Inertia of two-qutrit entanglement witnesses
Changchun Feng, Lin Chen, Chang Xu +1
Entanglement witnesses (EWs) are a fundamental tool for the detection of entanglement. We investigate the inertias of bipartite EWs constructed by the partial transpose of NPT stat…

Faster quantum computation with permutations and resonant couplings
Yingkai Ouyang, Yi Shen, Lin Chen
Recently, there has been increasing interest in designing schemes for quantum computations that are robust against errors. Although considerable research has been devoted to develo…
