The first complete, end-to-end fault-tolerant resource estimate for running Shor’s algorithm—the team used IonQ’s Walking Cat architecture to demonstrate how a specific application can be optimized for a trapped-ion quantum computer. This work concludes that a 20,000-physical-qubit IonQ quantum computer, once developed, is expected to be able to break secp256k1, the 256-bit elliptic curve used by blockchain technology such as Bitcoin, in just under 26 days. This architectural and resource-estimation study is consistent with IonQ's publicly stated roadmap, which targets systems with the relevant capabilities in the 2028 timeframe.
