Quantifying High-Order Interdependencies in Entangled Quantum States [43.70611649100949]
We introduce the Q-information: an information-theoretic measure capable of distinguishing quantum states dominated by synergy or redundancy. We show that quantum systems need at least four variables to exhibit high-order properties. Overall, the Q-information sheds light on novel aspects of the internal organisation of quantum systems and their time evolution.

A note on Majorana representation of quantum states [0.0]
For any $d > 1$ there is a one-one correspondence between a quantum state of dimension $d$ and $d-1$ qubits represented as $d-1$ points in the Bloch sphere. We present a simple scheme for constructing $d-1$ points on the Bloch sphere and the corresponding $d-1$ qubits representing a $d$-dimensional quantum state.

Berry phases of higher spins due to internal geometry of Majorana constellation and relation to quantum entanglement [0.0]
Majorana stars provide a geometric understanding of the structures of general quantum states. Berry phase of a spin-1/2 is given by half the solid angle enclosed by the close path of its Majorana star. If the spin-1 state is taken as a symmetrized two-qubit state, the extra contribution to the Berry phase is given by the self-rotation of the Majorana constellation.
