcwire.com/2018/11/27/quantum-computing-will-never-work/ Amid the gush of money and enthusiastic predictions being thrown at quantum computing comes a proposed cold shower in the form of an essay by physicist Mikhail Dyakonov published in IEEE Spectrum this month – The Case Against Quantum Computing . Whatever your view of QC’s prospects, Dyakonov’s commentary is worth a read. Error correction – or more accurately the inability to monitor variables and correct errors at the scale required – is the big stumbling block, he writes, but there is a good deal more to his piece . Sometimes it’s best to start with conclusions first. “To my mind, quantum computing researchers should still heed an admonition that IBM physicist Rolf Landauer made decades ago when the field heated up for the first time. He urged proponents of quantum computing to include in their publications a disclaimer along these lines: “This scheme, like all other schemes for quantum computation, relies o
