Non-Hermitian skin effect survives decoherence in quantum simulations

The non-Hermitian skin effect, a phenomenon in which all eigenstates of a non-Hermitian system pile up at its boundaries, survives decoherence in simulations carried out with quantum devices. The robustness of the effect against environmental noise matters because many open systems, from photonic circuits to atomic chains, are intrinsically non-Hermitian and operate far from perfect isolation.

Physics World publishes its weekly science news quiz

Physics World has published its weekly quiz, a short piece with which the British outlet invites readers to test how closely they have followed the past week's physics news. The feature runs every week and serves as a light refresher for students, enthusiasts and professionals alike.

The format is straightforward: a series of multiple-choice questions on recent events in the discipline, from experimental results to science policy and life in the labs. The question that gives this edition its title, for example, asks for the name of a committee that seeks to get STEM-educated Democratic candidates into public office, an example of the kind of contextual question that sits alongside the purely technical ones.
