The Revolution of Light: Aristotle University Breaks World Record for AI Computational Power

Thessaloniki, December 9, 2025

In an era where the global tech community is desperately seeking solutions to overcome the physical limitations of silicon and electricity, the School of Informatics at Aristotle University of Thessaloniki (AUTH) announces an achievement that redefines the rules of the game. Emerging from the labs of AUTH is the world’s most powerful photonic Artificial Intelligence (AI) processor, placing Greece at the cutting edge of research for next-generation computational power.

 
Data-Driven Analysis: The Dominance of Numbers

To understand the magnitude of this success, one must speak the language of data. The new chip from AUTH is not merely an improvement; it is a quantum leap.

The processor achieves a computational power of 262 TOPS ($262 \times 10^{12}$ operations per second). This figure constitutes a world record among all fully programmable AI tensor cores.

Comparatively, the system’s supremacy is illustrated as follows:

  • Research Prototypes: It is approximately 24 times faster than any other corresponding experimental fully programmable photonic processor prototype reported worldwide.
  • Industry Giants: It is approximately 10 times more powerful than NVIDIA’s most powerful Artificial Intelligence tensor core, the B200.

 
Technological Innovation: Multiplexing in Three Dimensions

The strategic differentiation of the Greek research team lies in changing the medium of information transport: from electric current to light. The processor employs photonic neurons, implementing a novel architecture that enables high-speed algebraic operations.

The “secret” to its performance lies in exploiting multiplexing along three dimensions:

  1. Time
  2. Space
  3. Wavelength.

This three-dimensional approach addresses one of the most critical challenges in modern computing: the ability to support Large AI Models with hardware capable of meeting their enormous demands.

 

Strategic Collaboration: The “Ecosystem” of Success

This success is not accidental but the result of a strategic interdisciplinary collaboration within the School of Informatics. Two leading research groups joined forces:

  • The WinPhoS (Wireless and Photonic Systems and Networks) group, led by Professor Nikos Pleros.
  • The CIDL (Computational Intelligence and Deep Learning) group, led by Professor Anastasios Tefas, with key collaborator Assistant Professor Nikolaos Passalis.

This partnership between Hardware (photonics) and Software (deep learning algorithms) proves that innovation now requires a holistic approach.

 

International Recognition and Funding from Silicon Valley

The scope of the project extends beyond Greek borders, attracting interest and capital from the global industry. In addition to European (Horizon) and national programs, the research is funded by the US start-up Celestial AI, based in Silicon Valley and recently acquired by Marvell.

Concurrently, AUTH’s human capital is receiving top-tier distinctions:

  • Lead researcher Christos Pappas was distinguished by the IEEE Photonics Society as one of the top 10 PhD candidates worldwide for 2025.
  • Dr. Apostolos Tsakyridis has been invited to present the results at the Optical Fiber Communication Conference (OFC) in Los Angeles in March 2026.

 
Conclusion: Greece on the High-Tech Map

The announcement of December 9, 2025, confirms that the Greek public university can produce cutting-edge innovation. AUTH is not just following developments but shaping them, offering the highest recorded computational power worldwide in programmable photonic processors16. In a world thirsting for speed and energy efficiency in AI, the solution comes from Thessaloniki, traveling at the speed of light.
