Quantum cryptography

Two research groups say they have significantly reduced the amount of qubits and time required to crack common online security technologies.

Charles Bennett and Gilles Brassard were recognized for their foundational work in quantum information science.

Henry Yuen is developing a new mathematical language to describe problems whose inputs and outputs aren’t ordinary numbers.

In theory, quantum physics can bypass the hard mathematical problems at the root of modern encryption. A new proof shows how.

Researchers got a better look at the thoughts of chatbots, amateurs learned exactly how complicated simple systems can be, and quantum computers passed an essential milestone.

Cryptography is the thread that connects Julius Caesar, World War II and quantum computing, and it now lies under nearly every part of modern life. In this week’s episode, computer scientist Boaz Barak and co-host Janna Levin discuss the past and future of secrecy.

Researchers have proved that secure quantum encryption is possible in a world without hard problems.

Artificial intelligence learned how to generate text and art better than ever before, while computer scientists developed algorithms that solved long-standing problems.

Computer scientists this year learned how to transmit perfect secrets, why transformers seem so good at everything, and how to improve on decades-old algorithms (with a little help from AI).
