On an irregular basis various Special Seminars take place at the MPQ. The seminars are organized by scientists of our divisions, administration or staff representatives. The location will be announced with the event.
Host: MPQ, Quantum Dynamics Division
In this talk I will speak about our source of light-matter quantum states based on laser-cooled atoms. In particular, I will explain the capabilities developed in order to transfer photonic qubits from this system to another matter platform that consists on a crystal doped with rare-earth ions. Photonic qubits generated by the atomic cloud were frequency converted and temporally shaped in order to have an optimum interaction with the ions in the crystal. These capabilities enabled to perform quantum state transfer between these two very different matter systems: the laser-cooled gas and the crystal. [more]

Quantum storage of multi-mode entanglement based on cold atomic ensembles (Dr. W. Zhang)

Multi-mode entanglement enables quantum communication with higher channel capacity and more efficient quantum-information processing and also is compatible with diverse quantum networks. [more]

One, Two, Many Modes: Developent & Application of High-dimensional Systems for Quantum Information Science (Dr. R. Kruse)

In recent years, one of the main quests in quantum optics has been to finally show that quantum-enhanced applications surpass their classical counterparts. [more]

Improved sensitivity to the electron´s electric dipole moment using YbF molecules (Dr. I. Rabey)

It is well known that the electron has a magnetic dipole moment. [more]

Quantum optomechanics with superfluid helium density waves (Alexey Shkarin)

The field of optomechanics deals with the interaction between light and mechanical objects. [more]
