There’s a general consensus that performing any sort of complex algorithm on quantum hardware will have to wait for the arrival of error-corrected qubits. Individual qubits are too error-prone to be ...

British quantum engineering startup Riverlane Ltd. said today it has closed on a £15 million ($18.65 million) round of funding. The Series B round, which significantly boosts its valuation, will ...

Canadian company Nord Quantique has developed a novel method to improve quantum error correction (QEC) that will help develop smaller and energy-efficient quantum ...

Quantum computers are incredible, but they come with a big challenge: keeping errors under control. At the heart of the issue is the qubit—the quantum version of a bit. While qubits are key to quantum ...

Quantum computing is still in its infancy, easily beaten by traditional computers. One of the biggest challenges? The fact that quantum bits — qubits — are much more fragile than the bits in silicon ...

Forbes contributors publish independent expert analyses and insights. Paul-Smith Goodson is an analyst covering quantum computing and AI. Microsoft and Quantinuum quantum computing researchers just ...

The current generation of quantum hardware has been termed “NISQ”: noisy, intermediate-scale quantum processors. “Intermediate-scale” refers to a qubit count that is typically in the dozens, while ...

Researchers have made significant progress in the quest for scalable and fault-tolerant quantum computers after entangling the most logical qubits on record. When you purchase through links on our ...

In this month's look at the history of cybersecurity, David Kalat looks back at how one man's frustration at losing time led to one of the great breakthroughs in information theory. Telecommunications ...
