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 ...

Quantum computers promise enormous computational power, but the nature of quantum states makes computation and data inherently "noisy." Rice University computer scientists have developed algorithms ...

There are many algorithms for which it has been mathematically proven that a quantum computer can generate results that would ...

"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 ...

Researchers from the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, Northeastern University, Google Quantum AI, and the University of Texas at Austin have developed a new quantum ...

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 ...

A gold superconducting quantum computer hangs against a black background. Quantum computers, like the one shown here, could someday allow chemists to solve problems that classical computers can’t.

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 ...
