• Abstract: Nonlocal quantum correlations among the quantum subsystems play essential roles in quantum science. The violation of the Svetlichny inequality provides sufficient conditions of genuine tripartite nonlocality. We provide tight upper bounds on the maximal quantum value of the Svetlichny operators under local filtering operations, and present a qualitative analytical analysis on the hidden genuine nonlocality for three-qubit systems. We investigate in detail two classes of three-qubit states whose hidden genuine nonlocalities can be revealed by local filtering.

• Locally inaccessible hidden quantum correlations [0.0]
  We prove, modulo a conjecture on quantum steering ellipsoids being true, the existence of the phenomenon of locally inaccessible hidden quantum correlations. We show examples of two-qubit states with locally inaccessible hidden quantum correlations and, furthermore, two-qubit states with locally inaccessible maximal hidden quantum correlations.

• Local Purity Distillation in Quantum Systems: Exploring the Complementarity Between Purity and Entanglement [41.94295877935867]
  We introduce and develop the framework of Gibbs-preserving local operations and classical communication. We focus on systems with fully degenerate local Hamiltonians, where local cooling aligns with the extraction of local purity. Our findings open doors to various practical applications, including techniques for entanglement detection and estimation.

• Tight upper bound of genuine four party Svetlichny type nonlocality with and without local filtering [0.0]
  identifying the nonlocality of a multiparty quantum state is an important task in quantum mechanics. Here we have developed a tight upper bound for genuine four party Svetlichny type nonlocality. The relations between the genuine multipartite entanglement and the maximal quantum value of the Seevinck and Svetlichny operators for pure four qubit states are also discussed.

  We show that processes in local effective theories can be spoofed with a quantum system with fewer degrees of freedom. We highlight how approximate overlapping qubits are conceptually connected to Hilbert space dimension verification, degree-of-freedom counting in black holes and holography.

• Entanglement and localization in long-range quadratic Lindbladians [49.1574468325115]
  Signatures of localization have been observed in condensed matter and cold atomic systems. We propose a model of one-dimensional chain of non-interacting, spinless fermions coupled to a local ensemble of baths. We show that the steady state of the system undergoes a localization entanglement phase transition by tuning $p$ which remains stable in the presence of coherent hopping.

• Revealing hidden standard tripartite nonlocality by local filtering [0.0]
  Quantum nonlocality is a significant quantum correlation that is stronger than quantum entanglement and EPR steering. We show that the hidden standard nonlocality can be revealed by local filtering which can enhance the robustness of the noised entangled states.

  We show that the phenomenon of more nonlocality with less entanglement can be observed for two qubits, while still being at the single-copy level. The results are potentially useful for secure quantum communication technologies with an optimal amount of resources.

We furthermore show that there actually exists a trade-off between the amount of quantum correlations which can be extracted and the filtering probability with which such protocol can be implemented.
