Conversion of a general quantum stabilizer code to an entanglement distillation protocol
نویسنده
چکیده
We show how to convert a quantum stabilizer code to a one-way or twoway entanglement distillation protocol. The proposed conversion method is a generalization of those of Shor-Preskill and Nielsen-Chuang. The distillable entanglement by the class of one-way protocols converted from stabilizer codes for a certain class of states is equal to or greater than the achievable rate of stabilizer codes over the channel corresponding to the distilled state, and they can distill asymptotically more entanglement from a very noisy Werner state than the hashing protocol. The recurrence protocol and the QPA protocol are equivalent to the protocols converted from [[2, 1]] stabilizer codes.

متن کاملImprovement of stabilizer based entanglement distillation protocols by encoding operators
We show a class of encoding operators for a quantum stabilizer code such that the number of gates of the inverse encoding quantum circuit is O(nk), where k qubits are encoded into n qubits by the stabilizer code. Then, we demonstrate that the performances of two-way EDPs are improved by the different choice of inverse encoding operators from the class of inverse encoding operators proposed in t...

We present a method for multipartite entanglement purification of any stabilizer state shared by several parties. In our protocol each party measures the stabilizer operators of a quantum errorcorrecting code on his or her qubits. The parties exchange their measurement results, detect or correct errors, and decode the desired purified state. We give sufficient conditions on the stabilizer codes...
متن کاملThe equivalence of two approaches to the design of entanglement distillation protocols
We show the equivalence of two approaches to the design of entanglement distillation protocols. The first approach is based on local unitary operations that yield permutations of tensor products of Bell states. The second approach is based on stabilizer codes.
