Useful, error-free quantum computers could be ready in just two years, researchers at the quantum computing firm QuEra have claimed. Quantum computing is a quickly maturing technology, and the ...

Quantum computers are often benchmarked by the number of quantum bits (qubits) they have, but a large collection of unreliable qubits is no more useful than a football team of unskilled players.

Scientists have developed a new way to read the hidden states of Majorana qubits, which store information in paired quantum modes that resist noise. The results confirm their protected nature and show ...

Scientists at RIKEN have proposed a new way to make quantum systems synchronize in only one direction—like a one-way street for sound particles known as phonons. The breakthrough combines two quantum ...

Amazon AI executive Peter DeSantis told CNBC that in five-to-seven years, "we're going to start to see the first commercially useful small-scale quantum computers." DeSantis leads a new Amazon ...

A new quantum computing technology campus is on its way to Chicago’s South Side, and local K–12 students were recently given the chance to design their own versions. When completed, the Illinois ...

A quantum computer is successfully mining cryptocurrency in the first experiment of its kind, while also using a lot less energy, researchers have claimed. On Quip, the proof-of-work calculation is a ...

OAK RIDGE, Tenn. (WATE) – Oak Ridge National Laboratory is welcoming a quantum computer, that outperforms the most powerful supercomputers by using the principles of quantum mechanics. Quantum ...

Pathfinder, a 20-qubit IQM Radiance system, is now operational at the home of Frontier, the world's most powerful supercomputer for open science. It’s ORNL's first commercially procured quantum ...

YORKTOWN HEIGHTS, N. Y.—International Business Machines has spent a decade building, testing and improving in the once-theoretical realm of quantum computing at its glass-paneled laboratory complex in ...

A Chinese company has unveiled what its researchers are calling the world’s first "dual-core" quantum computer. It's a neutral-atom system designed to improve ...
