We are a research group at the new Institute of Science and Technology Austria. We started our lab in early 2016 and study quantum effects in electrical, mechanical and optical chip-based devices. Our main objective is to advance and integrate quantum technology for computation, communication and sensing.
Quantum Integrated Devices
One of the most promising solid-state systems for quantum computation and simulation is based on superconducting electrical circuits, which are addressed and controlled with microwave frequency photons (see e.g. Schoelkopf and Girvin). Photons at optical wavelengths on the other hand, are the best candidates for establishing quantum networks due to their weak interaction with the environment, large bandwidth, and resilience to thermal noise. Finding a way to efficiently interface these two domains is one of the most exciting areas of experimental physics today.
Mechanically compliant opto-electromechanical devices have recently emerged as a promising tool to unite these two regimes. Such mechanical circuit elements may not only find applications in quantum-coherent wavelength conversion and as quantum memories, they can also be used in classical transduction and sensing, and help understand heat flow in nano-structured matter. Our chip-based approach to realizing these hybrid devices is technologically challenging but promises high efficiency, bandwidth and scalability.
Our research is positioned at the intersection of quantum optics and mesoscopic condensed matter physics. In our lab we will focus on:
- developing novel types of superconducting circuits using advanced fabrication technologies,
- controlling and studying the dynamics of phonons in quantum electromechanical systems with acoustic bandgaps,
- working towards an integrated microwave photonic interface to coherently couple superconducting qubits to telecom wavelength fiber optics.
We are always looking for motivated and creative students who are eager to get involved in cutting edge research. Candidates interested in quantum physics and engineering, with a strong background in physics, electrical engineering, or materials science (Bachelor’s or Master’s degree) are encouraged to send me an email and apply to the graduate school of IST Austria.
Postdoc candidates interested in superconducting circuits, electro- and opto-mechanics are invited to contact me via email. A strong background in one or more of the following areas is desirable: theory of quantum optical systems, FEM simulations and software programming, high bandwidth microwave measurements and signal processing, optical measurement techniques and testing, micro- and nanofabrication, ultra-low temperatures.
