Sensitivity of entanglement measures in bipartite pure quantum states [PDF]
Modern Physics Letters B 2022; 36 (22): 2250101, 2022 Entanglement measures quantify the amount of quantum entanglement that is contained in quantum states. Typically, different entanglement measures do not have to be partially ordered. The presence of a definite partial order between two entanglement measures for all quantum states, however, allows for meaningful conceptualization of sensitivity to ...

Long-Distance Entanglement Purification for Quantum Communication. [PDF]
Physical Review Letters, 2021 High-quality long-distance entanglement is essential for both quantum communication and scalable quantum networks. Entanglement purification is to distill high-quality entanglement from low-quality entanglement in a noisy environment and it plays a key ...

Theory of Noise-Scaled Stability Bounds and Entanglement Rate Maximization in the Quantum Internet [PDF]
Sci Rep 10, 2745 (2020), 2020 Crucial problems of the quantum Internet are the derivation of stability properties of quantum repeaters and theory of entanglement rate maximization in an entangled network structure. The stability property of a quantum repeater entails that all incoming density matrices can be swapped with a target density matrix.

Entanglement in the quantum Game of Life [PDF]
Physical Review A, 2022 We investigate the quantum dynamics of a spin chain that implements a quantum analog of Conway's game of life. We solve the time-dependent Schr dinger equation starting with initial separable states and analyse the evolution of quantum correlations across the lattice.

Device-independent characterization of entanglement based on bell nonlocality
Fundamental Research, 2021 Quantum entanglement, has been acknowledged as a precious resource due to its inherent nonclassical correlations between subsystems. These quantum correlations have the potential for many quantum processes, including canonical ones: quantum cryptography,

Deterministic quantum entanglement between macroscopic ferrite samples
, 2020 We show how macroscopic magnetic samples like yttrium iron garnet samples are excellent candidates for producing deterministic quantum entanglement and, thus, providing a platform for quantum information science. This requires strong coupling with a high

Entanglement dynamics in hybrid quantum circuits [PDF]
, 2021 The central philosophy of statistical mechanics (stat-mech) and random-matrix theory of complex systems is that while individual instances are essentially intractable to simulate, the statistical properties of random ensembles obey simple universal"laws".
