Study of quantum correlations of qubits in remote cavities: biphotonic vs uniphotonic processes in each cavity

The aim of this work is to study the quantum correlations, entanglement and discord, of two qubits, each one located in its respective cavity, which interact with a common reservoir. Each qubit interacts with its own respective cavity through the emission/absorption of two correlated photons (bi-pho...

Cada qubit interactúa con su respectiva cavidad mediante la emisión/absorción de dos fotones correlacionados (bi-fotón). Inicialmente, los átomos se  consideran en un estado tipo Bell diagonal y las cavidades en estado vacío. Se calcula la evolución de las correlaciones y, para el modelo con interacciones bifotónicas sin pérdidas de fotones a través de la cavidad, se encuentra el efecto de congelamiento de las correlaciones. Cuando hay pérdidas unifotónicas o  bifotónicas hacia el reservorio se evidencia un decaimiento de las correlaciones. Se nota que los qubits se encuentran entrelazados en un lapso de tiempo  más largo cuando se considera interacciones y pérdidas bifotónicas.application/pdfspaspaUniversidad Pedagógica y Tecnológica de Colombiahttps://revistas.uptc.edu.co/index.php/ciencia_en_desarrollo/article/view/8419/10238Derechos de autor 2020 CIENCIA EN DESARROLLOhttp://purl.org/coar/access_right/c_abf2Ciencia En Desarrollo; Vol. 11 No. 1 (2020): Vol 11, Núm.1 (2020): Enero-Junio; 43-48Ciencia en Desarrollo; Vol. 11 Núm. 1 (2020): Vol 11, Núm.1 (2020): Enero-Junio; 43-482462-76580121-7488Correlaciones cuánticasBi-fotónQubitEntrelazamientoDiscordia cuánticaMecánica CuánticaQuantum correlationsBi-photonQubitEntanglementQuantum discordQuantum MechanicStudy of quantum correlations of qubits in remote cavities: biphotonic vs uniphotonic processes in each cavityEstudio de correlaciones cuánticas de qubits en cavidades remotas: procesos bifotónicos vs unifótonicos en cada cavidadinfo:eu-repo/semantics/articleTextTextohttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_2df8fbb1Gonzalez Sibaja, Francisco JavierEremeev, VitalieVillamil, Pablo001/15259oai:repositorio.uptc.edu.co:001/152592025-07-18 10:56:15.32metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co
