Efficient quantum memory and entanglement between light and an atomic ensemble using magnetic fields

  title={Efficient quantum memory and entanglement between light and an atomic ensemble using magnetic fields},
  author={Christine A. Muschik and Klemens Hammerer and Eugene Simon Polzik and J. Ignacio Cirac},
We present two protocols, one for the storage of light in an atomic ensemble and the subsequent retrieval, and another one for the generation of entanglement between light and atoms. They rely on two passes of a single pulse through the ensemble, Larmor precessing in an external field. Both protocols work deterministically and the relevant figures of merit such as the fidelity or the EPR variance scale exponentially in the coupling strength. We solve the corresponding Maxwell-Bloch equations… CONTINUE READING
