What do encrypted messages, recognizing speech commands and running simulations to predict the weather have in common? They all rely on matrix multiplication for accurate calculations. DeepMind, an ...

A 20-year-old algorithm that demonstrated the benefit of using quantum mechanics to solve certain problems has finally been run on a quantum computer. Simon’s algorithm, proposed by computer scientist ...

For decades, the graph isomorphism problem has held a special status within complexity theory. While thousands of other computational problems have meekly succumbed to categorization as either hard or ...

Childs has been recognised for his contributions to quantum simulation and Hamiltonian dynamics. His work has focused on developing fast quantum algorithms for simulating Hamiltonian dynamics, which ...

The original version of this story appeared in Quanta Magazine. One July afternoon in 2024, Ryan Williams set out to prove himself wrong. Two months had passed since he’d hit upon a startling ...

“LET’S do it again,” calls a ten-year-old. Once more, pupils clasping printed numbers follow tangled lines marked with white tape on the floor of their school hall. When two meet, the one holding the ...
