In Association With the Journal Optica, Protecting Quantum Data From Turbulence — With Aaron Cardoso
"All Things Photonics" is teaming up with the journal Optica to bring you insights on the latest studies leading to breakthroughs in optics and photonics. Quantum key distribution (QKD) allows encrypted information to be distributed without being intercepted. In free-space QKD, however, fluctuations in atmospheric conditions can cause distortions and impair the retrieval of the encoded information. In a study published in the journal Optica, a research team from the University of Ottawa developed a way to alleviate the effects of atmospheric turbulence on spatial mode transmission, creating an all-optical self-correction scheme for turbulence resilience using stimulated parametric down-conversion (StimPDC)-based optical phase conjugation. Aarón Cardoso, a researcher at the University of Ottawa, joins us to explain why he turned to StimPDC to solve this quantum quandary.

Science in the U.S. after 1 Year of Trump — With Dan Garisto, Freelance Physics Journalist
Every White House administration has its priorities. Government reform and the elimination of waste are among President Donald Trump's top priorities. Cutting down on waste is not a partisan issue; no one wants to throw away money. But how you define waste can draw a mixed response. The president has targeted scientific grants as an area in need of reform, and according to a piece published by Nature, more than 7,800 grants have been terminated or frozen. Dan Garisto is a freelance physics journalist and is one of the three authors of this piece. On this episode of All Things Photonics, he discusses the biggest findings of his work as he dug into the status of U.S. science one year into the president’s second term.

Post-Quantum Optical Security – With Dan Sadot, Founder & CEO of CyberRidge
Online crooks commit what’s called “harvest-now-decrypt-later” attacks to record data in transit to later decode for all the valuable information. There is a way to stop it, but it takes more than some antivirus software. CyberRidge is a photonic encryption technology and security startup. Its flagship product is a plug-and-play photonic-layer transmission system that integrates with existing fiber to transform your data into encrypted noise as it travels to its destination. In this episode, we’ll chat with Dan Sadot, the founder and CEO of CyberRidge. He shares his thoughts on the crimes driving demand for this tech, the groups likely to use it, and the finer points of post-quantum optical security for data in transit.

National Security and Laser Communication — With Dalius Petrulionis
The interference with satellites actively in use for military operations is a real threat to security and civilian safety. But laser communication could provide a deployable solution to the front lines. Unlike radio-frequency links, laser terminals use narrowly focused optical beams that are difficult to jam or intercept. Pairing lasers with existing systems could prove to be unstoppable. Astrolight, a Lithuanian space and defense company, has already deployed terminals used by NATO forces. In this episode, Dalius Petrulionis, co-founder and CTO of Astrolight, discusses how lasers are advancing communication technology and the real-world turmoil that is driving demand for these systems.
