Project A05: Resonator-enhanced design of quantum states

We will exploit the cavity-enhanced dispersive interaction of atoms and molecules with light for detection and control of quantum states of matter. In particular, we will devise theoretical concepts for (i) the off-resonant detection and quantum control of cold molecules in optical lattices, (ii) the detection of atom numbers and the generation of tailored atom-number squeezed states in atomic Bose-Einstein condensates for atom interferometers, (iii) the engineering and readout of quantum correlations in atomic clocks based on cold atoms in optical lattices, and (iv) the design of many-body quantum dynamics through continuous measurements and feedback.
