Chinese researchers have developed a new optical transmission system that combines high speed and quantum security. The technology, published in the journal Advanced Photonics, promises to shield Artificial Intelligence data centers against future threats and support the growing demand for data.
How does this new technology work?
It uses a special type of fiber optic cable with multiple internal “tracks”. On a track, ordinary data travels at very high speed. In another, separate space, security keys created with quantum technology travel. This allows information to be protected without causing interference or slowness, solving a major technical challenge.
What is “quantum security” and why is it important?
It is a method of creating encryption “secret keys” that are virtually unbreakable. Quantum physics ensures that any attempt to spy on or copy the key will change its state, warning of intrusion. This is critical to protecting today’s data against future quantum computers, which will have the power to break the encryption we currently use.
What were the practical results of the experiment?
In tests, the system transmitted data at 2 terabits per second while stably generating quantum keys. The number of keys created in 24 hours would be capable of protecting such a large volume of data that it would be equivalent to downloading the entire Netflix catalog more than 20 times in just one second.
Why is this innovation needed now?
The explosive growth of Artificial Intelligence is creating a huge demand for speed and data traffic, and current infrastructure may not support this volume in the future. Furthermore, the new technology is more efficient, which can help reduce the enormous energy and water consumption of data centers running AI applications.
What are the next challenges for the area?
The main challenge is to deepen studies to make the technology viable on a large scale. Although innovation is an advance, the industry as a whole still needs to find solutions to the high environmental cost of AI, such as the consumption of natural resources and the impact generated by the construction of large data center complexes.
