The HNDL threat crypto agility can’t address HNDL attacks pose existential threats to long-lived sensitive data. Adversaries intercept and store encrypted communications today, then decrypt them when quantum computers or cryptanalytic breakthroughs emerge years later. This isn’t theoretical—intelligence agencies have long pursued bulk data collection with precisely this strategy. PQC advocates invoke “crypto agility”—swapping cryptographic […]

For two decades, terahertz technology carried the promise of nondestructive, material-specific insights but remained primarily confined to research labs. The scientific community was impressed with demonstrations of nondestructive, label-free probing through polymers, coatings, and tablets, resolving structures on picosecond timescales, and detecting spectral fingerprints of water and other materials. But the systems were large, alignment-sensitive,

A new diode nanocavity created by a team of researchers at Simon Fraser University (SFU) and quantum company Photonic Inc. in Canada enables optical and electrical control of silicon “color center” qubits. Until now, these qubits, a.k.a. T centers, were controlled optically with lasers. This dual control option of T centers hints at potential applications

Light is the fastest and cleanest carrier of information we know. The science and technology of guiding, manipulating, and detecting light—photonics—underpins every facet of modern life, from the global internet and medical imaging to precision manufacturing and autonomous sensing. For decades, the photonics industry has flourished in an environment of predictability. Much of linear optics

In this episode of Photonics Hot List: Researchers in Portugal have designed an imaging approach that distinguishes between benign and malignant tumors, and could ultimately help clinicians develop more effective treatments. The business sector of the photonics industry is booming with the recent announcements of several mergers and acquisitions. A so-called photonic crystal highway, guiding

A team of researchers led by Professor Anita Ho-Baillie, the John Hooke Chair of Nanoscience at the University of Sydney in Australia, set a new solar technology record for the world’s largest triple-junction perovskite-perovskite-silicon tandem solar cell. Their 16-cm2 triple-junction cell features a steady-state power conversion efficiency of 23.3% (independently certified), which is the highest

AMF’s recent event brought together industry leaders to discuss the ways silicon photonics (SiPh) is maturing from a promising technology into a foundational standard for the next-generation high-speed data infrastructure. The summit’s central theme was SiPh at scale, and it provided a strategic roadmap to advance SiPh technology to meet rapidly accelerating production and unprecedented

In this episode of Photonics Hot List: With a straightforward combination of smartphone LiDAR and a terrestrial laser scanner, a team led by researchers at the University of Seville in Spain can now more accurately document fragile archaeological sites. The 2025 Nobel Prize in Physics has been announced, with a team of professors from the

Augmented reality (AR) glasses and smart glasses have been available for more than a decade, but adoption by the market is moving slowly. Within the past year, smart glasses gained momentum largely driven by the widespread integration of artificial intelligence (AI). The competitive landscape is no longer just about the hardware but is increasingly about

Simulating “warm dense matter” was a roadblock for researchers pursuing a better understanding of this state of matter, but a new approach to Path Integral Monte Carlo (PIMC) simulations by researchers from the Center for Advanced Systems Understanding (CASUS) at the Helmholtz Zentrum Dresden-Rossendorf in Germany and Lawrence Livermore National Laboratory (LLNL) is finally revealing
