Adrian Cho gives an accurate and realistic account of quantum radar in Science Magazine today.

Our new paper shows chip-scale transduction of microwave and optical photons via radiation pressure at mK temperature. It achieves the lowest V_π to date and we carefully analyze and model the conversion noise that currently hinders using it for quantum applications in continuous wave mode.
Big thanks to the team around Georg, Matthias and Shabir as well as our funders: (ERC, HOΤ and IST)!

Together with Nicholas Lambert and Harald Schwefel we are organizing a WE-Heraeus-Seminar next spring with a great selection of confirmed speakers (to be completed).

When: 30 May – 03 Jun 2021
Where: Physikzentrum Bad Honnef

Our proof of principle demonstration of quantum radar is out now. It shows that an entangled source of microwave radiation can result in a relative object detection advantage compared to a classically correlated noise source.

Alfredo made it to the cover of our new institute annual report in his last week at IST before moving on to Scantinel Photonics. We are sad and wish him good luck!

We are excited to start working on superconducting quantum local area networks (SuperQuLAN) together with TU Wien, ETH Zurich, MPQ, CSIC and Zurich Instruments.

Check out the article at IST news.

Alfredo won the “IST Outstanding Scientific Achievement award 2019” for his experimental work on electro-optic frequency combs and his theoretical (and experimental) work on  microwave optical state transfer last year.

Congratulations!

Many thanks to Andrea Trioni for designing our first group logo!

Our new paper shows how a mechanical oscillator can deterministically generate stationary entangled microwave radiation.
