The Globe and Mail reports in its Friday edition that Nord Quantique chief executive officer Julien Camirand Lemyre has been focused on tackling a major challenge in commercial quantum computing: error rates. The Globe's Ivan Semeniuk writes that on Thursday, the company announced it has successfully implemented its own quantum device to encode a form of error detection for the first time. Bigger players, including Google, Microsoft and Amazon, are working on the same problem as they seek to advance their own quantum systems. What is different about Nord Quantique is that the hardware doing the checking is the same hardware doing the calculating. The experimental result suggests that larger, commercially relevant quantum computers can be constructed from similar components. If so, those computers might occupy only a modest amount of space -- something that would fit inside a standard data centre rather than a football-field size complex that some fear will be needed to get other types of quantum systems to run reliably. The company's announcement, together with an accompanying technical paper, is the latest step in what has become an industry-wide push to tackle error correction, also called fault tolerance.
