Qubit ZooGives the canonical decoherence-free-subspace framework for quantum computation under collective decoherence, making the symmetry conditions and computational relevance explicit.
Key Results
- Formalizes the DFS condition for collective decoherence in quantum computers
- Shows how logical states can be encoded in symmetry-protected subspaces
- Connects passive DFS protection to practical quantum-information processing
