Google* is developing a quantum computer that it believes will outperform the world\u2019s top supercomputers, according to an August 31 New Scientist<\/em> article<\/a> and sourced to researchers contacted by the magazine.<\/p>\n

Google’s ambitious goal is to achieve “quantum supremacy”— which would be achieved when “quantum devices without error correction can perform a well-defined computational task beyond the capabilities of state-of-the-art classical computers,” as the authors of an arXiv<\/em> paper (open access) explain.<\/p>\n

The task in this case: simulate the behavior of a random arrangement of quantum circuits in a 48-qubit grid, which would require 2.252 petabytes of memory, almost double that of the top supercomputer in the world.<\/p>\n

To do that, Google plans to build a whopping 50 qubit computer. So far, Google has only announced a modest nine qubit computer<\/a>, but it has hired arXiv<\/em> paper co-author John M. Martinis at the University of California, Santa Barbara (see “Google partners with UC Santa Barbara team to build new superconductor-based quantum information processors<\/a>” on KurzweilAI<\/em>) to try.<\/p>\n

Success may prepare Google to construct something even bigger: a fully scalable machine,\u201d says\u00a0Ian Walmsley<\/a>\u00a0at the University of Oxford.<\/p>\n
