A scheme for generation of multi-photon GHZ states with cross-Kerr nonlinearities
نویسندگان
چکیده
With the help of cross-Kerr nonlinearities and homodyne measurement, we propose a scheme to generate three-photon GHZ states. Under the same framework, multi-photon GHZ state can be also realized. Compared with the previous ones, our scheme is much more simplified and lower errors. Moreover, only some linear elements and weak cross-Kerr mediums are employed, which make our scheme more feasible in the experiment. PACS: 03.67.-a

Generation of four-photon polarization entangled decoherence-free states with cross-Kerr nonlinearity
We propose a theoretical protocol for preparing four-photon polarization entangled decoherence-free states, which are immune to the collective noise. With the assistance of the cross-Kerr nonlinearities, a two-photon spatial entanglement gate, two controlled-NOT gates, a four-photon polarization entanglement gate are inserted into the circuit, where X homodyne measurements are aptly applied. Co...
متن کاملConversion of entangled states with nitrogen-vacancy centers coupled to microtoroidal resonators.
We propose efficient schemes for converting three-photon, four-photon and five-photon GHZ state to a W state or Dicke state, respectively with the nitrogen-vacancy (N-V) centers via single-photon input-output process and cross-Kerr nonlinearities. The total success probability can be improved by iterating the conversion process for the case of three-photon and five-photon while it does not requ...

متن کاملA Bootstrapping Approach for Generating Maximally Path-Entangled Photon States
We propose a bootstrapping approach to generation of maximally path-entangled states of photons, so called “NOON states”, achievable within the current experimental technology. Strong atom-light interaction of cavity QED can be employed to generate NOON states with about 100 photons; which can then be used to boost the existing experimental Kerr nonlinearities based on quantum coherence effects...
