The quantum Hall resistor standard traces the unit value of resistance directly to the fundamental physical constants, which fundamentally solves the problem that the classical physical resistor standard is susceptible to environmental factors (e.g. temperature, altitude, electromagnetism, etc.), and it has made a significant contribution to the overall enhancement of resistor metrology capability. This paper reviews the research status of GaAs, graphene, quantum anomalous Hall effect based quantum Hall resistor standard, as well as decimal quantum Hall resistor standard, et al. And describes the bottlenecks faced by the research of quantum Hall resistor standard. After the literature research, it is found that the GaAs-based quantized Hall resistor standard has been listed as the resistance benchmark of many countries, and the development of lightweight quantized Hall resistor standard technology based on new materials or physical effects (e.g. graphene materials, quantum anomalous Hall effect) has become a hot spot in this field. Through the research and reflection on the existing research results, this paper looks forward to the future development direction of the quantized Hall resistor standard technology, aiming to provide useful reference for the in-depth research on quantized Hall resistor standard.
