QGPU: Parallel logic in quantum LDPC codes

Understand

Quantum error correction is critical to the design and manufacture of scalable quantum computing systems.

• Recently, there has been growing interest in quantum low-density parity-check codes as a resource-efficient alternative to surface codes.
• Their adoption is hindered by the difficulty of compiling fault-tolerant logical operations.
• A key challenge is that logical qubits do not necessarily map to disjoint sets of physical qubits, which limits parallelism.
