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 ...

Quantum computers promise speedups across a sweeping range of problems, from factoring large integers to simulating molecules ...

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 ...

The changing use of the word algorithm reflects this enhanced visibility. In fact, the meaning of this word has changed ...

In 1996, Dor, Halperin, and Zwick introduced an influential method that delivered a “2-approximation” in nearly optimal time. Its estimate would not exceed twice the true shortest distance. If two ...

A study describes a new computer algorithm which can be applied to Earth System Models to drastically reduce the time needed to prepare these in order to make accurate predictions of future climate ...

Researchers said it was the first time a quantum computer “posed a real and substantial threat” to encryption, but multiple limitations still hamper a full-scale hack. Chinese researchers using a ...

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 ...

One of the most well-established and disruptive uses for a future quantum computer is the ability to crack encryption. A new algorithm could significantly lower the barrier to achieving this. Despite ...

The original version of this story appeared in Quanta Magazine. One July afternoon in 2024, Ryan Williams set out to prove himself wrong. Two months had passed since he’d hit upon a startling ...

To progress in the characterization of noise for quantum computers, gate set tomography (GST) has emerged as a self-consistent protocol that accurately estimates noisy gates, state preparations, and ...
