This article is part of a package on the future of quantum computing. Read about the most promising applications of these machines here and see an illustrated field guide to qubits here. Inside a ...

"But an exponential speedup is the most dramatic type of speed up that we expect to see from quantum computers." The key milestone for quantum computing, Lidar says, has always been to demonstrate ...

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

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 ...

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 promise of quantum computers appears to be that they will upend modern computing as we know it. With exceptional computational power, they’ll be performing feats unimaginable for any classical ...
