In December, OpenAI announced a partnership with defense tech startup Anduril to deploy advanced AI systems for “national security missions.”

Quantum mechanics provide truly random numbers on demand
Randomness is incredibly useful. People often draw straws, throw dice or flip coins to make fair choices. Random numbers can enable auditors to make completely unbiased selections. Randomness is also key in security; if a password or code is an unguessable string of numbers, it’s harder to crack. Many of our cryptographic systems today use random number generators to produce secure keys.
But how do you know that a random number is truly random?
Classical computer algorithms can only create pseudorandom numbers, and someone with enough knowledge of the algorithm or the system could manipulate it or predict the next number. An expert in sleight of hand could rig a coin flip to guarantee a heads or tails result. Even the most careful coin flips can have bias; with enough study, their outcomes could be predicted.
Mind-Blowing Speed of Quantum Entanglement Measured for the First Time
In a monumental breakthrough, scientists have measured the speed of quantum entanglement for the first time—an achievement that is set to radically transform the way we understand the quantum world. For years, quantum entanglement was thought to be an instantaneous process, but this new research, published in Physical Review Letters, has pushed the boundaries of our knowledge, providing new insights into the quantum realm and setting the stage for revolutionary advances in data security and computational technologies.
Redefining Cyber Value: Why Business Impact Should Lead the Security Conversation
Security teams face growing demands with more tools, more data, and higher expectations than ever. Boards approve large security budgets, yet still ask the same question: what is the business getting in return? CISOs respond with reports on controls and vulnerability counts – but executives want to understand risk in terms of financial exposure, operational impact, and avoiding loss.
The disconnect has become difficult to ignore. The average cost of a breach has reached $4.88 million, according to recent IBM data. That figure reflects not just incident response but also downtime, lost productivity, customer attrition, and the extended effort required to restore operations and trust. The fallout is rarely confined to security.
Security leaders need a model that brings those consequences into view before they surface. A Business Value Assessment (BVA) offers that model. It links exposures to cost, prioritization to return, and prevention to tangible value.
A semi-automated manufacturing process for cost-efficient quantum cascade laser modules
Resonantly tunable quantum cascade lasers (QCLs) are high-performance laser light sources for a wide range of spectroscopy applications in the mid-infrared (MIR) range. Their high brilliance enables minimal measurement times for more precise and efficient characterization processes and can be used, for example, in chemical and pharmaceutical industries, medicine or security technology. Until now, however, the production of QCL modules has been relatively complex and expensive.
The Fraunhofer Institute for Applied Solid State Physics IAF has therefore developed a semi-automated process that significantly simplifies the production of QCL modules with a MOEMS (micro-opto-electro-mechanical system) grating scanner in an external optical cavity (EC), making it more cost-efficient and attractive for industry. The MOEMS-EC-QCL technology was developed by Fraunhofer IAF in collaboration with the Fraunhofer Institute for Photonic Microsystems IPMS.
