Experimental Purification of Single Qubits
arXiv:quant-ph/0403118 · doi:10.1103/PhysRevLett.93.170501
Abstract
We report the experimental realization of the purification protocol for single qubits sent through a depolarization channel. The qubits are associated with polarization encoded photon particles and the protocol is achieved by means of passive linear optical elements. The present approach may represent a convenient alternative to the distillation and error correction protocols of quantum information.
