A new algorithm can further exploit the twin challenges of information loss and translation to mimic a quantum computer with far fewer resources than previously ...

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

IBM and collaborators say their quantum computers outperform all known classical algorithms for three distinct tasks, but ...

Add Yahoo as a preferred source to see more of our stories on Google. Quantum computers are coming. And when they arrive, they are going to upend the way we protect sensitive data. Unlike classical ...

Computer scientists have written a network flow algorithm that computes almost as fast as is mathematically possible. This algorithm computes the maximum traffic flow with minimum transport costs for ...

Many experts believe that once quantum computers are big enough and reliable enough to solve useful problems, the most common deployment architecture will be to have them serve as accelerators for ...

Peter Shor published one of the earliest algorithms for quantum computers in 1994. Running Shor's algorithm on a hypothetical quantum computer, one could rapidly factor enormous numbers—a seemingly ...

Update: On 18 April, Yilei Chen announced an issue with his algorithm which he does not know how to fix. This means the algorithm does not undermine the mathematics behind post-quantum cryptography.

The original version of this story appeared in Quanta Magazine. Computer scientists often deal with abstract problems that are hard to comprehend, but an exciting new algorithm matters to anyone who ...
