摘要：
In this short review article we will discuss the implications of quantum physics on measurement uncertainties that will be illustrated by concrete examples from quantum metrology. The article starts with a discussion on the differences in possible measurement outcomes between classical physics and quantum physics. Then we will present examples from quantum transport which define the so called metrological triangle-quantum Hall effect, Josephson effect and quantized charge pumping. Non-classical quantum mechanical properties such as entanglement or squeezed light will be explained and their positive consequences on measurement uncertainties will be given. The article closes with a conclusion, where also new directions for quantized transport properties will be highlighted.
