Local unitary equivalence of generic multi-qubits based on the CP decomposition
Jingmei Chang, Naihuan Jing
The CANDECOMP/PARAFAC (CP) decomposition is a generalization of the spectral decomposition of matrices to higher-order tensors. In this paper we use the CP decomposition to study u…

Local Unitary Invariants of Quantum States
Meiyu Cui, Jingmei Chang, Ming-Jing Zhao +2
We study the equivalence of mixed states under local unitary transformations. First we express quantum states in Bloch representation. Then based on the coefficient matrices, some…

Separability criteria based on Heisenberg-Weyl representation of density matrices
Jingmei Chang, Meiyu Cui, Tinggui Zhang +1
Separability is an important problem in theory of quantum entanglement. By using the Bloch representation of quantum states in terms of the Heisenberg-Weyl observable basis, we pre…
