The dreaded Q-day could arrive sooner than expected, and when it does, experts say we need to be ready. Reading time 8 minutes In 1994, American mathematician Peter Shor developed a quantum algorithm ...

In 1994, mathematician Peter Shor showed that a quantum computer could factor large numbers fast enough to break the encryption used to secure most of the internet. Thirty-two years later, no one has ...

Bitcoin’s security relies on elliptic curve cryptography, a one-way mathematical function that makes deriving a private key from a public key effectively impossible for traditional computers. Shor’s ...

The quantum computing future is rapidly reshaping how scientists think about computation, with machines moving toward fault-tolerant systems capable of solving problems beyond classical limits. From ...

Quantum algorithms motivate alternative approaches to computation, and classical physical systems that generate correlations can enable parallelism. Here we present a framework for quantum-inspired ...

Building a utility-scale quantum computer that can crack one of the most vital cryptosystems—elliptic curves—doesn’t require nearly the resources anticipated just a year or two ago, two independently ...

Quantum computers of the future may be closer to reality thanks to new research from Caltech and Oratomic, a Caltech-linked start-up company. Theorists and experimentalists teamed up to develop a new ...
