## Core Methodology

### Key Concepts
High-rate quantum low-density parity-check (qLDPC) codes are a leading candidate for fault-tolerant quantum computing. They feature higher encoding rates than planar alternatives such as the surface code, but their implementation often entails significant hardware hurdles like the need for long-range couplers. Demonstrated nine quantum error-correcting codes with starkly different qubit connectivity requirements on a single trapped-ion device without hardware reconfiguration. Achieved breakeven
