Gregor Weihs is a quantum physicist whose research interests include fundamental physics both experimental and theoretical, quantum and semiconductor optics and quantum information.

He currently focuses on novel sources of entangled photon pairs from nonlinear waveguides, via strong coupling in semiconductor microcavities, and from semiconductor quantum dots. He also studies quantum communication and the foundations of physics.
