Quantum error correction (QEC) plays a crucial role in correcting noise and paving the way for fault-tolerant quantum computing.

• This field has seen significant advancements, with new quantum error correction codes emerging regularly to address errors effectively.
• Among these, topological codes, particularly surface codes, stand out for their low error thresholds and feasibility for implementation in large-scale quantum computers.
• However, these codes are restricted to encoding a single qubit.
