Quantum computers struggle because their qubits are incredibly easy to disrupt, especially during calculations. A new ...

Quantum computers hold great promise for exciting applications in the future, but for now they keep presenting physicists and ...

“Our demonstration was on a two-qubit system and using a particular type of defect”, says Tim Taminiau who supervised the research. “A key challenge is to maintain and further improve the gate quality ...

Quantum computers, systems that process information leveraging quantum mechanical effects, could reliably tackle various computational problems that cannot be solved by classical computers. These ...

Technique lays the groundwork for neutral-atom quantum computers with more than 100 000 qubits, say physicists ...

Performing complex algorithms on quantum computers will eventually require access to tens of thousands of hardware qubits. For most of the technologies being developed, this creates a problem: It’s ...

Simmons says that silicon quantum processors offer an inherent advantage in scaling, too. Generating numerous registers on a ...

Quantum computers based on ions or atoms have one major advantage: The qubits themselves aren’t manufactured, and there’s no device-to-device variability among atoms. Every atom is the same and should ...

Researchers have realized a new design for a superconducting quantum processor, aiming at a potential architecture for the large-scale, durable devices the quantum revolution demands. Unlike the ...
