Title: Orthogonal Polynomials on the Unit Circle, Mutually Unbiased Bases, and Balanced States
Authors: Graeme Reinhart, Brian Simanek,
Abstract summary: Two interesting phenomena for the construction of quantum states are that of mutually unbiased bases and that of balanced states. In the case of mutually unbiased bases, we show that this approach does not produce such bases. In the case of balanced states, we provide examples of pairs of orthonormal bases and states that are balanced with respect to them.

Abstract: Two interesting phenomena for the construction of quantum states are that of mutually unbiased bases and that of balanced states. We explore a constructive approach to each phenomenon that involves orthogonal polynomials on the unit circle. In the case of mutually unbiased bases, we show that this approach does not produce such bases. In the case of balanced states, we provide examples of pairs of orthonormal bases and states that are balanced with respect to them. We also consider extensions of these ideas to the infinite dimensional setting.

Non-equilibrium dynamics of charged dual-unitary circuits [44.99833362998488]
interplay between symmetries and entanglement in out-of-equilibrium quantum systems is currently at the centre of an intense multidisciplinary research effort. We show that one can introduce a class of solvable states, which extends that of generic dual unitary circuits. In contrast to the known class of solvable states, which relax to the infinite temperature state, these states relax to a family of non-trivial generalised Gibbs ensembles.

Geometry of degenerate quantum states, configurations of $m$-planes and invariants on complex Grassmannians [55.2480439325792]
We show how to reduce the geometry of degenerate states to the non-abelian connection $A$. We find independent invariants associated with each triple of subspaces. Some of them generalize the Berry-Pancharatnam phase, and some do not have analogues for 1-dimensional subspaces.

Coherent loop states and angular momentum [0.0]
We study Bohr-Sommerfeld states in the context of the irreducible representations of SU(2). We show that they recover the usual basis of angular momentum eigenstates used in physics. As an application, we use these states to derive Littlejohn and Yu's geometric formula for thes of the Wigner matrix elements.

Orthonormal bases of extreme quantumness [1.1510009152620668]
Some coherent and anticoherent spin states are known as optimal quantum rotosensors. We introduce a measure of quantumness for orthonormal bases of spin states, determined by the average anticoherence of individual vectors and the Wehrl entropy.

Simulating Entanglement beyond Quantum Steering [15.808504285017948]
We quantify the resource content of such states in terms of how much shared randomness is needed to simulate their behavior. We rigorously show that the shared randomness cost is unbounded even for some two-qubit unsteerable states.

A triality pattern in entanglement theory [0.0]
We present new connections between three types of quantum states: positive under partial transpose states, symmetric with positive coefficients states and invariant under realignment states. These connections add new evidence to the pattern that for every proven result for one of these types, there are counterparts for the other two, which is a potential source of information for entanglement theory.
