Nonlinear optics and quantum entanglement of ultraslow single photons
Two light pulses propagating with slow group velocities in a coherently prepared atomic gas exhibit dissipation-free nonlinear coupling of an unprecedented strength. This enables a single-photon pulse to coherently control or manipulate the quantum state of the other. Processes of this kind result in generation of entangled states of radiation field and open up new prospectives for quantum info...
متن کاملDynamic effects in nonlinear magneto-optics of atoms and molecules
A brief review is given of topics relating to dynamical processes arising in nonlinear interactions between light and resonant systems (atoms or molecules) in the presence of a magnetic field.
متن کاملInteraction of independent single photons based on integrated nonlinear optics.
The parametric interaction of light beams in nonlinear materials is usually thought to be too weak to be observed when the fields involved are at the single-photon level. However, such single-photon level nonlinearity is not only fundamentally fascinating but holds great potential for emerging technologies and applications involving heralding entanglement at a distance. Here we use a high-effic...
متن کاملManipulating atoms with photons*
Electromagnetic interactions play a central role in low energy physics. They are responsible for the cohesion of atoms and molecules and they are at the origin of the emission and absorption of light by such systems. This light is not only a source of information on the structure of atoms. It can also be used to act on atoms, to manipulate them, to control their various degrees of freedom. With...
متن کاملDetecting photons with Rydberg atoms
Unlike all other quantum technology platforms, photonics encodes quantum information without noise at room temperature, without the need for high vacuum, pumping / cooling, or magnetic / electrical shielding. Frustratingly, these advantages must be sacrificed when high-efficiency photon counting is required, as >95% photo-detection efficiency is only available via superconducting photo-detector...
