1. A quantum computing device, comprising:
a surface code lattice including/logical qubits, where/is a positive integer, the surface code lattice partitioned into two or more regions based on lattice geometry;
a compression engine coupled to each logical qubit of the/logical qubits, each compression engine configured to compress syndrome data generated by the surface code lattice using a geometry-based compression scheme; and
a decompression engine coupled to each compression engine, each decompression engine configured to:
receive compressed syndrome data;
decompress the received compressed syndrome data; and
route the decompressed syndrome data to a decoder block.
