A newly discovered trade-off in the way time-keeping devices operate on a fundamental level could set a hard limit on the performance of large-scale quantum computers, according to researchers from the Vienna University of Technology.
Summary: Measuring time is important when measuring a large number of quantum bits, and so there’s a constant race toward precision timekeeping. The article ends saying that component quality is more of a factor than the measurement of time (for now), but in the future potential advancements in quantum computing might be able to “buy time” in this arena and reduce errors in some future advancement.
