    "abstract": "A continuous-variable analog of the Deutsch\u0027s distillation protocol locally\noperating with two copies of the same Gaussian state is suggested.\nIrrespectively of the impossibility of Gaussian state distillation, we reveal\nthat this protocol is able to perform a squeezing concentration of the Gaussian\nstates with {\\em unknown} displacement. Since this operation cannot be\nimplemented using only single copy of the state, it is a new application of the\ndistillation protocol which utilizes two copies of the same Gaussian state.",
