摘要：

量子计量基准与传统的计量基准相比较,具有准确度高、可在多个地点复现等一系列显著优点,近40年来得到了很快的发展。目前,长度、时间、电学等方面的量子基准已逐步建立,测量准确度提高了几个数量级。在新世纪中,量子计量基准将得到进一步的发展和完善。

Abstract: In comparison with the traditional measurement standards,the quantum measurement standards have a series of outstanding advantages, such as its high accuracy, reproducibility at different laboratories, etc..Therefore, the quantum measurement standards developed rapidly in the passed forty years.At present, the quantum standards for length, time, electrical quantities have been established and the measurement accuracy was improved by several magnitudes.In the new century, the quantum measurement standards will be developed and improved further.

Keywords: Quantum measurement standards; Energy level; Fundamental physical constants
