Group: QCMC 2012
In the week 30th of July-3rd of August 2012, we are organizing the international conference QCMC 2012 (Quantum Communication, Measurement and Computing) in Vienna.
About 300 researchers from quantum physics gather to discuss the latest results from the research of quantum information, quantum communication, and quantum metrology.
Details of the conference you can find on: www.qcmc2012.org

QuIC: Cavity QED Experiment
First paper from the QUIC-QED experiment published:
Cavity QED with magnetically coupled collective spin states
We report strong coupling between an ensemble of nitrogen-vacancy center electron spins in diamond and a superconducting microwave coplanar waveguide resonator. The characteristic scaling of the collective coupling strength with the square root of the number of emitters is observed directly.
