A Study of the Quantum Correlations in a Tavis-Cummings System
The quantum correlations of two qubits in a microcavity with dissipation and a single quantized mode of the electromagnetic field are studied. In order to study our physical system, the Tavis-Cummings model and the formalism of the master equation of the density operator under the Born-Markov approx...

Para estudiar nuestro sistema físico, se utiliza el modelo de Tavis-Cummings y el formalismo de la ecuación maestra del operador de densidad bajo las aproximaciones de Born-Markov. El modo de cavidad estará acoplado con un láser pulsado externo y la ecuación maestra del operador de densidad que describe la evolución del sistema será resuelta numéricamente. La concurrencia, la información mutua cuántica y la discordancia cuántica se determinan para el sistema de dos qubits. Las correlaciones se estudian como una función de la cantidad adimensional τ=gt cuando la intensidad de acoplamiento cavidad láser varía, y se consideran dos condiciones iniciales en el régimen de acoplamiento débil en los que se estudió la evolución dinámica de estas correlaciones.application/pdfengspaUniversidad Pedagógica y Tecnológica de Colombiahttps://revistas.uptc.edu.co/index.php/ciencia_en_desarrollo/article/view/7232/pdfDerechos de autor 2018 CIENCIA EN DESARROLLOhttp://purl.org/coar/access_right/c_abf2Ciencia En Desarrollo; Vol. 9 No. 1 (2018): Vol 9, Núm. 1 (2018): Enero - Junio; 41-50Ciencia en Desarrollo; Vol. 9 Núm. 1 (2018): Vol 9, Núm. 1 (2018): Enero - Junio; 41-502462-76580121-7488Sistemas Cuánticos Abiertos, Ecuación Maestra, Modelo Tavis-Cummings, Correlaciones Cuánticas, Concurrencia, Información Mutua, Discordia CuánticaOpen quantum systemsmaster equationTavis-Cummings modelquantum correlationsconcurrencemutual informationquantum discord.A Study of the Quantum Correlations in a Tavis-Cummings SystemEstudio de correlaciones cuánticas en un sistema Tavis-Cumminginfo:eu-repo/semantics/articlehttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_2df8fbb1Madrid Úsuga, Duvalier001/15234oai:repositorio.uptc.edu.co:001/152342025-07-18 10:56:15.386metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co |

| description |
The quantum correlations of two qubits in a microcavity with dissipation and a single quantized mode of the electromagnetic field are studied. In order to study our physical system, the Tavis-Cummings model and the formalism of the master equation of the density operator under the Born-Markov approximations will be used. The cavity mode will be coupled with an external pulsed laser and the master equation of the density operator that describes the evolution of the system will be solved numerically. The concurrence, the quantum mutual information, and the quantum discord are determined for the system of two qubits. The correlations are studied as a function of the dimensionless quantity $\tau = gt $ when the intensity of the laser cavity coupling varies, and two initial conditions are considered in the weak coupling regime in which the dynamic evolution of these correlations was studied. |
