Universality of Hofstadter butterflies on hyperbolic lattices
Alexander Stegmaier, Lavi K. Upreti, Ronny Thomale +1
Motivated by recent experimental breakthroughs in realizing hyperbolic lattices in superconducting waveguides and electric circuits, we compute the Hofstadter butterfly on regular…
Simulating hyperbolic space on a circuit board
Patrick M. Lenggenhager, Alexander Stegmaier, Lavi K. Upreti +12
The Laplace operator encodes the behavior of physical systems at vastly different scales, describing heat flow, fluids, as well as electric, gravitational, and quantum fields. A ke…
Circuit Quantum Electrodynamics in Hyperbolic Space: From Photon Bound States to Frustrated Spin Models
Przemyslaw Bienias, Igor Boettcher, Ron Belyansky +2
Circuit quantum electrodynamics is one of the most promising platforms for efficient quantum simulation and computation. In recent groundbreaking experiments, the immense flexibili…
Protocols for estimating multiple functions with quantum sensor networks: geometry and performance
Jacob Bringewatt, Igor Boettcher, Pradeep Niroula +2
We consider the problem of estimating multiple analytic functions of a set of local parameters via qubit sensors in a quantum sensor network. To address this problem, we highlight…
Crystallography of Hyperbolic Lattices
Igor Boettcher, Alexey V. Gorshkov, Alicia J. Kollár +3
Hyperbolic lattices are a revolutionary platform for tabletop simulations of holography and quantum physics in curved space and facilitate efficient quantum error correcting codes.…
