Collective Strong Coupling of Thermal Atoms to Integrated Microring Resonators
Xiaoyu Cheng, Benyamin Shnirman, Alexandra Köpf +5
Strong coupling between atomic ensembles and high-quality optical cavities enables collective and nonlinear phenomena that are central to cavity quantum electrodynamics (cQED). Alt…
Collective Enhancement of Photon Blockade via Two-Photon Interactions
Lijuan Dong, Aanal Jayesh Shah, Peter Kirton +2
Analogous to Coulomb blockade for electrons, photon blockade is a key quantum optical effect in which the presence of one photon prevents the transmission of subsequent ones throug…
Engineering nonlinear activation functions for all-optical neural networks via quantum interference
Ruben Canora, Xinzhe Xu, Ziqi Niu +2
All-optical neural networks (AONNs) promise transformative gains in speed and energy efficiency for artificial intelligence (AI) by leveraging the intrinsic parallelism and wave na…
Cooperative Effects in Thin Dielectric Layers: Long-Range Dicke Superradiance
Ankit Kundu, Rahul Trivedi, Alisa Javadi +1
The realization and control of collective effects in quantum emitter ensembles have predominantly focused on small, ordered systems, leaving their extension to larger, more complex…
Dissipative Phase Transition in the Two-Photon Dicke Model
Aanal Jayesh Shah, Peter Kirton, Simone Felicetti +1
We explore the dissipative phase transition of the two-photon Dicke model, a topic that has garnered significant attention recently. Our analysis reveals that while single-photon l…
Single-Photon Generation: Materials, Techniques, and the Rydberg Exciton Frontier
Arya Keni, Kinjol Barua, Khabat Heshami +2
Due to their quantum nature, single-photon emitters generate individual photons in bursts or streams. They are paramount in emerging quantum technologies such as quantum key distri…
