AITwo independent research efforts used the same AI system to reach closely aligned proofs for a longstanding quantum cryptography problem, highlighting both a technical advance and a changing model of scientific discovery.

ScienceRecent demonstrations in protein chemistry and quantum materials suggest that quantum processors are beginning to contribute to scientific workflows, but as specialised partners to classical computing rather than standalone replacements.
