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.

QuIC: Ultra cold atoms into a cryogenic enviroment

cryo transport coils

Since end of 2010, the 4 Kelvin part of the QuiC experiment, suceeded in transporting via a magnetic conveyor belt, an ensemble ultra cold atoms into a cryostat. Several 107 atoms of 87Rb are stored in the final quadrupole magnetic trap. The transport coils are partially normal conducting and partially super conducting.
