How to Build a Photonic Quantum Computer
Expectations for quantum computers are high: They are supposed to outperform digital computers and pave the way for solutions that go far beyond the capabilities that artificial intelligence already delivers. They are predicted to crack unbreakable codes, find new materials for superconductors, and help develop medicine for the next pandemic. These are only some of the envisioned outcomes.

Low-Power Lasers Exhibit Narrow Linewidth Needed for Quantum Computing
Using a commercial scanning Fabry-Pérot interferometer, researchers at FLEET, the Australian Research Council’s Center of Excellence in Future Low-Energy Electronics Technologies, investigated the energy and linewidth of exciton-polariton lasers in the single-mode regime. The researchers demonstrated that, contrary to previous assumptions, the exciton-polariton laser can maintain an ultra-narrow linewidth of 56 MHz, or 0.24 microelectronvolts — 10x smaller than previously thought.

New and Improved Skipper CCDs Count Photons from Distant Galaxies
Using an instrument on the 4.1-meter Southern Astrophysical Research Telescope, researchers obtained the first astronomical spectrum using skipper charge-coupled devices. Originally envisioned for this purpose, the technology has been largely limited to the study of charged particles since its introduction in 1990.

SWIR and NIR Disruptive Zoom Lens for Challenging Environments: Air, Land, and Maritime
Thu, Sep 12, 2024 9:00 AM - 10:00 AM EDT
Peter Kunert of MKS Ophir IR Optics explores the advantages of SWIR lenses and how they play a pivotal role in air, land, and maritime imaging, offering unparalleled visibility even in challenging conditions, such as haze, smoke, and fog. Incorporating SWIR and NIR into electro-optical (EO) systems significantly enhances image clarity and performance. SWIR lenses excel in long-range daytime observation, effective glass transmission, and precise laser spot detection for designators, making them an ideal solution for defense and homeland security applications. This presentation shares how SWIR technology can transform an EO system and improve operational efficiency. Presented by MKS Ophir.
