成人VR视频 and Queen鈥檚 University researchers have built an improved version of a computer that uses light to solve extremely hard problems more quickly and at larger scale than existing systems, without the need for cryogenic cooling.

"This exponential scaling is a major bottleneck for progress in several fields,鈥� said David Plant, Tier I Canada Research Chair, and senior author of the study published in Nature and a professor of electrical engineering at 成人VR视频.

The team built a photonic Ising machine 鈥� a non-traditional computing system that models complex problems using the physics of light. Unlike other non-traditional computing approaches that struggle with scaling, stability or the need for cryogenic operation, this photonic Ising machine runs at room temperature and is designed to remain stable as problems scale up.

鈥淲e built the entire photonic Ising machine,鈥� Charles St. Arnault, lead 成人VR视频 Ph.D. student said. 鈥淭his involved putting together multiple ultra-sensitive components, writing completely novel control algorithms, and digital signal processing to keep the system stable. We found that those signal processing algorithms sped up the computation, reducing the number of iterations required to reach the optimal solution.鈥�

鈥淭his research matters because it opens a path to solving complex problems much faster, at lower cost and with less consumed power. The new photonic Ising machine runs at very high speed, at room temperature, and scales to problem sizes that were previously out of reach, even for quantum devices.鈥�
