Quantum optics: Receiver beats quantum limit   pp87 - 89 Kenji Tsujino doi:10.1038/nphoton.2013.4 The report of a quantum receiver that can distinguish quadrature-phase-shifted keyed signals with an error rate beyond the standard quantum limit bodes well for improving the performance of coherent optical communication systems.

This Review article discusses multiphoton microscopy capable of such analysis, along with technologies that are pushing the limits of phenomena that can be quantitatively imaged. Dispersive Fourier transformation for fast continuous single-shot measurements   pp102 - 112 K. Goda and B. Jalali doi:10.1038/nphoton.2012.359 It's challenging to measure non-repetitive events in real time in the field of instrumentation and measurement. Dispersive Fourier transformation is an emerging method that permits capture of rare events, such as optical rogue waves and rare cancer cells in blood. This Review article covers the principle of dispersive Fourier transformation and its implementation in diverse applications. Letters Top Marker-free phase nanoscopy   pp113 - 117 Yann Cotte, Fatih Toy, Pascal Jourdain, Nicolas Pavillon, Daniel Boss, Pierre Magistretti, Pierre Marquet and Christian Depeursinge doi:10.1038/nphoton.2012.329 By recording digital holograms created from different illumination directions and subsequently processing them in a complex deconvolution scheme, scientists are able to capture details of living biological samples with subwavelength resolution. See also: News and Views by Brooker Radiofrequency signal-generation system with over seven octaves of continuous tuning   pp118 - 122 Garrett J. Schneider, Janusz A. Murakowski, Christopher A. Schuetz, Shouyuan Shi and Dennis W. Prather doi:10.1038/nphoton.2012.339 Researchers use sideband injection-locked lasers to generate low-noise, high-frequency radio signals that can be tuned over the range of 0.5-110 GHz. This technique is amenable to compact integration and, in principle, operation at even higher frequencies. Experimental demonstration of optical transport, sorting and self-arrangement using a 'tractor beam'   pp123 - 127 O. Brzobohatý, V. Karásek, M. Šiler, L. Chvátal, T. Čižmár & P. Zemánek doi:10.1038/nphoton.2012.332 The concept of an optical pulling force, or /`tractor beam/', has received increasing interest following recent theoretical proposals. Scientists have now experimentally verified this concept and demonstrated that the orientation of the beam's linear polarization strongly influences the behaviour of the object being pulled, in particular the direction of its delivery. Real-time observation of ultrafast Rabi oscillations between excitons and plasmons in metal nanostructures with J-aggregates   pp128 - 132 Parinda Vasa, Wei Wang, Robert Pomraenke, Melanie Lammers, Margherita Maiuri, Cristian Manzoni, Giulio Cerullo and Christoph Lienau doi:10.1038/nphoton.2012.340 Researchers observe Rabi oscillations in a metal structure with a J-aggregate nonlinear medium and coherent energy transfer between excitonic quantum emitters and surface plasmons. The coupling energy is controlled on the 10 fs timescale by varying the exciton density. This work demonstrates the potential of nonlinear ultrafast plasmonics. Realization of three-dimensional guiding of photons in photonic crystals   pp133 - 137 Kenji Ishizaki, Masaki Koumura, Katsuyoshi Suzuki, Kou Gondaira and Susumu Noda doi:10.1038/nphoton.2012.341 Researchers demonstrate the three-dimensional routing of light through a three-dimensional photonic crystal. Before transmission, the light is bent both vertically and horizontally, split and trapped.

The response time of less than 5 ns indicates that phase modulation bandwidths greater than 50 MHz are possible with a highly sensitive atomic-vapour-based scheme. Articles Top Limits on classical communication from quantum entropy power inequalities   pp142 - 146 Robert König and Graeme Smith doi:10.1038/nphoton.2012.342 Researchers provide tight bounds for the classical information capacity of a Bosonic thermal noise channel. They also compare these limits with the well-known lower bound of the channel and an upper bound first introduced by Holevo and Werner in their seminal work on the subject. Experimental demonstration of a receiver beating the standard quantum limit for multiple nonorthogonal state discrimination   pp147 - 152 F. E. Becerra, J. Fan, G. Baumgartner, J. Goldhar, J. T. Kosloski and A. Migdall doi:10.1038/nphoton.2012.316 Researchers present a quantum receiver based on a novel adaptive measurement scheme and a high-bandwidth, high-detection-efficiency system for single-photon counting. The receiver unconditionally discriminates between four nonorthogonal coherent states with error probabilities 6 dB below the standard quantum limit for a wide range of input powers. See also: News and Views by Tsujino Strain-induced pseudomagnetic field and photonic Landau levels in dielectric structures   pp153 - 158 Mikael C. Rechtsman, Julia M. Zeuner, Andreas Tunnermann, Stefan Nolte, Mordechai Segev and Alexander Szameit doi:10.1038/nphoton.2012.302 Magnetic effects are fundamentally weak at optical frequencies. Now, by applying inhomogeneous strain in photonic band structures of a honeycomb lattice of waveguides, scientists show experimentally and theoretically that it is possible to induce a pseudomagnetic field at optical frequencies. The field yields 'photonic Landau levels', which suggests the possibility of achieving greater field enhancements and slow-light effects in aperiodic photonic crystal structures than those available in periodic structures.

Nature Photonics spoke to Mordechai Segev, Mikael Rechtsman, Alexander Szameit and Julia Zeuner about their unique approach.
