Gerhard Rempe (born 22 April 1956) is a German physicist, Director at the Max Planck Institute of Quantum Optics and Honorary Professor at the Technical University of Munich.

The thesis was entitled "investigation of the interaction of Rydberg atoms with radiation" and reports on experiments performed in the group of Herbert Walther.

He declined simultaneous offers to the Swiss Federal Institute of Technology in Zurich, Switzerland, and the University of Bayreuth, Germany.

[5] A remarkable feature of the interface is its ability to detect single photons nondestructively,<[6] which opens new perspectives for a scalable quantum computer.

By means of an atom interferometer he was able to demonstrate experimentally that for an observed object passing through a double-slit arrangement quantum mechanical wave-particle duality is based on entanglement, instead of Heisenberg’s uncertainty relation for position and momentum, as often stated in textbooks.
