A personal laptop running open-source software has matched the outputs of D-Wave Systems' 5,000-qubit Advantage2 quantum annealer on a class of quantum dynamics problems the company stated in March ...

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 ...

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 ...

Quantum computing advances are accelerating as various players address issues like cooling and control. Classical computers can’t do everything, which is why quantum computers exist in the first place ...

Shares of IonQ advanced after the company said it was deploying its Superion 256 quantum computer at the Nvidia Accelerated Quantum Research Center. Shares were up 4.9% at $42.73 as of midday ...

A team of scientists has devised means for classical computing to mimic a quantum computing with far fewer resources than previously thought. The scientists' results show that classical computing can ...

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 ...

Quantum computers hold great promise for applications from drug discovery to cybersecurity. Yet figuring out what would give quantum computers their edge over everyday "classical" computers is a ...

“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 ...

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 ...

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 ...
