Quantum computers, devices that process information leveraging quantum mechanical effects, could tackle some tasks that are ...

Quantum hardware is starting to hit a wall that has little to do with flashy new qubit designs and everything to do with how precisely those qubits are tuned. As devices scale, tiny errors in charge ...

A Canadian quantum computing start-up claims its new qubit will enable much smaller and cheaper error-free quantum computers. But getting there will be a steep challenge. To correct its own errors, a ...

NPL, the UK's National Metrology Institute (NMI), plays a central role in providing accurate and trusted measurement across ...

Rigetti's $5.48 million project with academic partners aims to enhance qubit performance through novel chip fabrication techniques. Rigetti Computing has announced a $5.48 million grant from the Air ...

A new leap in quantum technology is changing how scientists keep qubits—quantum computing’s building blocks—ready for work. Researchers have created a tiny refrigerator that can cool qubits to lower ...

Five French startups are competing for €500M in government funding to build fault-tolerant quantum computers, with Alice & ...

Intel has launched a 12-qubit chip for quantum research. Tunnel Falls contains 12 quantum-dot qubits, and will be integrated within Intel's Quantum Software Development Kit (QSDK) and shared with ...

Rigetti Computing, Inc. (NASDAQ:RGTI) shares slid Tuesday, reflecting broader weakness in quantum technology stocks as rising Treasury yields continue to weigh on growth-oriented equities. Amid the ...

Amazon.com (NASDAQ:AMZN) Braket now offers customers access to IQM's newest quantum processing unit (QPU), Emerald. Emerald is a 54-qubit superconducting device with higher gate fidelity and full ...

Rigetti's new record was only done in an R&D setting. There are other companies with better results than Rigetti. That kind ...
