Abstract: The resource theory of quantum superposition is an extension of the quantum coherent theory, in which linear independence relaxes the requirement of orthogonality. It can be used to quantify the nonclassical in superposition of finite number of optical coherent states. Based on convex roof extended, state transformation and weight, we give three methods of constructing superposition measures of quantum states, respectively. We also generalize the superposition resource theory from two perspectives.

Generalized Quantum Stein's Lemma and Second Law of Quantum Resource Theories [47.02222405817297]
A fundamental question in quantum information theory is whether an analogous second law can be formulated to characterize the convertibility of resources for quantum information processing by a single function. In 2008, a promising formulation was proposed, linking resource convertibility to the optimal performance of a variant of the quantum version of hypothesis testing. In 2023, a logical gap was found in the original proof of this lemma, casting doubt on the possibility of such a formulation of the second law.

Biorthogonal resource theory of genuine quantum superposition [0.0]
We introduce a pseudo-Hermitian representation of the density operator, wherein its diagonal elements correspond to biorthogonal extensions of Kirkwood-Dirac quasi-probabilities. This representation provides a unified framework for the inter-basis quantum superposition and basis state indistinguishability, giving rise to what we term as textitgenuine quantum superposition.

Stochastic approximate state conversion for entanglement and general quantum resource theories [41.94295877935867]
An important problem in any quantum resource theory is to determine how quantum states can be converted into each other. Very few results have been presented on the intermediate regime between probabilistic and approximate transformations. We show that these bounds imply an upper bound on the rates for various classes of states under probabilistic transformations. We also show that the deterministic version of the single copy bounds can be applied for drawing limitations on the manipulation of quantum channels.

Perturbation Theory for Quantum Information [1.2792576041526287]
We develop theories for two classes of quantum state perturbations, perturbations that preserve the vector support of the original state and perturbations that extend the support beyond the original state. We apply our perturbation theories to find simple expressions for four of the most important quantities in quantum information theory.

Hyperentanglement in structured quantum light [50.591267188664666]
Entanglement in high-dimensional quantum systems, where one or more degrees of freedom of light are involved, offers increased information capacities and enables new quantum protocols. Here, we demonstrate a functional source of high-dimensional, noise-resilient hyperentangled states encoded in time-frequency and vector-vortex structured modes. We generate highly entangled photon pairs at telecom wavelength that we characterise via two-photon interference and quantum state tomography, achieving near-unity visibilities and fidelities.

Resource theory of quantum coherence with probabilistically non-distinguishable pointers and corresponding wave-particle duality [0.6882042556551611]
We study the resource theory of quantum coherence with respect to an arbitrary set of quantum state vectors. We identify a class of measures of the quantum coherence, and in particular establish a monotonicity property of the measures. We report a relation between quantum coherence and path complementary distinguishability in a double-slit set-up.
