• Physicists May Have Found a Hard Limit on The Performance of Large Quantum Computers

  03-12-2023 21:59 via science.slashdot.org
  For circuit-based quantum computations, the achievable circuit complexity is limited by the quality of timekeeping. That's according to a new analysis published in the journal Physical Review Letters exploring "the effect of imperfect timekeeping on controlled quantum dynamics."
  An announcement from the Vienna University of Technology explains its significance. "The research team was able to show that since no clock has an infinite amount of energy available (or generates an infinite amount of e

  A pull request has been merged to fix a data corruption issue in OpenZFS (the open-source implementation of the ZFS file system and volume manager). "OpenZFS 2.2.2 and 2.1.14 released with fix in place," reports a Thursday comment on GitHub.Earlier this week, jd (Slashdot reader #1,658) wrote: All versions of OpenZFS 2.2 suffer from a defect that can corrupt the data. Attempts to mitigate the bug have reduced the likelihood of it occurring, but so far nobody has been able to pinpoint what is goi
