• Abstract summary: We establish the correspondence of two dimensional paraxial and three dimensional non-paraxial optical beams with the qubit and qutrit systems respectively. For pure two qubit and qutrit systems, it quantifies the global entanglement and reduces the complementarity relation to the triality relation between coherence, predictability and entanglement.

• Abstract: Establishing the correspondence of two dimensional paraxial and three dimensional non-paraxial optical beams with the qubit and qutrit systems respectively, we derive a complementary relation between Hilbert-Schmidt coherence, generalized predictability and linear entropy. The linear entropy, a measure of mixedness is shown to saturate the complementarity relation for mixed bi-partite states. For pure two qubit and qutrit systems, it quantifies the global entanglement and reduces the complementarity relation to the triality relation between coherence, predictability and entanglement. We analyze these relations in wedge-product formalism in order to investigate the innate geometry of the complex vector space. The derived complementary relations offer insights into our ability to manipulate and utilize quantum properties for practical advancements.

• Exploring entanglement in finite-size quantum systems with degenerate ground state [0.0]
  We develop an approach for characterizing non-local quantum correlations in spin systems with exactly or nearly degenerate ground states. We generate a finite set of their random linear combinations with Haar measure, which guarantees that these combinations are uniformly distributed in the space spanned by the initial eigenstates. We elaborate on the problem of estimating observables on the basis of the single-shot measurements of numerous degenerate eigenstates.

• Multipartite Optimized Correlation Measures and Holography [8.594140167290098]
  We focus on optimized correlation measures, linear combinations of entropies minimized over all possible purifications of a state that satisfy monotonicity conditions. We present a procedure to derive such quantities, and construct a menagerie of symmetric optimized correlation measures on three parties. Some correlation measures vanish only on product states, and thus quantify both classical and quantum correlations. We then use a procedure motivated by the surface-state correspondence to construct holographic duals for the correlation measures as linear combinations of bulk surfaces.
