• Brief description of your expertise / expertise you are looking for:

  Our primary focus is on delivering quantum transduction solutions for quantum network applications and entangled-photon-based quantum sensing. Specifically, we currently concentrate on the studies of novel Hybrid Quantum Systems, based on the use of electron spin materials, such as optically active rare-earth doped crystals and magnon quantum materials. These interdisciplinary studies leverage combined efforts in the physics of microwaves, optics, and materials. We are also interested in the proposals on quantum sensing (e.g. use of NV centers in diamond as highly sensitive magnetic field sensors) as well as in basic science investigations of quantum materials. As regards the field of quantum computation, our expertise in MW techniques allows us to contribute efficiently to the development of cryogenic MW components, both passive and active ones. Research infrastructure of our group: Bluefors dilution refrigerator system (10 mK) with a superconducting vector magnet, free-optic/fiber optical access for visible and infrared spectroscopy, and microwave measurements up to 40 GHz. An additional cryogenic system (Attocube 1.4 K) offers similar optical and microwave measurement capabilities. This cryogenic cluster also includes a bunch of MW and optical characterization devices, including the Keysight PNA-X series VNA, ASG, AWG, High-bandwidth Digital Oscilloscope, and optical components and devices. Beyond our core lab, the QSTL team enjoys exclusive access to advanced research infrastructure, including: thin film fabrication & nanofabrication (magnetron/MBE/PLD deposition), optical lithography, versatile structural/magnetic/magneto-optical & electronic characterization (XRR, XRR, XPS, MOKE, ESR, FMR, transport electrical and magnetic measurements, Hall-effect), and many others.

• Brief description of your project / the project you would like to join:

  We are especially interested to contribute in the project on the topic of MW-optic quantum transduction or quantum memories. Two primary issues in quantum information processing are the transmission of quantum states from superconducting qubits over long distances and their storage for extended periods in quantum memories. One of the prospective approaches of coherent transfer of quantum information from the MW domain to the optical one (and vice versa) is to use a magnetic material as a mediator for coupling quantum states of MW photons to optical ones. In such systems, information is coherently transferred from the MW modes to spin oscillations (magnons), which in turn modulate optical radiation through magneto-optical interaction. A similar approach can be used in quantum memories. Especially the planar hybrid structures, which are better suited for on-chip integration, would be the most interesting object for the studies. One of the possible lines to study is to dope or interface the magnon material with optically active rare-earth ions. We can also propose to develop metasurface-based designs to enhance the photon–magnon interactions.
