Commentary Top Building a successful university start-up   pp618 - 620 Richard Murray doi:10.1038/nphoton.2016.187 Thinking of creating your own company? Perseverance, pragmatism, flexibility and truly understanding your customers' needs are all vital ingredients for success. Research Highlights Top 2D materials: Solar purification | Light manipulation: Winding light beams | Fibre lasers: Triwavelength source | Holography: Optical forces for data storage | Semiconductor sources: High-power disk laser News and Views Top Optical storage: Antiferromagnets see the rainbow   pp622 - 623 Richard F. L. Evans doi:10.1038/nphoton.2016.192 Antiferromagnets are considered mysterious due to their lack of macroscopic magnetization. Researchers have now found a way to manipulate their magnetic ordering using different wavelengths of light. See also: Letter by Manz et al. Quantum communications: Teleportation becomes streetwise   pp623 - 625 Frédéric Grosshans doi:10.1038/nphoton.2016.190 Quantum teleportation is at the heart of many quantum information protocols. Two teams have now performed it over several kilometres of metropolitan fibre networks, paving the way for future quantum technologies on the city scale.

A new spectroscopic study reveals the full interaction dynamics, with promising ramifications for future lightwave-driven petahertz electronics. View from... PECS-XII: Strength in diversity   pp628 - 629 Oliver Graydon doi:10.1038/nphoton.2016.191 Progress in the development of highly sensitive biosensors and tailored thermal emission were two highlights of the 2016 PECS conference on photonic crystals in York, UK.

The photophysical properties of single-photon emitters and efforts towards scalable system integration are also discussed. Letters Top Experimental investigation of the no-signalling principle in parity–time symmetric theory using an open quantum system   pp642 - 646 Jian-Shun Tang, Yi-Tao Wang, Shang Yu, De-Yong He, Jin-Shi Xu et al. doi:10.1038/nphoton.2016.144 The violation of the no-signalling principle — information can be transmitted faster than light — is experimentally investigated using entangled photons. It can be simulated when the parity–time symmetrically evolved subspace is solely considered. Designing whispering gallery modes via transformation optics   pp647 - 652 Yushin Kim, Soo-Young Lee, Jung-Wan Ryu, Inbo Kim, Jae-Hyung Han et al. doi:10.1038/nphoton.2016.184 Transformation optics makes it possible to design whispering-gallery-mode resonators with high Q factors and unidirectional emission. Reversible optical switching of antiferromagnetism in TbMnO3    pp653 - 656 Sebastian Manz, Masakazu Matsubara, Thomas Lottermoser, Jonathan Büchi, Ayato Iyama et al. doi:10.1038/nphoton.2016.146 Laser-controlled writing and erasure of antiferromagnetic domains in multiferroic TbMnO3 using light pulses of two different colours is demonstrated. See also: News and Views by Evans Experimental realization of optomechanically induced non-reciprocity   pp657 - 661 Zhen Shen, Yan-Lei Zhang, Yuan Chen, Chang-Ling Zou, Yun-Feng Xiao et al. doi:10.1038/nphoton.2016.161 Non-magnetic non-reciprocal transparency and amplification is experimentally achieved by optomechanics using a whispering-gallery microresonator. The idea may lead to integrated all-optical isolators or non-reciprocal phase shifters. Geopotential measurements with synchronously linked optical lattice clocks   pp662 - 666 Tetsushi Takano, Masao Takamoto, Ichiro Ushijima, Noriaki Ohmae, Tomoya Akatsuka et al. doi:10.1038/nphoton.2016.159 Real-time geopotential measurements with two synchronously linked optical lattice clocks are demonstrated. A height difference between the two clocks separated by 15 km is determined, with an uncertainty of 5 cm, by means of a gravitational redshift. Sub-cycle optical phase control of nanotunnelling in the single-electron regime   pp667 - 670 Tobias Rybka, Markus Ludwig, Michael F. Schmalz, Vanessa Knittel, Daniele Brida et al. doi:10.1038/nphoton.2016.174 Carrier-envelope-phase control of the electronic current over a laterally confined tunnelling gap a few nanometres wide yields current densities above 50 MA cm–2 driven by picojoule-level optical pulses at room temperature. Quantum teleportation with independent sources and prior entanglement distribution over a network   pp671 - 675 Qi-Chao Sun, Ya-Li Mao, Si-Jing Chen, Wei Zhang, Yang-Fan Jiang et al. doi:10.1038/nphoton.2016.179 The first field test of quantum teleportation is implemented over a 30 km optical fibre network with independent quantum light sources. To establish a robust quantum teleportation system in the real world, several feedback mechanisms are developed.
