IBM announced that it will provide cloud access to a dual‑processor quantum system built from two 520‑qubit chips. The company plans to link the chips before the end of 2026 and open the service to customers in 2027. …

The move marks the first time a major vendor has offered a multi‑chip quantum machine as a service. IBM’s own roadmap has long spoken of scaling beyond 1,000 qubits, but the dual‑processor approach is a concrete step …

The crypto community has been watching IBM’s scaling plans because each added qubit chips away at the safety margin of current public‑key schemes. Recent research from Google and Oratomic shows that the number of logi…

If IBM delivers a 1,040‑qubit system that can be programmed as a single logical space, the gap between theory and practice shrinks dramatically. Even if error‑correction still costs a factor of ten, the effective logi…
