![Quantum entanglement. Conceptual artwork of a pair of entangled quantum particles or events (left and right) interacting at a distance. Quantum entanglement is one of the consequences of quantum theory. Two particles will appear to be linked across space and time, with changes to one of the particles (such as an observation or measurement) affecting the other one. This instantaneous effect appears to be independent of both space and time, meaning that, in the quantum realm, effect may precede cause.](https://images.newscientist.com/wp-content/uploads/2023/04/19183514/SEI_151937476.jpg?width=300)

Karmela Padavic-Callaghan is a science writer reporting on physics, materials science and quantum technology. Karmela earned a PhD in theoretical condensed matter physics and atomic, molecular, and optical physics from the University of Illinois Urbana Champaign and her research has been published in peer reviewed journals including Physical Review Letters and New Journal of Physics.
She studied ultracold atomic systems in novel geometries in microgravity and the interplay of disorder and quasiperiodicity in one-dimensional systems, including metamaterials. During her doctoral training she also participated in several art-based projects including co-developing a course on physics and art and serving as a production manager for a devised theatre piece title Quantum Voyages.
Before joining the New Scientist, Karmela was an Assistant Professor at Bard High School Early College in New York City where she taught high-school and college courses in physics and mathematics. Karmela’s freelance writing has been featured in Wired, Scientific American, Slate, MIT Technology Review, Quanta Magazine and Physics World.
