SLOCC and LU classification of black holes with eight electric and magnetic charges
Dafa Li, Maggie Cheng, Xiangrong Li +1
In \cite{Linde}, Kallosh and Linde discussed the SLOCC classification of black holes. However, the criteria for the SLOCC classification of black holes have not been given. In addi…
A relation among tangle, 3-tangle, and von Neumann entropy of entanglement for three qubits
Dafa Li, Maggie Cheng, Xiangrong Li +1
In this paper, we derive a general formula of the tangle for pure states of three qubits, and present three explicit local unitary (LU) polynomial invariants. Our result goes beyon…
Polynomial invariants of degree 4 for even- qubits and their applications in entanglement classification
Xiangrong Li, Dafa Li
We develop a simple method for constructing polynomial invariants of degree 4 for even- qubits and give explicit expressions for these polynomial invariants. We demonstrate the…
Method for classifying multiqubit states via the rank of the coefficient matrix and its application to four-qubit states
Xiangrong Li, Dafa Li
We construct coefficient matrices of size 2^l by 2^{n-l} associated with pure n-qubit states and prove the invariance of the ranks of the coefficient matrices under stochastic loca…
Rank-based SLOCC classification for odd n qubits
Xiangrong Li, Dafa Li
We study the entanglement classification under stochastic local operations and classical communication (SLOCC) for odd n-qubit pure states. For this purpose, we introduce the rank…
Classification of general n-qubit states under stochastic local operations and classical communication in terms of the rank of coefficient matrix
Xiangrong Li, Dafa Li
We solve the entanglement classification under stochastic local operations and classical communication (SLOCC) for general n-qubit states. For two arbitrary pure n-qubit states con…
