  Research Interests and achievement
Updated on Aug 3, 2015

We investigate quantum optics and quantum information using superconducting circuits.

The recent key results are as follows: 1. We demonstrate a single-photon router based on Autler-Townes splitting. A strong control tone can route a weak probe tone, see the details on PRL 107, 073601 (2011). 2. We generate antibunching and superbunching microwave state from a two level artificial atom, see details on PRL 108, 263601 (2012). 3. We enable photon-photon interaction via a three level atom, so called cross-Kerr effect, see details on PRL 111, 053601 (2013)
