Beyond the Four-Level Model: Dark and Hot States in Quantum Dots Degrade Photonic Entanglement, opens an external URL in a new window, opens an external URL in a new window
Nano Lett. 23, 1409-1415 (2023).
This paper presents a new model for understanding the degradation of photonic entanglement in quantum dots, taking into account the presence of dark and hot states beyond the commonly used four-level model. The study uses simulations to demonstrate how the inclusion of these additional states can significantly impact the entanglement fidelity of quantum dots. The findings provide important insights into the design and optimization of quantum dot-based photonic devices for future quantum communication and information processing applications.
