Realizing distance-selective interactions in a Rydberg-dressed atom array
Simon Hollerith, Kritsana Srakaew, David Wei +10
Measurement-based quantum computing relies on the rapid creation of large-scale entanglement in a register of stable qubits. Atomic arrays are well suited to store quantum informat…
Microwave-optical coupling via Rydberg excitons in cuprous oxide
Liam A. P. Gallagher, Joshua P. Rogers, Jon D. Pritchett +9
We report exciton-mediated coupling between microwave and optical fields in cuprous oxide (CuO) at low temperatures. Rydberg excitonic states with principal quantum number up t…
Superglass formation in an atomic BEC with competing long-range interactions
Stefan Ostermann, Valentin Walther, Susanne F. Yelin
The complex dynamical phases of quantum systems are dictated by atomic interactions that usually evoke an emergent periodic order. Here, we study a quantum many-body system with tw…
Photon control and coherent interactions via lattice dark states in atomic arrays
Oriol Rubies-Bigorda, Valentin Walther, Taylor L. Patti +1
Ordered atomic arrays with subwavelength spacing have emerged as an efficient and versatile light-matter interface, where emitters respond collectively and form subradiant lattice…
Simulation of many-body dynamics using Rydberg excitons
Jacob Taylor, Sumit Goswami, Valentin Walther +3
The recent observation of high-lying Rydberg states of excitons in semiconductors with relatively high binding energy motivates exploring their applications in quantum nonlinear op…
Correlated many-body noise and emergent behavior in an anharmonic fluctuator model
P N Thomas Lloyd, Valentin Walther, Hossein Sadeghpour
Fluctuating electric fields emanating from surfaces are a primary source of decoherence in trapped ion qubits. Here, we show that superradiant phonon-induced excitation exchange be…
Nonclassical Light from Exciton Interactions in a Two-Dimensional Quantum Mirror
Valentin Walther, Lida Zhang, Susanne F. Yelin +1
Excitons in a semiconductor monolayer form a collective resonance that can reflect resonant light with extraordinarily high efficiency. Here, we investigate the nonlinear optical p…
Photon-photon interactions in Rydberg-atom arrays
Lida Zhang, Valentin Walther, Klaus Mølmer +1
We investigate the interaction of weak light fields with two-dimensional lattices of atoms, in which two-photon coupling establishes conditions of electromagnetically induced trans…
