Algorithms have been used throughout the world’s civilizations to perform fundamental operations for thousands of years. However, discovering algorithms is highly challenging. Matrix multiplication is ...

Mathematicians love a good puzzle. Even something as abstract as multiplying matrices (two-dimensional tables of numbers) can feel like a game when you try to find the most efficient way to do it.

Aalto University has demonstrated Tensor calculations using light. “Tensor operations are the kind of arithmetic that form the backbone of nearly all modern technologies, especially artificial ...
