The design of error suppression mechanisms and associated fault-
tolerance architectures is at the heart of quantum computation:
Maintaining coherence is paramount if the goal is to realize a quantum
advantage over classical information-processing. The theory of quantum
error correction has recently seen significant developments with e.g., the
discovery of good quantum low-density parity check codes. However,
translating these theoretical advancements into practice necessitates
addressing experimental constraints associated with current and future
computational architectures. We discuss the particular challenges arising
from the fact that available operations are typically local, acting only on
adjacent qubits. This involves characterizing the potential of local
operations for computation and the design of schemes for fault-tolerant
quantum information-processing based on such operations.
