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 ...

For these matrices, a decomposition into higher-dimensional invariant subspaces is desirable. In this paper we define a class of matrices where this is true, and propose a technique for calculating ...
