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.
If a polarization excess is injected in many-spin quantum system which is initially in a high-temperature equilibrium, then this “excitation†would spread all over as consequence of spin-spin interactions.

Quantum correlations are strongly enhanced near quantum critical points, which opens attractive prospects for applications such as quantum-enhanced metrology.

“We propose to use Quantum Hall edge channels in order to generate long-range entanglement between spatially separated spin qubits. Since the entanglement is actively stabilized by purely dissipative dynamics, our scheme is inherently robust against noise and imperfections.”

A 3-mode optomechanical system (e.g., with two electromagnetic fields coupled to a single mode of a mechanical resonator) is a key element of hybrid quantum systems.

Several types of quantum-dot spin valves were recently realized. For such systems, we have analyzed the efficient transfer of angular momentum into the nuclear bath and the detection of nuclear-spin coherence through transport signatures.
