- Abstract: Given a multipartite quantum system that consists of two-level particles
(qubits), one may or may not have access to all the subsystems. What can we
know about the entanglement of the multiqubit system and residual correlations
beyond two-tangle if we have access only to two-qubits at a time? Algebraic
analysis of two-qubit states yields monogamy constraints on distribution of
entanglement between sub-systems of an N-qubit state and criterion to determine
if the state has multipartite entanglement. Monogamy constraints, reported in
this letter, are relations between well known entanglement measures such as
one-tangle, two-tangles and three-tangles of an N-qubit pure state.

operations [91.3755431537592]
We extend the resource theory of entanglement for multipartite systems beyond the standard framework of local operations and classical communication.
We demonstrate that in this adjusted framework, the transformation rates between multipartite states are fundamentally dictated by the bipartite entanglement entropies of the respective quantum states.

We study Bell inequalities where measurements of different parties can have overlap.
This allows to accommodate problems in quantum information.
The scenarios considered show an interesting behaviour with respect to Hilbert space dimension, overlap, and symmetry.

Dual-unitary circuits are a class of locally-interacting quantum many-body systems.
In particular, they admit a class of solvable" initial states for which, in the thermodynamic limit, one can access the full non-equilibrium dynamics.
We show that in this case the entanglement increment during a time step is sub-maximal for finite times, however, it approaches the maximal value in the infinite-time limit.

We consider the kinematics of bi-partite quantum states as determined by observable quantities.
There is a remarkable connection between the presence of non-classical correlations and the chirality of the two bases generated by the singular value decomposition of the correlation matrix of the Bloch vectors.

We propose ProxConnect (PC) as a generalization of BinaryConnect (BC) and we prove its convergence properties.

We show that different reference frame perspectives induce different sets of subsystem observable algebras, which leads to a gauge-invariant, frame-dependent notion of subsystems and entanglement.
Such a QRF perspective does not inherit the distinction between subsystems in terms of the corresponding tensor factorizability of the kinematical Hilbert space and observable algebra.
Since the condition for this to occur is contingent on the choice of QRF, the notion of subsystem locality is frame-dependent.

Entanglement of high-dimensional and multipartite quantum systems offer promising perspectives in quantum information processing.
We consider the overlaps between the maximal quantum mean values and the classical bound of the CHSH inequalities for pairwise-qubit states in two-dimensional subspaces.
We show that the concurrence of a pure state in any high-dimensional multipartite system can be equivalently represented by these overlaps.

A basis-invariant measure of coherence known as the intrinsic degree of coherence has been established for classical and single-particle quantum states.
We show that the intrinsic degree of coherence of a two-qubit state puts an upper bound on the violations of Bell inequalities.
We show that the range of values that the concurrence of a two-qubit state can take is decided by the intrinsic degree of coherence of the two-qubit state.
