The article examines the features of major international and national standardization systems, metrology and certification as a means to improve the competitiveness of products and services.
The paper deals with the issues of measurement traceability based on uncertainty of measurements as an integral part of specific measurement technologies based of new information system. A short review of papers devoted to measurement traceability problem in modern conditions is described. It is proposed to further expand a concept of "special technical means" in carrying out of measurements. Example of the information system of the measurement traceability support is highlighted.
Quantum fluctuations in quasi-one-dimensional superconducting channels leading to spontaneous changes of the phase of the order parameter by 2, alternatively called quantum phase slips (QPS), manifest themselves as the finite resistance well below the critical temperature of thin superconducting nanowires and the suppression of persistent currents in tiny superconducting nanorings. Here we report the experimental evidence that in a current-biased superconducting nanowire the same QPS process is responsible for the insulating state—the Coulomb blockade. When exposed to rf radiation, the internal Bloch oscillations can be synchronized with the external rf drive leading to formation of quantized current steps on the I-V characteristic. The effects originate from the fundamental quantum duality of a Josephson junction and a superconducting nanowire governed by QPS—the QPS junction
