Replacing traditional computer chip components with light-based counterparts will eventually make electronic devices faster due to the wide bandwidth of light. A new protective metamaterial "cladding" prevents light from leaking out of the very curvy pathways it would travel in a computer chip.

Researchers at the University of Alberta, Canada, have proposed a new approach to confining light at subdiffraction wavelengths, using transparent metamaterials—without creating heat or losing data, and with dramatically reduced crosstalk.

Zubin Jacob gives invited talk at Rice University quantum seminar “New directions in quantum sensing: Photonic spin density and atomistic topological electrodynamics”. Nitrogen vacancy (NV) centers in diamond have emerged as promising room temperature quantum sensors for probing condensed matter...

Wenbo Sun received the Outstanding Graduate Student Research Award in recognition of his excellence in graduate student research. The award was conferred at the Purdue College of Engineering Graduate Education Awards 2024 luncheon on April 17th, . This is awarded to 13 Ph.D. students (2 from ECE)...

There is a long way to go before quantum information (QI) can have a real-world impact on machine learning applications. However, in the short term, QI presents a principled approach to unravel performance bounds and find hidden quantum-classical parallels for widely used machine learning algorithms...

Congratulations to Mohammad Ali Javidian on the selection of his paper titled “Tensor Rings for Learning Circular Hidden Markov Models” which was virtually presented at the second Workshop on Quantum Tensor Networks in Machine Learning.

Prof Zubin Jacob gave a plenary talk at the physics of quantum electronics conference. He spoke about the recent theory work on Atomistic Maxwell Hamiltonians and the topological optical-N insulator.

Our first speaker was a pioneer in the field of theoretical quantum optics - Prof. John Sipe from the University of Toronto. He talked about the response of solids to incident electromagnetic fields which is often heuristically described in terms of macroscopic polarization and magnetization fields...

Published in PR Applied, our recent work develops the theoretical and computational framework to analyze the spin angular momentum of thermal radiation from bodies with nonuniform temperature profiles. By considering a sample problem of a long silica wire held under a temperature gradient within its...

Prof. Stephan Haas discussed how the many-body excitation spectrum of topological insulators is affected by the presence of long-range Coulomb interactions. In the one-dimensional Su-Schrieffer-Heeger model and its mirror-symmetric variant, strongly localized plasmonic excitations are observed which...
