The editors of PRX and David DiVincenzo share with readers their views of the just published paper by Jones et al. on quantum-computer architecture.

Using deftly designed and fabricated devices combining nitrogen-vacancy centers with on-chip heating and thermometry components, a group at University of California, Santa Barbara, expand the measurement, understanding, and control of single spins in the NV centers into a broad thermal range spanning from room temperature to above 600 K.

Combining a laser pulse with liquid in microcapillary tubes in a series of experiments, a fluid-mechanics group at University of Twente finds a new way of generating highly focused and ultrafast liquid jets and understands how to control the jet speed.

An Australian group at Griffith University demonstrates for the first time Einstein’s quantum-mechanical “spooky action” over a long distance of 1 km.

The quantum Hall and quantum spin Hall states are shown to coexist in a graphene-based electronic transport device.

A key parameter that governs the crucial early phase of epidemics can be reliably estimated with methods from network theory and stochastic processes.

Two researchers at California Institute of Technology present the first graphene-based hot-electron bolometer capable of sensitive detection of microwave signals.

Physicists and computer scientists join force in this audacious paper to draw up a paradigmatic blueprint for the architecture of large-scale quantum computers.

Using topological invariants to classify and understand topological insulators is as natural and as fundamental as using genus to distinguish spheres from tea pots. Identifying and computing topological invariants for insulators with electron-electron interactions is, however, difficult. With analytical insight and skill, two physicists have succeeded in that task.

A group of German physicists discover a new paradigm of Devil’s-staircase-like percolation transitions in complex networks, expanding qualitatively the current understanding of a hotly debated topic.

A plasmonics group at University of Stuttgart discover optimal designs for nanoscale metallic structures that can enable sensitive detection or discrimination of chiral molecules.

Förster resonant energy transfer between two Rydberg atoms, tuned by a small electric field, offers a new way of not only inducing coherent dynamics of the atom pair, but controlling it, too.

Stochastic resonance, the counterintuitive phenomena of amplification of a weak signal by random noise, is revealed for the first time in single short DNA hairpins.

Restricting the motion of electrons from the continuous in an electron gas to discrete hopping on a lattice leads to the emergence of new topologically ordered states that are related to fractional quantum Hall states.

Why, and how do we make new friends or establish fresh social ties? A new statistical approach leads to a number of illuminating insights, by taking advantage of rich online-social-networking data with single-action time resolution.

Getting electromagnetic waves through an aperture whose size is significantly smaller than the wavelength is very difficult. Roberto Merlin from University of Michigan shows how this difficulty can be overcome by coupling such a subwavelength aperture to an electromagnetic resonant device.

In theory, careful selection of observables within a quantum system can allow a subsystem to be designed that is entirely free of any quantum constraints including the uncertainty principle.

Inertial effect of a flowing fluid, often a complicating factor in hydrodynamics, offers a way to high-purity, high-throughput shape-based separation of manmade particles or biological cells in microfluidic channels.

Analysis of dictionaries with methods from statistical physics and graph theory shows how definitional loops in human lexicons are essential for the addition of new concepts and the growth of language.

Having a table-top x-ray free-electron-laser source at their disposal must be the dream of every x-ray scientist. A new design based on the currently available laboratory-scale laser-plasma particle accelerators shows that this dream should be within reach before too long.
