Creating Dynamic Symmetry in Quantum Systems

Physicists and engineers have long been interested in creating new forms of matter, those not typically found in nature. Such materials might find use someday in, for example, novel computer chips. Beyond applications, they also reveal elusive insights about the fundamental workings of the universe. Recent work at MIT both created and characterized new quantum systems demonstrating dynamical symmetry — particular kinds of behavior that repeat periodically, like a shape folded and reflected through time.

Improved Quantum Particle Simulations

As studies involving quantum systems are discovering, the environment the systems reside in has substantial impact on particle behavior. Research teams at the University of St. Andrews have reported a new method to simulate quantum computing environments more accurately “even on a regular laptop.” With more complex systems envisioned to produce high-powered quantum computers, better simulations of quantum “many particle” interactions are needed.
