Local Quantum Uncertainty and Quantum Interferometric Power in an Anisotropic Two-Qubit System

چکیده

Investigating the favorable configurations for non-classical correlations preservation has remained a hotly debated topic last decade. In this regard, we present two-qubit Heisenberg spin chain system exposed to time-dependent external magnetic field. The impact of various crucial parameters, such as initial strength and angular frequency field along with state’s purity anisotropy spin-spin on dynamical behavior quantum are considered. We utilize local uncertainty (LQU) interferometric power (QIP) investigate dynamics correlations. show that under critical anisotropy, in can be successfully preserved. LQU QIP suffer drop interaction between is initiated, however, quickly regained by system. This tendency confirmed computing measure according Clauser–Horne–Shimony–Holt inequality. Notably, final preserved levels only varied when variation caused purity.

Dominant Strategies in Two Qubit Quantum Computations

Viewing two qubit quantum computations as two player “quantum” games, initial states are characterized that play the role of dominant strategies in the corresponding game model and give rise to Nash equilibrium outcomes. Nash equilibrium outcomes are optimal under given constraints and therefore offer a game-theoretic measure of constrained optimization of two qubit quantum computations.

Completely positive covariant two-qubit quantum processes and optimal quantum NOT operations for entangled qubit pairs

The structure of all completely positive quantum operations is investigated which transform pure two-qubit input states of a given degree of entanglement in a covariant way. Special cases thereof are quantum NOT operations which transform entangled pure two-qubit input states of a given degree of entanglement into orthogonal states in an optimal way. Based on our general analysis all covariant ...

Quantum correlating power of local quantum channels

We define quantum-correlating power (QCP) of a local quantum channel acting on the left part of a bipartite quantum system as the maximum amount of left quantum correlation that can be created by this channel. We prove that for any local channel, the optimal input state, which corresponds to the maximum quantum correlation in the output state, must be a classical-classical state. Further, the s...
