We demonstrate the reversible mapping of a coherent state of light with a mean photon number (-)n approximately equal to 1.1 to and from the hyperfine states of an atom trapped within the mode of a high-finesse optical cavity. The coherence of the basic processes is verified by mapping the atomic state back onto a field state in a way that depends on the phase of the original coherent state. Our experiment represents an important step toward the realization of cavity QED-based quantum networks… Expand

A solid-state light–matter interface at the single-photon level
The coherent and reversible mapping of a light field with less than one photon per pulse onto an ensemble of ∼107 atoms naturally trapped in a solid is demonstrated by coherently absorbing the light field in a suitably prepared solid-state atomic medium. Expand

Synthesis of arbitrary quantum states via adiabatic transfer of Zeeman coherence.
A scheme for the preparation of general coherent superpositions of photon-number states is proposed by strongly coupling an atom to a cavity field, which can be transferred by (coherent) adiabatic passage to the cavity mode and a general field state can be generated without atomic projection noise.
