Alice & Bob reports measured bit-flip lifetimes of 44 minutes on a single cat qubit and over three hours on a 12-qubit processor, which is a meaningful step for bosonic error correction. The single-qubit figure rests on 41 jump events in one 61-hour run, with a 95% confidence interval of 33 to 60 minutes, so the result is useful but not yet a general claim about scaled hardware. Readers should watch whether these lifetimes hold under active logical error correction, since that is the test that matters for fault tolerance.
Alice & Bob Demonstrates Multi-Hour Physical Bit-Flip Suppression on Single-Cat and Helium 2 Processors

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.

Superconducting hardware developer Alice & Bob has reported experimental results measuring macroscopic bit-flip lifetimes exceeding one hour on its bosonic cat-qubit hardware. Detailed in an experimental technical update titled A Cat Qubit That Jumps Every Hour, the measurements show an average idle bit-flip lifetime…
