New Approach to Quantum Error Correction
Ri Qu, Bing-jian Shang, Yan-ru Bao +1
Operator quantum error correction provides a unified framework for the known techniques of quantum error correction such as the standard error correction model, the method of decoh…
Bipartite entanglement and hypergraph states
Ri Qu, Juan Wang, Yan-ru Bao +2
We investigate some properties of multipartite entanglement of hypergraph states in purely hypergraph theoretical terms. We first introduce an approach for computing the concurrenc…
Entropic measure and hypergraph states
Ri Qu, Yi-ping Ma, Yan-ru Bao +2
We investigate some properties of the entanglement of hypergraph states in purely hypergraph theoretical terms. We first introduce an approach for computing local entropic measure…
Relationship among locally maximally entanglable states, W states and hypergraph states under local unitary transformations
Ri Qu, Yi-ping Ma, Bo Wang +1
Kruszynska and Kraus [Phys. Rev. A 79, 052304 (2009)] have recently introduced the so-called locally maximally entanglable (LME) states of n qubits which can be maximally entangled…
