As a rapidly expanding and cross-disciplinary subject, quantum information has attracted much attention and many leading theorists and experimentalists from physics, computer science, information, mathematics, as well as electronic engineering recently. Whereas the quantum entanglement, which can be traced back to the EPR paradox in 1935 and gave rise to the discussions on the foundations of quantum mechanics related to reality and locality, plays crucial roles in quantum information processing such as quantum computation, quantum teleportation, dense coding, quantum error correction, quantum cryptographic schemes, entanglement swapping, and remote states preparation. Many striking achievements have been witnessed for the past ten years.

The main focus of this special issue will be on the theory of quantum entanglement and its applications to quantum information processing. We invite authors to present original research articles as well as review articles that will stimulate the continuing efforts in quantum information processing, the related physics, and theory of quantum entanglement. This special issue will become an international forum for researches to summarize the most recent developments and ideas and to present new results in the field, with a special emphasis given to the theoretical aspects of the subject.

Potential topics include but not limited to:

• Quantum algorithm
• Quantum error correction and fault-tolerance
• Quantum cryptography
• Quantum teleportation
• Measure of quantum entanglement, its estimation, and evolution
• Separability criteria of quantum states, Bell-type inequalities
• Classification of quantum states under SLOCC and local unitary transformation
• Theoretical description of qubits related to cold atoms, trapped ions, quantum dots, cavity QED, Josephson junction, linear and nonlinear optics
