Computers built of naturally probabilistic bits, as envisioned by Richard Feynman, share a large class of the applications anticipated for noisy intermediate-scale quantum (NISQ) computers. The authors show how the basic building block of a highly scaled memory technology, namely the familiar magnetic tunnel junction, can be straightforwardly modified by making use of two free layers that are each in the superparamagnetic regime, such that their natural fluctuations create highly efficient probabilistic bits at room temperature. The key insights obtained here may help to repurpose existing memory chips to build massively parallel probabilistic computers, with up to billions of p-bits.

In the liquid-metal ion sources that anchor key technologies for nanoscience, above a critical electric field strength a droplet of liquid metal sprouts a conical tip that undergoes continuous sharpening and field self-enhancement, culminating in ion emission. Despite decades of research, details of this process remain mysterious. Here the authors focus on the influence of inertial effects on the self-similar process leading to divergent growth. Asymptotic analysis and numerical simulations reveal a multiplicity of tip configurations that may help to explain decades-old observations of tip pulsation, droplet emission, liquid recoil, and collapse.

Electromagnetic resonances offering high quality factors (and thus giant enhancement of electromagnetic field) are important in applied physics, yet most of these resonances reside outside the radiative continuum. This study uses a magnetic dipole type of quasi-bound state in the continuum (quasi-MDBIC) of a dielectric metasurface to provide resonant enhancement of wireless power transfer (WPT). The factor and mode volume of this quasi-MDBIC can be manipulated to facilitate the WPT of single and multiple receivers. This result might have great impact in enhancing electromagnetic field-matter interaction to realize WPT.

Lorentz transmission electron microscopy (LTEM) is frequently used to image magnetic induction maps of topological magnetic spin structures. These induction maps are visually intuitive, but can be misinterpreted for materials in which the magnetization differs greatly from the integrated induction, leading to ambiguous determination of spin structures. The authors present PyLorentz, their open-source software for simulating LTEM images from three-dimensional micromagnetic simulations. By applying the technique to Néel skyrmions, they demonstrate that combining simulated and experimental LTEM images gives a more complete picture of complex spin structures.

Riding a different wave: This study shows that an acoustic metasurface can be a platform to implement airborne surface acoustic waves (SAWs) for analog computing based on a quantum algorithm. The authors’ gradient-index acoustic system can be used to perform the Grover search algorithm, with quadratic speedup over classical searches. Such a SAW-based computing system would offer—in the foreseeable future—a flexible platform for analog simulation of quantum algorithms, which could find application in on-chip integrated acoustic and phononic devices.
