X-Z Round Scheduling for the Surface Code with Defects under Biased Noise
Researchers have proposed a new scheduling method for X and Z stabilizer measurement rounds in the surface code that accounts for lattice defects and biased noise. The scheme tailors the order of stabilizer measurements to improve error correction performance under realistic noise models where certain error types are more probable.

This scheduling scheme could reduce logical error rates in surface code implementations under biased noise, making error correction more efficient and potentially lowering the qubit overhead required for fault-tolerant quantum computing.
Biased noise is prevalent in many quantum computing platforms; by adapting the schedule to the noise bias and defect structure, this method could achieve better error suppression with minimal changes to existing control software, and it could be integrated into near-term experiments.
