Measuring Quantum Coherence with Entanglement.
Quantum coherence is an essential ingredient in quantum information processing and plays a central role in emergent fields such as nanoscale thermodynamics and quantum biology. However, our understanding and quantitative characterization of coherence as an operational resource are still very limited. Here we show that any degree of coherence with respect to some reference basis can be converted...
متن کاملConversion of coherence into the generalized entanglement concurrence
We investigate the k-concurrence entanglement convertability theorem of coherence. By introducing the coherence number, which is the generalization of coherence rank to mixed states, we present a necessary and sufficient condition for a coherent mixed state to be converted to an entangled state of nonzero k-concurrence. We also quantitatively compare the amount of k-concurrence entanglement wit...
متن کاملEntanglement of formation and concurrence
In both classical mechanics and quantum mechanics, one can de ne a pure state to be a state that is as completely speci ed as the theory allows. In classical mechanics a pure state might be represented by a point in phase space. In quantum mechanics it is a vector in a complex vector space. Perhaps the most remarkable feature of quantum mechanics, a feature that clearly distinguishes it from cl...
متن کاملEstimating Concurrence via Entanglement Witnesses
The interest on quantum entanglement has dramatically increased during the last two decades due to the emerging field of quantum information theory [1, 2]. It turns out that quantum entanglement may be used as basic resources in quantum information processing and communication. The prominent examples are quantum cryptography, quantum teleportation, quantum error correction codes and quantum com...
متن کاملConcurrence-based entanglement measure for Werner States
Quantum entanglement is playing very significant roles in quantum information processing such as quantum cryptography, quantum teleportation and quantum computation [1]. This motivates an increasing interest in the study of operational detection and quantification of entanglement for various quantum systems. Despite of a great deal of efforts in recent years, for the moment only partial solutio...
