Hyperbolic Poincare Projection
The field of circuit QED has emerged as a rich platform for both quantum computation and quantum simulation. Lattices of coplanar waveguide (CPW) resonators realize artificial photonic materials in the tight-binding limit. Combined with strong qubit-photon interactions, these systems can be used to study dynamical phase transitions, many-body phenomena, and spin models in driven-dissipative systems. These waveguide cavities are uniquely deformable and can produce lattices and networks which cannot readily be obtained in other systems, including periodic lattices in a hyperbolic space of constant negative curvature, and the one-dimensional nature of CPW resonators leads to degenerate flat bands. In our lab, we build experimental implementations of these systems using superconducting circuits.

JQI welcomes four newest Fellows
JQI has named four new Fellows in 2019, bringing the total number to 35. All four of the new arrivals have appointments in the Department of Physics at the University of Maryland. One Fellow is also a professor in the Department of Electrical and Computer Engineering at UMD and another is a physicist at the National Institute of Standards and Technology (NIST).
