A proposed framework for evaluating logical qubit claims has been put forth by Alice & Bob, emphasizing the need for a standardized approach to assess progress in fault-tolerant quantum computing. This five-part framework examines key aspects, including whether a logical qubit surpasses physical qubits in performance, and if it maintains stability over relevant timescales. The framework also considers the qubit's ability to improve with increased error-correction resources and operate across multiple correction cycles without relying on post-selection. By establishing a common standard, the industry can better gauge advancements in quantum computing, such as those demonstrated by Google's recent beyond-breakeven surface code experiments1. This development has significant implications for cryptographic migration, as progress in quantum computing narrows the timeline for adopting post-quantum cryptography, thereby increasing the urgency for practitioners to plan and implement quantum-resistant solutions.
