A glimpse of the complex optical systems behind Quantinuum's trapped-ion quantum computers. (Quantinuum) Quantum computers ...

Physicists found a family of quantum magic states that give a computer no advantage, and an ordinary laptop can simulate them ...

There are many algorithms for which it has been mathematically proven that a quantum computer can generate results that would take a classical computer an unreasonable amount of time to generate.

Although quantum processors exist today, they are still a long way off from becoming practical replacements for classical computers. This is due to many practical considerations, not the least of ...

Quantum error correction must detect and correct errors without directly reading the quantum information. Classical ...

IBM and University of Chicago researchers have completed a quantum computation that leading classical methods could not ...

Researchers have invented a new method by which classical computers can measure the error rates of quantum machines without having to fully simulate them. Quantum ...

Recent research proves that under certain conditions, quantum annealing computers can run algorithms—including the well-known Shor's algorithm—more quickly than classical computers. In most cases, ...

Quantum computing has been hailed as a technology that can outperform classical computing in both speed and memory usage, potentially opening the way to making predictions of physical phenomena not ...

An illustration of a quantum system that was simulated by both classical and quantum computers. The highlighted sections show how the influence of the system’s components is confined to nearby ...

Despite steady improvements in quantum computers, they're still noisy and error-prone, which leads to questionable or wrong answers. Scientists predict that they won't truly outcompete today's ...

“With this Integrated Hybrid feature, you can start to use — within your quantum applications — classical code right alongside quantum code,” Krysta Svore, Microsoft’s VP of Advanced Quantum ...
