Continuous variable entanglement distillation by cascaded photon replacement Yasamin Mardani Yasamin Mardani1374@gmail com September 22 2020 Department of Physics Isfahan University of Technology Isfahan 84156 83111 Iran University Code IUT 77142 Degree M S c Language Farsi supervisor Dr Mehdi Abdi Abstract We study the entanglement distillation in continuous variable systems when a photon replacement protocol is employed A cascaded protocol is studied and we find that the resultant entanglement increases by increasing the number of repetitions Interestingly the entanglement enhancement is not sensitive to the asymmetry of the protocol and gives the same result for any arrangement in the absence of loss The non Gaussianity of the outcome state is also studied and it is found that the non Gaussianity of the state dramatically depends on the experimental arrangements By providing practical information on photon replacement operation this work is one step towards realization of universal quantum computation In particular in setups where deGaussifying protocols are only applicable to one of the parties Keywords entanglement distillation entanglement enhancement photon replacement de Gaussifying protocol
