QUANTUM COMPUTERS NEED VASTLY FEWER RESOURCES THAN THOUGHT TO BREAK VITAL ENCRYPTION

Summary from the TLDR newsletter

Two independently written whitepapers have come to the same conclusion that building a utility-scale quantum computer that can crack elliptic curves requires far fewer resources than anticipated. The papers are the latest sign that cryptographically relevant quantum computing at utility-scale is making meaningful progress. The advances are being driven by new quantum architectures that operate correctly even in the presence of errors, and ever more efficient algorithms. Neither of the papers has yet been peer reviewed.
