The Walking Cat Architecture
We propose a fault-tolerant quantum computer architecture for trapped-ion devices, which we call the walking cat architecture. Our blueprint includes a compiler, a detailed description of all the quantum error-correction protocols, a micro-architecture, a sufficiently fast decoder, and thorough simulations. The walking cat architecture is based entirely on low-density parity-check (LDPC) codes and relies on hardware components that have been experimentally demonstrated on small devices.
