Consequently, traditional electronic chips are unlikely to deliver significant improvements in performance.
The Lightmatter device, which is approximately the size of a computer keyboard, is equipped with four photonic chips that use light to perform matrix multiplication. With over 200,000 components manipulating 512 light beams, this device can outperform typical electronic chips in terms of speed and efficiency. On the other hand, the Lightelligence device, known as PACE, combines photonic and electronic chips to accelerate computation for optimization problems crucial in industries such as finance, manufacturing, and shipping.
In a groundbreaking achievement, the Lightmatter team successfully ran mainstream AI models, including large language models like ChatGPT and Claude, on their light-based processor. They also tested a deep learning algorithm playing Atari games, including Pac-Man. These accomplishments underscore the potential of photonic computing to revolutionize the field of computing and address the challenges posed by the limitations of traditional electronic chips.
The convergence of light-based computing and traditional electronics opens up new possibilities for faster, more energy-efficient computing. With the rapid advancement of these technologies, the future of computing looks promising, paving the way for innovative solutions to complex computational problems. Engineers have been working on experimental photonic processors for some time now, but they have always fallen short when it comes to matching the performance of traditional computers on real-world computing problems. One of the biggest issues with these processors has been accuracy. Light signals in photonic processors can take on a wide range of values, which can lead to errors in calculations if not transmitted correctly.
However, Lightelligence, a company specializing in photonic processors, has made a breakthrough in this area. By stacking electronic chips on top of their photonic ones, they have been able to carefully control the incoming and outgoing data, reducing errors and improving accuracy. This new processor is not just a lab prototype, but a fully functional computer that is ready for use.
In optimization problems, some randomness can be beneficial as it helps the system explore solutions more efficiently. Lightmatter has taken this into account in their design, ensuring that their processor can handle these types of problems with ease. The photonic components for their devices can be manufactured using the same processes that already produce electronic chips, making it easy to scale up production. This means that these new photonic processors could be integrated into data centers within the next five years.
With this new technology on the horizon, the future of computing looks brighter than ever. Photonic processors have the potential to revolutionize the way we approach computing problems, offering faster and more efficient solutions. As Lightelligence continues to push the boundaries of what is possible with photonic processors, we can expect to see even more exciting developments in the years to come.
