We report that quantum discord can be protected from decoherence by making use of weak and reversing quantum measurements, making it possible to distribute quantum correlation between two remote parties in noisy environment.
We report an experimental realization of an atomic vapor quantum memory for the photonic polarization qubit. The quantum memory is realized by means of electromagnetically-induced transparency in two spatially separated ensembles of warm Rubidium atoms in a single vapor cell. We have fully characterized the memory with quantum process tomography.
We experimentally demonstrated that the decoherence due to amplitude damping can be suppressed using quantum measurement reversal. By implementing two partial measurements, we succeeded in preferentially selecting the cases where states do not experience decoherence.
We propose and demonstrate a postselection-free linear optical minimum disturbance measurement (MDM) device which optimally measures the polarization qubit of a single-photon with the help of an ancillary path qubit introduced to the same photon.
