Abstract: Bohr proposed that the outcome of a measurement becomes objective and real, and, hence, classical, when its results can be communicated by classical means. In this work we revisit Bohr’s p...
Abstract: To create and manipulate non-classical states of light for quantum information protocols, a strong, nonlinear interaction at the singlephoton level is required. One approach to the generati...
Abstract: An elementary quantum network operation involves storing a qubit state in an atomic quantum memory node, and then retrieving and transporting the information through a single photon excitat...
Abstract: The great potential of quantum computing requires two essential ingredients for its realiza-tion: high- delity quantum logic operations and a physical implementation which can be scaled up ...
Abstract: Quantum correlations are at the heart of quantum information science1–3. Their detection usually requires access to all the correlated subsystems4,5. However, in many realistic scenarios t...
Abstract: As a direct consequence of the no-cloning theorem [1], the deterministic amplification as in classical communication is impossible for quantum states. This calls for more advanced technique...
