Despite their immense promise to solve new kinds of problems, today’s quantum computers are inherently prone to error. A small perturbation in their surrounding ...

A new experiment uses superconducting qubits to demonstrate that quantum mechanics violates what’s called local realism by allowing two objects to behave as a single quantum system no matter how large ...

Entanglement is a form of correlation between quantum objects, such as particles at the atomic scale. The laws of classical physics cannot explain this uniquely quantum phenomenon, yet it is one of ...

A team of quantum theorists seeking to cure a basic problem with quantum annealing computers—they have to run at a relatively slow pace to operate properly—found something intriguing instead. While ...

At the end of last year, the tech giant IBM announced what might sound like a milestone in quantum computing: the first-ever chip, called the Condor, with more than 1,000 quantum bits, or qubits.

Quantum computers have been an active research topic in recent years, with several companies starting to work on specific projects. Quantum computers have some unique properties that make them truly ...

Today, Google announced a demonstration of quantum error correction on its next generation of quantum processors, Sycamore. The iteration on Sycamore isn’t dramatic ...

Superconducting qubits—bits of quantum information—have been widely considered a promising technology for moving quantum computing forward. But there's still much work to be done before they can be ...

Over the centuries, we have learned to put information into increasingly durable and useful form, from stone tablets to paper to digital media. Beginning in the 1980s, researchers began theorizing ...
