Project description
Quantum metrology could enable a new definition of the ampere
For millennia, people have been developing increasingly accurate ways to define standardised units of measurement for parameters such as time, distance and weight. While we typically think of quantum clocks and time when quantum metrology is mentioned, the field leverages quantum effects to enhance the precision of all sorts of measurements. With the support of the Marie Skłodowska-Curie Actions programme, the QMET project is planning to develop an approach to high-precision microwave measurements that will pave the way for a redefinition of the ampere, our unit of electrical current, with quantum precision.
Objective
The standard definition of the Ampere can be obtained exploiting the dual counterpart of the Josephson effect, namely voltage Bloch Oscillations (vBO). A way to measure them consists in embedding a largely non-linear Josephson junction in a high impedance environment, irradiate it with a microwave pump, and observe discrete DC current steps. The QMET (Quantum Metrology Electrical Triangle) action tackles this objective by leveraging the researcher demonstrated ability of performing precision microwave measurements devising novel apparatuses and the mastering of the host group in the design and fabrication of high-impedance superconducting circuits. Such result would provide a leap in quantum metrology and paves the way to the redefinition of the ampere using only fundamental constants.
