Characterization of SQUID-Based Null Detector for a Quantum Metrology Triangle Experiment

Juho Luomahaara, A. Kemppinen, P. Helistö +1 more

We present characterization of a null detector designed for an experiment aimed to close the quantum metrological triangle (QMT). The device is a SQUID amplifier equipped with a large winding-ratio planar input transformer improving the current resolution. We demonstrate equivalent input current noise down to 14 fA/Hz1/2. Furthermore, operation in a realistic environment of a dry dilution refrigerator hosting the QMT experiment is studied. We discuss particular challenges set by such system as the cryogenics introduces relatively large magnetic interference. We present data from measurements simulating the final QMT experiment and introduce the requirements for the averaging and bias reversal.

Experimental realisation of the quantum metrological triangle experiment at LNE: Set-up and first results

Barthelemy Steck, B. Chenaud, Nicolas Feltin +9 more

We describe the experimental set-up used at LNE for closing the quantum metrological triangle (QMT) experiment and also testing the quantization of a current generated by a single electron device. Our present device is an R-electron pump composed of 3 tunnel junctions. The influence of the pumping frequency on the noise and on the current stability is firstly investigated. Then preliminary results are given about the quantized current measured with the complete QMT set-up. A relative random uncertainty of a few parts in 106has been found for a 100 MHz pumping frequency.

A quantum current standard based on phase slip

C H Webster, S. P. Giblin, David Cox +2 more

We show that it is possible to fabricate a device, based on a superconducting nanowire, to demonstrate the existence of coherent quantum phase slip (QPS). If coherent QPS exists, this device will form the basis of a new type of quantum current standard capable of closing the metrological triangle.
