Quantum conditional mutual information and channel capacity
D. -S. Wang
Information measures acquire operational meaning through coding theorems. The quantum conditional mutual information (QCMI) is nonnegative due to strong subadditivity, yet a direct…

All about quantum error correction: distillation, mitigation, self-correction and beyond
D. -S. Wang
In this work, it is shown that many quantum error-manipulating techniques, such as distillation, error mitigation, and dynamical decoupling, are special cases of the most general f…
