Toward a 2D Local Implementation of Quantum LDPC Codes
Toward a 2D Local Implementation of Quantum LDPC Codes
Geometric locality is an important theoretical and practical factor for quantum low-density parity-check (qLDPC) codes which affects code performance and ease of physical realization. For device architectures restricted to 2D local gates, naively implementing the high-rate codes suitable for low-overhead fault-tolerant quantum computing incurs prohibitive overhead. In this work, we …
