This study demonstrates how integrating decoherence-free subspaces with dynamical decoupling enhances quantum state fidelity, offering a practical route to more noise-resilient quantum computing ...

Then we turn to the study of reducing subspaces of multiplication operators. It is shown that if B is a finite Blaschke product with deg B ≤ 6, then the number of minimal reducing subspaces of MB is ...
