Tuning color centers at a twisted interface

Kavli Affiliate: Michael Crommie | First 5 Authors: Cong Su, Fang Zhang, Salman Kahn, Brian Shevitski, Jingwei Jiang | Summary: Color center is a promising platform for quantum technologies, but their application is hindered by the typically random defect distribution and complex mesoscopic environment. Employing cathodoluminescence, we demonstrate that an ultraviolet-emitting single photon emitter can […]

Decodable hybrid dynamics of open quantum systems with Z_2 symmetry

Kavli Affiliate: Matthew P. A. Fisher | First 5 Authors: Yaodong Li, Matthew P. A. Fisher, , , | Summary: We explore a class of "open" quantum circuit models with local decoherence ("noise") and local projective measurements, each respecting a global Z_2 symmetry. The model supports a spin glass phase where the Z_2 symmetry is […]

Two-photon sideband transition in a driven quantum Rabi model : Quantitative discussions with derived longitudinal drives and beyond the rotating wave approximation

Kavli Affiliate: Gary A. Steele | First 5 Authors: Byoung-moo Ann, Wouter Kessels, Gary A. Steele, , | Summary: In this work, we analytically and numerically study the sideband transition dynamics of the driven quantum Rabi model (QRM). We focus in particular on the conditions when the external transverse drive fields induce first-order sideband transitions. […]
