Researchers involved in the SUPERGALAX project

The RUB partner group (Prof. Ilya Eremin (PI) and Dr. Mikhail Fistul) has a long established expertise in a theoretical study of coherent quantum phenomena in various metallic, magnetic, semiconducting and superconducting nanostructures under equilibrium or non-equilibrium conditions. Last several years the RUB group has also concentrated on the number of projects related to the analysis of the proximity effects in heterostructures containing magnets and superconductors, analyzed the properties of unconventional superconductors, studied unconventional methods of quantum computing, i.e. Majorana fermions or skyrmions.

The specific objectives of our project are as follows:

1. Development of a single microwave photon detector based on moderate size networks of interacting superconducting qubits utilizing both transmons and flux qubits.
2. Development of the Parametric Down Conversion (PDC) microwave photon source based on the Traveling Wave Josephson Parametric Amplifier (TW-JPA) with a clock frequency of few kHz
3. Integration of the PDC MW photon source with two single photon SQN detectors in a common setup to develop an heralded single photon source and to carry out the test of the detectors at single MW photons.
4. Installation of the single photon SQN detector integrated with the single photon source as a calibration element in a He free refrigerator of the QUAX Collaboration.
5. Experimental study of feasibility of the single microwave photon SQN detector for the “haloscope” type of axion searching using the axion conversion in a magnetic field.
