The problem of calculating the eigensystem of a general complex matrix is well known. In many cases, however, the eigensystem is poorly determined numerically in the sense that small changes in the ...

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 a study published in Reports on Progress in Physics, research teams led by Academician GUO Guangcan and Prof. LIU Biheng from the University of Science and Technology of China (USTC) of the Chinese ...
