Quantum walks sound abstract, but they sit at the center of a very concrete race: who will harness quantum mechanics to solve problems that overwhelm today’s most powerful supercomputers. Instead of ...

The age of quantum computers is fast approaching, and with it comes the potential threat of breaking classical encryption. The algorithms that have reliably protected our data, such as RSA and ECC, ...

Right now, quantum computers are small and error-prone compared to where they’ll likely be in a few years. Even within those limitations, however, there have been regular claims that the hardware can ...
