Alice & Bob has achieved a significant breakthrough in quantum computing, demonstrating macroscopic bit-flip lifetimes exceeding one hour on their bosonic cat-qubit hardware. Their single-qubit device showed an average idle bit-flip lifetime of 44 minutes, while their 12-qubit Helium 2 processor achieved lifetimes of over three to four hours. This advancement provides crucial experimental validation for their fault-tolerant quantum computing architecture and brings them closer to realizing active logical error correction.
