27 A universal set of logic gates in a superconducting quantum circuit is shown to have gate fidelities at the threshold for fault-tolerant quantum computing by the surface code approach, in which the quantum bits are distributed in an array of planar topology and have only nearest-neighbour couplings.

26 Quantum gates — in which stationary quantum bits are combined with ‘flying’ quantum bits, that is, photons — will be essential in quantum networks; such a gate, between a laser-trapped atomic quantum bit and a single photon, is now reported.

25 Strongly coupling a photon to a single atom trapped in the near field of a nanoscale photonic crystal cavity results in a light switch which can be turned on and off with a single photon.

22 Fast optical pulses create a plasma of electrons and holes in a semiconductor in which excitons (pairs of holes and electrons) and combinations of two excitons emerge; now a stable liquid-like droplet of electrons and holes has been detected and called a ‘dropleton’.

17 Schrodinger’s cat paradox embodies the open question of whether quantum effects can survive at macroscopic scales. A quantum optics experiment explores this question by creating entanglement between a microscopic and a macroscopic system.

16 A magnetic field can lift the spin degeneracy of electrons. This Zeeman effect is an important route to generating the spin polarization required for spintronics. It is now shown that such polarization can also be achieved without the need for magnetism. The unique crystal symmetry of tungsten selenide creates a Zeeman-like effect when a monolayer of the material is exposed to an external electric field.
