We prepare Schrodinger cats and other non-classical photonic states in a high-Q cavity. We reconstruct them using maximum entropy principle from an incomplete set of quantum non-demolition measurements performed with Rydberg atoms crossing the cavity.

Conditional Large Fock State Preparation and Field State Reconstruction in Cavity QED

Marcelo França Santos, E. Solano, R. L. de Matos Filho

We propose a scheme for producing large Fock states in cavity QED via the implementation of a highly selective atom-field interaction. It is based on Raman excitation of a three-level atom by a classical field and a quantized field mode. Selectivity appears when one tunes to resonance a specific transition inside a chosen atom-field subspace, while other transitions remain dispersive, as a consequence of the field dependent electronic energy shifts. We show that this scheme can be also employed for reconstructing, in a new and efficient way, the Wigner function of the cavity field state.

Optimal time-resolved photon number distribution reconstruction of a cavity field by maximum likelihood

C. Sayrin, I. Dotsenko, S. Gleyzes +3 more

We present a method for reconstructing the average evolution of the photon number distribution of a field decaying in a high- Q cavity. It applies an iterative maximum likelihood state reconstruction algorithm to the diagonal elements of the field density operator. It is based on quantum non-demolition measurements carried out with atoms crossing the cavity one by one. A small set of successively detected atoms defines a positive operator valued measure (POVM). The reconstruction is performed by applying this POVM to a large ensemble of field realizations. An optimal POVM based on the detection of a minimal number of atoms is shown to be sufficient to ensure an unambiguous convergence of the reconstruction. The cavity crossing time of this minimal number of atoms must be much shorter than the lifetime of the largest photon number present in the field. We apply the method to monitor the evolution of number states prepared by quantum feedback in a recent experiment. The method could also be useful in circuit QED experiments.
