Quantum computers can offer dramatic improvements over classical devices for data analysis tasks such as prediction and classification. However, less is known about the advantages…
Bell's Inequality, Generalized Concurrence and Entanglement in Qubits
Po-Yao Chang, Su-Kuan Chu, Chen-Te Ma
It is well known that the maximal violation of the Bell's inequality for a two-qubit system is related to the entanglement formation in terms of a concurrence. However, a generaliz…
