Chemical composition mapping with nanometre resolution by soft X-ray microscopy pp765 - 769 David A. Shapiro, Young-Sang Yu, Tolek Tyliszczak, Jordi Cabana, Rich Celestre et al. doi:10.1038/nphoton.2014.207 A soft X-ray ptychography approach can now image 5-nm-sized objects. Chemical component distributions in the delithiation of LiFePO4 nanoplates — a process relevant for energy storage — links structural defects to chemical phase propagation. |

Quantum teleportation on a photonic chip pp770 - 774 Benjamin J. Metcalf, Justin B. Spring, Peter C. Humphreys, Nicholas Thomas-Peter, Marco Barbieri et al. doi:10.1038/nphoton.2014.217 Teleportation of a photonic qubit is demonstrated on a reconfigurable photonic chip. All of the key elements of the teleportation protocol are performed. The average fidelity for the three linearly independent quantum states is higher than the classical limit, which certifies the capability of teleporting a general quantum state.

Quantum teleportation from a telecom-wavelength photon to a solid-state quantum memory pp775 - 778 Félix Bussières, Christoph Clausen, Alexey Tiranov, Boris Korzh, Varun B. Verma et al. doi:10.1038/nphoton.2014.215 Quantum teleportation of the state of a qubit encoded in the polarization state is demonstrated from a telecom-wavelength photon to a solid-state quantum memory via 24.8 km of optical fibre. It is the longest distance ever reached in a teleportation experiment involving a quantum memory. |

High photon flux table-top coherent extreme-ultraviolet source pp779 - 783 Steffen Hädrich, Arno Klenke, Jan Rothhardt, Manuel Krebs, Armin Hoffmann et al. doi:10.1038/nphoton.2014.214 High photon flux with up to 1012 photons in the 25–40 eV range has been achieved in a new table-top coherent extreme ultraviolet (EUV) source based on phase-matched high-harmonic generation using a fibre laser. Intense and compact EUV sources are needed for certain types of spectroscopic and imaging applications. |

Non-invasive single-shot imaging through scattering layers and around corners via speckle correlations pp784 - 790 Ori Katz, Pierre Heidmann, Mathias Fink and Sylvain Gigan doi:10.1038/nphoton.2014.189 Diffraction-limited imaging in a variety of complex media is realized based on analysis of speckle correlations in light captured using a camera phone.

On-chip generation of high-order single-photon W-states pp791 - 795 Markus Gräfe, René Heilmann, Armando Perez-Leija, Robert Keil, Felix Dreisow et al. doi:10.1038/nphoton.2014.204 Single-photon W-states — coherent superpositions of all qubits with equal probability amplitudes — involving up to 16 spatial modes are generated by means of evanescently-coupled waveguide technology. A scheme capable of exploiting the maximal entanglement of W-states is proposed for the efficient generation of random numbers. |

Ultimate classical communication rates of quantum optical channels pp796 - 800 V. Giovannetti, R. García-Patrón, N. J. Cerf and A. S. Holevo doi:10.1038/nphoton.2014.216 The Gaussian minimum entropy conjecture—a long-standing open question—has now been proved for single-mode phase-insensitive bosonic Gaussian channels. This establishes the ultimate achievable bit rate under an energy constraint and provides long-awaited proof that the single-letter classical capacity of these channels is additive. |

Direct generation of three-photon polarization entanglement pp801 - 807 Deny R. Hamel, Lynden K. Shalm, Hannes Hübel, Aaron J. Miller, Francesco Marsili et al. doi:10.1038/nphoton.2014.218 A three-photon entangled Greenberger–Horne–Zeilinger state is directly produced by cascading two entangled down-conversion processes. Experimentally, 11.1 triplets per minute are detected on average. The three-photon entangled state is used for state tomography and as a test of local realism by violating the Mermin and Svetlichny inequalities. |

Nature Communications soon to be fully open access From 20th October Nature Communications, will become fully open access for all new submissions. If an author has a manuscript they wish to submit to the journal via the subscription route, they must submit before 20th October. After this date all new submissions, if accepted, will be published open access and an article processing charge (APC) will apply. For any questions on the switch, open access or advice on policies and funding, visit our website, read the press release or contact our dedicated support team at openaccess@nature.com. | | | |
