A quantum connection between light
and mechanics
Researchers at EPFL, Switzerland and the Max Planck Institute of Quantum Optics (MPQ, Garching near Munich) have demonstrated a microscopic system in which light can be converted into a mechanical oscillation and back.

 

Randolf Pohl receives Gustav Hertz Award
of the DPG
Dr. Randolf Pohl, scientist in the Laser Spectroscopy Division of Prof. Theodor W. Hänsch at the Max Planck Institute of Quantum Optics, is going to receive the Gustav Hertz Award of the German Physical Society (DPG).

 

Lauschangriffen auf der Spur
Photonen ermöglichen in der Quantenkryptographie die abhörsichere Übertragung von Nachrichten. Ein Forscherteam um Professor Harald Weinfurter konnte nun eine extrem einfache Art des Abhörens bei derartigen Systemen durchführen – aber auch gleich eine Gegenmaßnahme vorstellen.

 

Randolf Pohl receive ERC Starting Grants
Two scientists from the Max Planck Institute of Quantum Optics, have successfully applied for the “European Research Council Starting Grant”. Their proposals have been selected out of 4080 applications.

 

Fundamental matter-antimatter symmetry confirmed
International collaboration including MPQ scientists sets a new value for the antiproton mass relative to the electron with unprecedented precision.

 

Lightwave electronics at sharp metal tips
Scientists at the Max Planck Institute of Quantum Optics control for the first time the emission of electrons from metal tips with femtosecond lasers alone.

 

 

Microwave Guiding of Electrons
For the first time scientists at MPQ achieve guiding of electrons by purely electric fields.

 

 

 

 

Single atoms for detecting extremely weak forces
We report on injection locking of optically excited mechanical oscillations of a single, trapped ion.
MPQ-scientists demonstrate that due to synchronisation atoms can be influenced by forces as weak as 5 yoctonewton. ...

 

Cold atoms image microwave fields
Microwaves are an essential part of modern communication technology. Sophisticated techniques for measurement and characterization of microwave fields are an essential tool for the development of such circuits. ...

 

How small is the proton?
The proton – one of the universal building-blocks of all matter – is even smaller than had previously been assumed. This is the result obtained at the Paul-Scherrer-Institut (PSI) in Villigen (Switzerland) by an international research team. ...

 

Quantum Experiments in Microgravity
At the beginning of the 20th century two theories have been developed that have completely changed our understanding of the forces of nature: General Relativity and Quantum Mechanics. ...
