Our latest research on a new class of quantum detectors is published in New Journal of Physics. Here, we propose the "photon discerner", a device which uses adaptive photon thresholding for photon statistical estimation without recording exact photon numbers. We show that the adaptivity of our...

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...

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...

In our recent work in Optics Express, we discover the quantum analog of the well-known classical maximum power transfer theorem, typically used in classical circuit design. By developing a unified framework, from the Lindblad master equation and describing power delivery in dissipative quantum...

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...
