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 ...

In this paper, we comment on the complexity of the invariant subspaces (under the bilateral Dirichlet shift f → ζ f) of the harmonic Dirichlet space D. Using the sampling theory of Seip and some work ...

The quantum Zeno effect restricts the evolution of repeatedly observed quantum systems. For a two-dimensional system the state simply is frozen in one of two eigenstates of the measurement operator ...

This is a preview. Log in through your library . Abstract Given an abelian category with arbitrary products, arbitrary co-products, and a generator, we show that the closed subspaces (in the sense of ...
