Missions

The combination of analogue and digital superconductor electronics based on the same fabrication technology leads to mixed-signal circuits that can be used in a range of applications for which a fast and efficient processing can be performed directly on-chip at cryogenic temperature, close to the sensors. This technology is interesting when either high energy efficiency, high bandwidth or on-chip control and readout of complex arrays of quantum-accurate sensors is required. Sensors can be of magnetic type, like Superconducting Quantum Interference Devices (SQUIDs), or of microwave types like Kinetic Inductance Detectors (KIDs), THz quantum-accurate Superconductor-Insulator-Superconductor (SIS) heterodyne sensors, Transition Edge Sensors (TES), used for instance in radio-astronomy at the focal point of ground-, balloon- and space-based telescopes. This technology can also be used to simplify the readout and control of Quantum Bits (Qu-bits) for quantum computing applications, or to detect single photons based on Superconducting Nanowire Single-Photon Detector (SNSPDs), also used for quantum cryptography.
In this context superconductor electronics activity conducted in close collaboration with several laboratories and research centers, is focused on:
• the study, design and experimental characterization of high and low critical temperature digital and analogue superconductor circuits: influence of magnetic field, temperature, THz frequency behavior, study of new devices and principles ;
• the development of demonstrators based on superconductor mixed-signal circuits for applications in space telecommunications and in geophysics ;
• the development of open-source software tools for the design and characterization of complex digital circuits, analogue systems (including THz superconducting sensors) and mixed-signal circuits.

In the frame of the ColdFlux project developed between groups located in the United States of America, South Africa, Japan and France, we study the electrical, thermal, magnetic and microwave properties of superconducting digital circuits. The work is focused on the development of a Multiphysics approach to predict the behavior of circuits and build advanced SPICE-based models as well as dynamic libraries and TCAD modules to help the designer.

Activities

The main objective of the work is to :
- transform a set of scientific softwares, either already available in the laboratory or open-source, in Python and/or C++ language and to adapt them to our specific needs ;
- integrate them in a generic platform that is being developed in parallel ;
- develop new software to handle several needs regarding the project.
In this context, close interaction with other members of the team will be necessary to define the specifications from the scientific expectations. All software must be multiplatform : Windows 10, Linux CentOS8 and MacOSX

Skills

Excellent skills are expected in computer science with C/C++ and Python coding on the Qt multiplatform environment, and in electronics. A knowledge of Fortran and MatLab-based languages is an advantage. A set of other tools based on Matlab, Layout Editor, Comsol, Inductex, JSIM and JoSIM will be used. Knowledge of open-source software platforms like GitHub is necessary.

Work Context

The Laboratory of Microwave and Characterization (IMEP-LAHC, CNRS UMR 5130) of Université Savoie Mont Blanc located in the French Alps area develops activities about superconductor electronics that comprise the development of analogue sensors using the properties of quantum mechanics to reach ultimate sensitivity, and the studies of ultrafast energy-efficient superconducting digital circuits that can work with clock frequencies of several tens of GHz, based on the Single-Flux Quantum (SFQ) technology.
The context of this position is international with strong interactions required with US, South African, Japanese, Turkish and Ukrainian groups. A good knowledge of the English language is required. The writing of monthly progress reports is expected. Locally the candidate will need to interact within a team of four to six people including post-doctoral researchers, PhD students and master students.
