Topological modes are special ways for light to propagate within a structure, which have overall properties that render the modes immune to imperfections, such as in superlattices. This robustness, however, comes with limited scale. UCF researchers have managed to utilize quantum entanglement to circumvent this issue.
“We have figured out a way to entangle the topological protected modes of superlattices,” Andrea Blanco-Redondo says. “What we have shown with this new method is a scalable way to generate more and more complex entangled states, maintaining topological protection of those entangled states.” This increases both the capacity and robustness of quantum systems, both crucial to the future of quantum computing.
