    The longest coherence time of a single qubit of more than ten minutes is observed in a 171Yb+ ion. After sympathetically cooling the 171Yb+ ion qubit with a 138Ba+ ion, noise from magnetic-field fluctuations and the local oscillator is suppressed by a dynamic decoupling scheme.

    More than half a century after describing interference of discrete states with a continuum, Ugo Fano's work is as relevant as ever. And Fermi beat him to it.

    Room-temperature single-photon emission at several wavelengths in the near-infrared, including the telecom window, is realized by organic colour centres chemically implanted on chirality-defined single-walled carbon nanotubes.

    Isolated attosecond pulses (IAPs) in the extreme-ultraviolet range are generated by the interaction of half-cycle mid-infrared pulses with gas (Xe, Kr or Ar) and solid media (quartz). The energy of the IAPs is optically tunable over an octave.

    Variable micropotentials for light are created by thermo-optic imprinting of a dye–polymer solution within a microcavity. A thermalized photon Bose–Einstein condensate as well as the coupling and eigenstate hybridization of sites are demonstrated.

    Counter-propagating solitons are generated in microresonator systems, producing dual-soliton frequency-comb streams with different repetition rates but high relative coherence useful for spectroscopy and laser ranging systems.

    A unidirectional photonic wire laser has been developed by integrating reflectors into terahertz quantum cascade lasers. The transverse dimension is much smaller than the lasing wavelength (80 μm). A record wall-plug power efficiency of 1% is achieved.
