Xiaoyong Huang
doi:10.1038/nphoton.2014.221
The development of high-performance red-emitting phosphors provides new opportunities for fabricating white LEDs with both high colour rendering index and high luminous efficacy.

Instabilities, breathers and rogue waves in optics   pp755 - 764
John M. Dudley, Frédéric Dias, Miro Erkintalo and Goëry Genty
doi:10.1038/nphoton.2014.220
Curious wave phenomena that occur in optical fibres due to the interplay of instability and nonlinear effects are reviewed.

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.
