Quanutm-State Texture as a Resource: Measures and Nonclassical Interdependencies

Abstract: Quantum-state texture is a newly recognized quantum resource that has garnered attention with the advancement of quantum theory. In this work, we discuss several main tasks concerning quantum-state texture resource theory, including quantum-state texture measure, quantum state transformation under free operations, and relations between quantum resources. We first provide two new quantum-state texture measures and propose specific form of function for constructing quantum-state texture measures through a convex roof method. Then, we present the maximal probability of quantum state transformation through free operations. Lastly, we establish relationships between quantum-state texture and other highly regarded quantum resources, such as coherence, imaginary, and predictability. Our research complements the measure theory of quantum-state texture and enriches the theory framework of quantum-state texture resource.
