Quantum computing firm QuEra says it plans to make a fault-tolerant quantum computer and offer it to users through the cloud ...

This article is part of a package on the future of quantum computing. Read about the most promising applications of these machines here and see an illustrated field guide to qubits here. Inside a ...

Specialized quantum memories will be required to achieve quantum speedups for data-intensive problems. Now, a proof-of-principle demonstration of such a quantum memory has been performed with a ...

IonQ Inc. IONQ shares are up during Wednesday’s premarket session as the company was selected for DARPA’s Heterogeneous Architectures for Quantum (HARQ) program. The initiative announced on Tuesday ...

Quantum computers are already here, even though it’s not readily apparent. Now, researchers say quantum advantage—the field’s long-promised milestone of outperforming classical computers—appears to ...

Quantum computers have the potential to speed up computation, help design new medicines, break codes, and discover exotic new materials—but that's only when they are truly functional. One key thing ...

For decades, physicists have dreamed of a quantum internet: a planetary web of ultrasecure communications and super-powered computation built not from electrical signals, but from the ghostly ...

D-Wave (QBTS) keeps trying to turn quantum computing from a lab story into a real business story. That matters. Investors do ...

Quantum computers may outperform classical computers on machine learning tasks. Yet, quantum learning systems may suffer from catastrophic forgetting, which is widely believed to be an obstacle to ...

Researchers demonstrated extremely strong nonlinear light-matter coupling in a quantum circuit. Stronger coupling enables faster quantum readout and operations, ultimately improving the accuracy of ...

Atom Computing has raised over $300 million to date, including a $100 million Series C round led by Third Point Ventures and a planned $100 million from the U.S. Department of Commerce, to speed ...
