(Tony Melov/Canva) Quantum mechanics is so odd that even the visionary genius who described the secrets of the Universe ...

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 ...

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 ...

Qubits -- the fundamental units of quantum information -- drive entire tech sectors. Among them, superconducting qubits could be instrumental in building a large-scale quantum computer, but they rely ...

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.

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 ...

To get quantum computing to work, we will ultimately need lots of high-quality qubits, which we can tie together into groups of error-corrected logical qubits. Companies are taking distinct approaches ...

A qubit is the delicate, information-processing heart of a quantum device. In the coming decades, advances in quantum information are expected to give us computers with new, powerful capabilities and ...
