Welcome

I am a theoretical physicist with interest in quantum optics and superconducting devices. I am leading a small, young research group tackling challenging problems at the interface of quantum optics, quantum information, and condensed matter physics. The physical laws governing quantum systems are strange and counterintuitive. Yet, we can use them for secure communication or to solve problems that are too complex for standard, classical computers.

I focus particularly on superconducting quantum devices and their interactions with other quantum systems. Superconducting electrical circuits exhibit strong nonlinearities which are important for fully harnessing the power of quantum physics in information processing. At the same time, these nonlinear circuits are noisier than linear microwave resonators. I am trying to understand what limitations this noise presents for controlling long-lived microwave resonators and what consequences this has for quantum computing.

In addition, I am interested in frequency between microwave and optical quantum states. Microwaves are the key to controlling superconducting devices but cannot be sent through room-temperature channels because of thermal noise. Light is much more suitable for this task but it cannot talk to superconducting devices directly. That’s why we need conversion between the two if we want to connect superconducting quantum computers in a quantum internet.

Feel free to look around and, if you have any questions, get in touch!
