Looking for a layman's summary of this article. If I spent a couple of hours maybe I could do it. Then again, maybe not.

This article discusses the development of a new device that can measure the movement of particles at the nanoscale. This device, known as an ion trap, uses electric fields to trap and measure the motion of ions (charged atoms). The article explains how this approach could be used to accurately measure the mass of single ions and how it can be used to study the physics of individual particles. It also describes the potential applications of such measurements, including the study of exotic particles, the development of improved sensors, and the understanding of quantum mechanics. Ultimately, this new device could open up new possibilities in the fields of physics, chemistry, and biology.
 
Not an expert in QM. AFAIK, Schrödinger's equation is quite different from the classical wave equation. The former is an equation for the dynamics of the state of a (quantum?) system, the latter is an equation for the dynamics of a (classical) degree of freedom. As a matter of fact, Schrödinger's equation is first order in time derivatives, while the classical wave equation is second order. But, AFAIK, Schrödinger's equation is a wave equation; only its interpretation makes it non-classical...

Is it possible, and fruitful, to use certain conceptual and technical tools from effective field theory (coarse-graining/integrating-out, power-counting, matching, RG) to think about the relationship between the fundamental (quantum) and the emergent (classical), both to account for the quasi-autonomy of the classical level and to quantify residual quantum corrections? By “emergent,” I mean the following: after integrating out fast/irrelevant quantum degrees of freedom (high-energy modes...
