Kolloquien

Die Gastvorträge im Rahmen des MPQ-Kolloquiums finden von April bis Juli sowie von Oktober bis Januar jeweils dienstags um 14:30 Uhr statt. Verantaltungsort ist der Herbert-Walther-Hörsaal im Foyer des Max-Planck-Instituts für Quantenoptik.

Ansprechpartner für die wissenschaftliche Organisation:

Dr. Stephan Dürr und Dr. Thomas Udem

Wenn Sie einen Vortrag im Livestream verfolgen möchten, ist es nötig, dass Sie sich in eine entsprechende Mailing Liste eintragen. Daraufhin erhalten Sie Instruktionen zum Empfang des Livestreams.

Towards Highly Storage Efficiency of Optical Quantum Memory Based on Electromagnetically Induced Transparency Protocol

Towards Highly Storage Efficiency of Optical Quantum Memory Based on Electromagnetically Induced Transparency Protocol
Long-distance quantum communication based on quantum repeater protocol [mehr]
Schrödinger's famous cat Gedankenexperiment investigates how the laws of quantum mechanics extend into the macroscopic realm. An experimentally accessible model system in quantum optics is the superposition of two well-distinguishable coherent states - a so-called "cat state" - with a tunable degree of macroscopicity. Applying a high-finesse cavity we demonstrate a new method to create flying optical cat states. They are entangled to a single trapped atom, much like Schrödinger's original cat. I show control over various degrees of freedom of the cat states, which is a great asset for their potential application to continuous-variable quantum computing. [mehr]

Brillouin-based light storage in a photonic circuit (Dr. B. Stiller)

Brillouin scattering is a fundamental nonlinear opto-acoustic interaction present in optical fibres and other waveguides with important implications in fields ranging from modern telecommunication networks, signal processing and smart optical sensors. [mehr]
