Scientists Uncover Hidden Weakness in Quantum Encryption
Quantum key distribution (QKD) is a next generation method for protecting digital communications by drawing on the fundamental behavior of quantum particles. Instead of relying on mathematical complexity alone, QKD allows two users to establish a shared secret key in a way that is inherently resistant to interception, even if the communication channel itself is not private.
When an unauthorized observer attempts to extract information, the quantum states carrying the data are unavoidably altered, creating telltale disturbances that signal a potential security breach.
The real-world performance of QKD systems, however, depends on precise control of the physical link between sender and receiver. One of the most influential factors is pointing error, which occurs when the transmitted beam does not perfectly align with the receiving device.
Who’s behind AMI Labs, Yann LeCun’s ‘world model’ startup
Yann LeCun’s new venture, AMI Labs, has drawn intense attention since the AI scientist left Meta to found it. This week, the startup finally confirmed what it’s building — and several key details have been hiding in plain sight.
On its newly launched website, the startup disclosed its plans to develop “world models” in order to “build intelligent systems that understand the real world.” The focus on world models was already hinted at by AMI’s name, which stands for Advanced Machine Intelligence, but it has now officially joined the ranks of the hottest AI research startups.
Building foundational models that bridge AI and the real world has become one of the field’s most exciting pursuits, attracting top scientists and deep-pocketed investors alike — product or no product.
