  • Gaussian boson sampling reproduces distributions that are hard to calculate classically and were claimed to show quantum advantage in the noiseless limit. But now a classical algorithm is shown to reproduce experimental results when noise is large.

  • 140 years ago, John Henry Poynting demonstrated “by what paths and according to what law” electromagnetic energy travels. Theory and experiment now also reveal how waves acquire information as they scatter through their environment.

  • Acoustic and optical traps enable contactless manipulation of objects, but trapping has been limited to homogeneous environments. Wavefront shaping now extends this versatile manipulation tool to dynamic and disordered media.

  • Although manipulation of objects using light and sound waves is an established technique, it has so far been confined to static environments. Iterative tailoring of acoustic far fields now allows control of objects in disordered and dynamic media.

  • Mechanical modes promise applications in continuous-variable quantum information processing, but only if the final two elements—squeezing and nonlinearity—are achieved. Experiments with an oscillator coupled to a transmon qubit now achieve this.

  • In many schedule-based systems, timeliness is paramount. A recent study provides insights into delay accumulation in networks, revealing a phase transition with connections to the physics of interfaces.

  • The rotation of holes jumping between quantum dots in silicon quantum computers creates additional complexity for two-qubit operations. Understanding the rules of this somersaulting movement is key to the progress of hole-based qubit technology.

  • Timeliness is a crucial property for the optimal functioning of socio-technical systems where delays can propagate. Now it is shown that a stylized model of delay propagation on temporal networks shows a phase transition that can trigger avalanches.

  • Spatial heterogeneity in disease transmission rates and in mixing patterns between regions makes predicting epidemic trajectories hard. Quantifying the mixing rates within and between spatial regions can improve predictions.
