There are currently about 80 companies across the world manufacturing quantum computing hardware. Because I report on quantum computing, I have had a chance to watch it grow as an industry from up ...

IBM’s new experimental Loon processor attempts to address this hurdle by demonstrating that the components exist to build a fault-tolerant quantum computer at scale that can function effectively even ...

AWS's first-ever quantum chip uses "cat qubits" to reduce errors exponentially as more qubits are added to a system. Scientists say it will lead to scalable and efficient quantum computers.

IBM (IBM) announced on Wednesday that it is on a path to deliver quantum advantage by the end of next year, and fault-tolerant quantum computing by 2029. In addition, the Armonk, N.Y.-based company ...

Quantum computers are alternative computing devices that process information, leveraging quantum mechanical effects, such as ...

Forbes contributors publish independent expert analyses and insights. Paul-Smith Goodson is an analyst covering quantum computing and AI. IBM’s 300mm quantum processor wafer features multiple chips ...

Scientists have built a 98-qubit machine that they say performs better than any other quantum computer in the world. They've used it to gain new insights into superconducting physics. When you ...

A few years back, Google made waves when it claimed that some of its hardware had achieved quantum supremacy, performing operations that would be effectively impossible to simulate on a classical ...

For quantum computers to change the game of computation, scientists need to show that the machines’ calculations are correct. Now, there’s hope. Google’s Willow quantum chip has achieved verifiable ...
