Rigetti's technology is much faster than IonQ's, but more error-prone.

QuEra Computing (QEC) has unveiled a roadmap for advanced error-corrected quantum computers, in which it plans to achieve 100 logical error-corrected qubits in 2026. The roadmap starts this year, with ...

Quantum computing is still pre-mature and cannot live up to its hype, with unresolved errors and challenges in scalability. IonQ acknowledges the weaknesses of ...

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 ...

A new academic paper reveals a worrisome tendency for cosmic rays to disrupt quantum computer processors in a way that may be nearly impossible for current error ...

Quantum computing is a promising field with massive long-term potential, but it is still in its early commercialization phase ...

The latest machine on IBM’s quantum computing roadmap, Heron, has been given a hardware and software boost as the company pushes towards its goal of error ...

Researchers at the Amazon Web Services Inc.-led AWS Center for Quantum Computing have published what they say is their first architecture paper today, describing a theoretical blueprint for a ...

In December 2024, Google’s Willow chip became the first quantum processor to demonstrate “below threshold” error correction.

Quantum computing could take several steps forward in 2026.
