Engineers at Northwestern University have demonstrated quantum teleportation over a fiber optic cable already carrying Internet traffic. This feat, published in the journal Optica, opens up new possibilities for combining quantum communication with existing Internet infrastructure. It also has major implications for the field of advanced sensing technologies and quantum computing applications.
Quantum teleportation, a process that harnesses the power of quantum entanglement, enables an ultra-fast and secure method of information sharing between distant network users. Unlike traditional communication methods, quantum teleportation does not require the physical transmission of particles. Instead, it relies on entangled particles exchanging information over great distances.
Nobody thought it would be possible to achieve this, according to Professor Prem Kumar, who led the study. “Our work shows a path towards next-generation quantum and classical networks sharing a unified fiber optic infrastructure. Basically, it opens the door to pushing quantum communications to the next level.”
The speed of the human brain’s ability to process information has been investigated in a new study, and according to scientists, we’re not as mentally quick as we might like to think.
In fact, research suggests our brains process information at a speed of just 10 bits per second. But how is this possible, in comparison to the trillions of operations computers can perform every second?
Research suggests this is the result of how we internally process thoughts in single file, making for a slow, congested queue.
An experiment showing that quantum and classical communication can be carried out through the same fibre at the same time may open the door to building a quantum internet with existing infrastructure.

“The challenge is applying agentic AI in the enterprise setting or in innovation-driven industries, like materials science R&D or pharma, where there is higher uncertainty and risk,” said Connell. “These more complex environments require a very nuanced understanding by the agent in order to make trustworthy, reliable decisions.”

As with analytical and gen AI, data — particularly real-time data — is at the core of agentic AI success. It’s important “to have an understanding of how agentic AI will be used and the data that is powering the agent, as well as a system for testing,” said Connell. “To build AI agents, you need clean and, for some applications, labeled data that accurately represents the problem domain, along with sufficient volume to train and validate your models.”
The brain is sometimes called the most complex machine in the known universe. But the thoughts that it outputs putter along at a trifling 10 bits per second, the pace of a conversation.

People tend to have the sense that their inner thoughts and feelings are much richer than what they are capable of expressing in real time. Elon Musk has spoken publicly about this “bandwidth problem,” as he described it to podcaster Joe Rogan. Musk is so bothered by this, in fact, that he has made it one of his long-term goals to create an interface that allows the human brain to communicate directly with a computer, unencumbered by the slow speed of speaking or writing.
Caltech researchers have quantified the speed of human thought: a rate of 10 bits per second. However, our bodies’ sensory systems gather data about our environments at a rate of a trillion bits per second, which is 100 million times faster than our thought processes. This new study raises major new avenues of exploration for neuroscientists, in particular: Why can we only think one thing at a time while our sensory systems process thousands of inputs at once?
The research was conducted in the laboratory of Markus Meister, the Anne P. and Benjamin F. Biaggini Professor of Biological Sciences, and it was led by graduate student Jieyu Zheng. A paper describing the study appears in the journal Neuron.
A bit is a basic unit of information in computing. A typical Wi-Fi connection, for example, can process 50 million bits per second. In the new study, Zheng applied techniques from the field of information theory to a vast amount of scientific literature on human behaviors such as reading and writing, playing video games, and solving Rubik’s Cubes, to calculate that humans think at a speed of 10 bits per second.
