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 Trump administration wants a useful quantum computer in two years. Microsoft wants one in three. Independent researchers ...

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 ...

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 ...

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 ...

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 ...

A new Quantum Monte Carlo algorithm in Physical Review Letters marks a significant step forward in the quest to build ...

This article is part of a package on the future of quantum computing. Read about the quest to develop these machines here and see an illustrated field guide to qubits here. The 21st-century fervor ...
