Quantum entanglement is a critical physical process in quantum mechanics and quantum information theory. It is a required process in quantum computing, quantum teleportation, and quantum cryptography. Entanglement detection affects the performance of quantum information processing tasks. Entanglement detection has grown in popularity over the years, and various entanglement detection methods are available, though some have application and system scale limitations. This scoping review sought to identify various measurement methods for entanglement detection in both bipartite and multipartite entanglement systems. Secondary resource indexed literatures were selected based on specific keywords from literatures published between 2017 and 2021. The goal of this study is to present a proposed conceptual framework of entanglement detection based on previous work as a guidance and reference founded on one’s specific requirements.

Quantum entanglement is a unique phenomenon of quantum mechanics that explains how two subatomic particles are correlated even if they are separated by a vast distance. The phenomena of quantum entanglement are useful resources for quantum information. In this chapter, we will study the entanglement properties of bipartite states of two electronic qubits, without observing spin-orbit interaction (SOI), produced by single-step double photoionization in helium atom following the absorption of a single photon. In absence of SOI, Russell-Saunders coupling (L-S coupling) is applicable. We observe that the entanglement depends significantly on the direction of the ejection, as well as the spin quantization of photoelectrons.

“…Debido a que el Poloxámero 407 es un polímero semicristalino compuesto por fases cristalinas de polióxido de etileno (PEO) y fases amorfas de polióxido de propileno (PPO,) en la Figura 3b se muestra el patrón de difracción de rayos X que confirma su carácter semicristalino. Los dos picos de mayor intensidad a 19° y 23° corresponden a los planos (110) y (200) de la fase cristalina del polímero [37], [38]. Los demás picos presentes de más baja intensidad se pueden atribuir a la presencia de impurezas relacionadas con algunos residuos del bloque PEO-PPO [39].…”

La impresión 3D de biomateriales es una tecnología de gran auge para la fabricación de injertos aptos para la reparación de defectos óseos con geometrías complejas. Los cementos de fosfato de calcio (CFC) son biocerámicos empleados en la medicina ortopédica debido a su similitud con la fase mineral del hueso, la capacidad para ser moldeados como una pasta y endurecer in situ. La impresión 3D de CFC potencializaría su aplicación al permitir cirugías reconstructivas de defectos con geometrías complejas, sin embargo, una limitante es la baja inyectabilidad de los CFC debido a la separación de fases que ocurre durante la inyección de la pasta. En este trabajo se ha estudiado la implementación de un polímero termosensible como el Poloxámero 407 para generar una tinta inyectable. Dicha tinta ha sido formulada para contener 5 % de hidroxiapatita carbonatada tipo B como agente nucleante biocompatible y biodegradable. Se evaluaron adiciones de soluciones acuosas de Poloxámero 407 al 0 %, 20 % y 40 % en peso como fase gel a una relación líquido/polvo de 0,75 mL/g. Se determinó el coeficiente de inyectabilidad, la cohesión de las tintas y se caracterizó la resistencia a la compresión de los cementos empleando análisis Weibull, determinado que la adición de polímero disminuye las propiedades mecánicas de los CFC en un 52,68 % y 81,23 %, respectivamente, en relación con el CFC de control (0%), atribuido a una menor densificación del cemento. Se concluyó que las adiciones del Poloxámero 407 no interfieren en la precipitación de hidroxiapatita deficiente en calcio ni en la degradación in vitro de los cementos y favorece el comportamiento de la tinta para su posible implementación en impresión 3D.
