We’re founding a quantum-thermodynamics hub!

We’re building a factory in Maryland.&

It’ll tower over the University of Maryland campus, a behemoth of 19th-century brick and 21st-century glass across from the football field. Turbines will turn, and gears will grind, where students now sip lattes near the Stadium Drive parking lot. The factory’s fuel: steam, quantum physics, and ambition. Its goal: to create an epicenter for North American quantum thermodynamics.

The factory is metaphorical, of course. Collaborators and I are establishing a quantum-thermodynamics hub centered at the University of Maryland. The hub is an abstraction—a community that’ll collaborate on research, coordinate gatherings, host visitors, and raise the public’s awareness of quantum thermodynamics. But I’d rather envision the hub as a steampunk factory that pumps out discoveries and early-career scientists.

Quantum thermodynamics has burgeoned over the past decade, especially in Europe. At the beginning of my PhD, I read paper after paper that acknowledged COST, a funding agency established by the European Union. COST dedicated a grant to thermodynamics guided by the mathematics and concepts of quantum information theory. The grant funded students, travel, and the first iterations of an annual conference that continues today. Visit Germany, Finland, France, Britain (which belonged to the European Union when I began my PhD), or elsewhere across the pond, and you’ll stumble across quantum-thermodynamics strongholds. Hotspots burn also in Brazil, Israel, Singapore, and elsewhere.

Inspired by our international colleagues, collaborators and I are banding together. Since I founded a research group last year, Maryland has achieved a critical mass of quantum thermodynamicists: Chris Jarzynski reigns as a king of the field of fluctuation relations, equalities that help us understand why time flows in only one direction. Sebastian Deffner, I regard as an academic older brother to look up to. And I run the Quantum-Steampunk Laboratory.

We’ve built railroads to research groups across the continent and steamers to cross the ocean. Other members of the hub include Kanu Sinha, a former Marylander who studies open systems in Arizona; Steve Campbell, a Dublin-based prover of fundamental bounds; and two experts on quantum many-body systems: former Marylander Amir Kalev and current Marylander Luis Pedro García-Pintos. We’re also planning collaborations with institutions from Canada to Vienna.

The hub will pursue a threefold mission of research, community building, and outreach. As detailed on our research webpage, “We aim to quantify how, thermodynamically, decoherence and the spread of information lead to emergent phenomena: classical objectivity and the flow of time.” To grow North America’s quantum-thermodynamics community, we’ll run annual symposia and an international conference. Our visitors’ program will create the atmosphere of a local watering hole. Outreach will include more posts on this blog—including by guest authors—a quantum-steampunk short-story contest (expect details this fall), and more.

Come visit us by dirigible, train, or gyropter. Air your most thought-provoking quantum-thermodynamics discoveries in a seminar with us, and solicit feedback. Find collaborators, and learn about the latest. The factory wheels are beginning to turn.

With thanks to the John Templeton Foundation for the grant to establish the hub.
