Extreme volume monogamy via bound-state engineering
Wen-Jie Zhang, Jun-Hong An
Quantum steering ellipsoid (QSE) provides a faithful representation of a two-qubit state. When extended to tripartite systems, the steerability from a trusted party to different re…

Quantum router of silicon-vacancy centers via a diamond waveguide
Wen-Jie Zhang, Xi Yan, Jun-Hong An
As a key component of quantum networks, the quantum router distributes quantum information among different quantum nodes. The silicon-vacancy (SiV) center in diamond offers a promi…

Protection of quantum steering ellipsoids in non-Markovian environments
Wen-Jie Zhang, Jun-Hong An
The quantum steering ellipsoid (QSE) provides a geometric representation, within the Bloch picture, of all possible states to which one qubit can be steered through measurements pe…
