Precision Neuroscience raises $250M as IBM's quantum chip clears 5,000 operations
Today's stories share a common question: which technologies are moving from demonstration to something that can be built, sold and paid for?
Quantum, brain interfaces, payments and developer infrastructure each offer a different answer.
IBM's 100-qubit chip runs 5,000 operations, making its 2029 target testable
IBM has built a 100-qubit chip that can run 5,000 operations before errors overwhelm it. Qubits are the fragile units of quantum computers, and they make mistakes quickly, so the number of steps a machine can complete matters more than a raw qubit count. The reporting frames this as a depth milestone rather than a size record, and it gives DARPA's Stage C evaluation something concrete to grade. That also turns IBM's Starling roadmap, which aims for fault tolerance by 2029, into a claim that can be checked rather than just promised. Fault tolerance means a computer that catches and fixes its own errors as it works, which is what useful quantum machines will need. This rests on a single source, so treat it as a milestone to watch.
