Resistance noise in memristive devices is often described as a thermally activated process across simple energy barriers, but this can underestimate the role of entropy in a complex free energy landscape.

Encoding quantum information in qudits instead of qubits allows for several advantages, but scalable native entangling techniques would be needed. Here, the authors show how to use light-shift gates to perform entangling operations on trapped ion systems, with a calibration overhead which is independent on the qudit dimension.

How landscapes are arranged affects soil pathogenic fungi worldwide. The authors reveal the global pattern and pronounced scale-dependency of landscape complexity and land-cover quantity on soil pathogenic fungal diversity.

Wheat yields in northwest Europe have plateaued since the mid-1990s. This study finds that no ceiling in genetic yield potential has been reached and that climatic conditions have not constrained wheat yields across high-yielding environments in the region thus far; suboptimal agronomic management is responsible for unrealized wheat yield progress of 67–114 kg ha⁻¹ yr⁻¹ during the period 1994–2016.
