Quantum

Quantum Error Correction Threshold Calculator

Estimate the logical error rate of surface, Steane, or generic quantum error-correcting codes given physical error rate, code distance, and decoder choice. Use this when evaluating whether a quantum device is below the fault-tolerance threshold.
