Among several qubit technologies, spin qubits are a promising candidate for large-scale QC, since (1) they have a small footprint allowing them to be densely integrated and (2) they can operate at relatively high temperatures (>1K) [1], potentially reducing system cost and complexity. Executing practical quantum algorithms with real-time quantum error correction will
