About Jiang Group

In our group, we harness the advantage of cold atoms and superconducting circuits to study the light-matter interaction. By combining these two platforms, we aim to push the boundaries of quantum science and technology.

Cold atom: we cool down the atoms to a temperature very close to absolute zero, below 0.0001 K -- without using a refrigerator, but lasers! And we use a magnetic field to trap the atoms, forming a magneto-optical trap. From there, we study the nonlinear interactions between cold atoms and lasers, which generate single photons that possess quantum behavior.

Superconducting circuit: we study superconducting circuits that contain nonlinear elements and interact with microwave and millimeter wave signals. The superconducting circuit is placed in a dilution refrigerator and cooled down to 10 mK, where its quantum behavior becomes more pronounced. We use these circuits for quantum information processing and quantum sensing in a cryogenic environment.
