“Quantum sensing of axion dark matter with a hybrid magnon-photon-superconducting circuit platform”

Biography

The research of Takis Kontos is mainly based on the implementation of hybrid quantum circuits, aiming to reveal new states of matter or to exploit quantum mechanical properties of circuits. During his thesis at CSNSM, Orsay, France, he studied the interplay of superconductivity and ferromagnetism in multilayers of superconductors and ferromagnetic alloys together with Marco Aprili and Jérôme Lesueur. He moved as a postdoctoral researcher to the University of Basel, Switzerland, in the group of Prof. Christian Schönenberger, where he studied spin transport in carbon nanotubes. Since 2005, he has been permanent CNRS researcher at LPENS, Ecole Normale Supérieure, first as a research associate and, since 2013, as a research director. In collaboration with Audrey Cottet for the theoretical aspects, his research has focused on the implementation of a circuit quantum electrodynamics architecture with carbon nanotubes. He could shed new light on fundamental aspects of condensed matter such as the Kondo effect. He could also develop a synthetic spin-photon interface for single spins trapped in carbon nanotubes. The latter work is at the basis of the technology used by the “quantum” start-up C12 Quantum electronics, which Takis Kontos co-founded in 2020. Takis Kontos is now focusing on the use of quantum sensing techniques with circuits in order to test dark matter paradigms such as axions or to measure other cosmological signals. He is also a research fellow at the Institute of Astrophysics-FORTH, Crete, Greece.
