Photonic Band Structure of Two-dimensional Atomic Lattices
Janos Perczel, Johannes Borregaard, Darrick E. Chang +4
Two-dimensional atomic arrays exhibit a number of intriguing quantum optical phenomena, including subradiance, nearly perfect reflection of radiation and long-lived topological edg…
Probing many-body dynamics on a 51-atom quantum simulator
Hannes Bernien, Sylvain Schwartz, Alexander Keesling +9
Controllable, coherent many-body systems can provide insights into the fundamental properties of quantum matter, enable the realization of new quantum phases and could ultimately l…
Delayed Coherent Quantum Feedback from a Scattering Theory and a Matrix Product State Perspective
Pierre-Olivier Guimond, Mikhail Pletyukhov, Hannes Pichler +1
We study the scattering of photons propagating in a semi-infinite waveguide terminated by a mirror and interacting with a quantum emitter. This paradigm constitutes an example of c…
Quantum Spin Lenses in Atomic Arrays
A. W. Glaetzle, K. Ender, D. S. Wild +4
We propose and discuss `quantum spin lenses', where quantum states of delocalized spin excitations in an atomic medium are `focused' in space in a coherent quantum process down to…
Topological Quantum Optics in Two-Dimensional Atomic Arrays
Janos Perczel, Johannes Borregaard, Darrick E. Chang +4
We demonstrate that two-dimensional atomic emitter arrays with subwavelength spacing constitute topologically protected quantum optical systems where the photon propagation is robu…
Photonic tensor networks produced by a single quantum emitter
Hannes Pichler, Soonwon Choi, Peter Zoller +1
We propose and analyze a protocol to generate two dimensional tensor network states using a single quantum system that sequentially interacts with a 1D string of qubits. This is ac…
