Dynamical decoupling in optical fibers: Preserving polarization qubits from birefringent dephasing
One of the major challenges in quantum computation has been to preserve the coherence of a quantum system against dephasing effects of the environment. The information stored in photon polarization, for example, is quickly lost due to such dephasing, and it is crucial to preserve the input states when one …
