Color codes are topological codes like surface codes but with a different lattice structure (triangular/hexagonal). Their key advantage is enabling transversal implementation of non-Clifford gates (like the T-gate), which surface codes cannot do. This could reduce the overhead for universal fault-tolerant quantum computing, though they have lower error thresholds.
Type
Stabilizer code (2D, topological)
Overhead
Similar to surface code but enables transversal non-Clifford gates
Threshold
~0.1-0.5% (lower than surface code)
Key Result
Enables more efficient implementation of logical T-gates
