Symmetry breaking and error correction in open quantum systems
Simon Lieu, Ron Belyansky, Jeremy T. Young +3
Symmetry-breaking transitions are a well-understood phenomenon of closed quantum systems in quantum optics, condensed matter, and high energy physics. However, symmetry breaking in…

Quantum Simulation of Hyperbolic Space with Circuit Quantum Electrodynamics: From Graphs to Geometry
Igor Boettcher, Przemyslaw Bienias, Ron Belyansky +2
We show how quantum many-body systems on hyperbolic lattices with nearest-neighbor hopping and local interactions can be mapped onto quantum field theories in continuous negatively…

Nondestructive cooling of an atomic quantum register via state-insensitive Rydberg interactions
Ron Belyansky, Jeremy T. Young, Przemyslaw Bienias +4
We propose a protocol for sympathetically cooling neutral atoms without destroying the quantum information stored in their internal states. This is achieved by designing state-inse…
