Evolution of quantum correlations of two qubits in a cavity with biphotonic dissipation
In this work we study the evolution of quantum correlations in a Tavis-Cummings model that consists of two qubits and a single quantized mode of the electromagnetic field. The processes of emission / absorption of a single photon and of two correlated photons are considered for each of the qubits. T...

| description | In this work we study the evolution of quantum correlations in a Tavis-Cummings model that consists of two qubits and a single quantized mode of the electromagnetic field. The processes of emission / absorption of a single photon and of two correlated photons are considered for each of the qubits. The model is studied taking into account unifotonic and biphotonic dissipations, through a cavity that interacts with a thermal reservoir. The numerical solution of a Lindblad master equation allows us to make a description of the evolution of quantum correlations, quantum entanglement and quantum discord, as a function of time for an atomic state type superposition. It is shown that the different results of the quantum correlations present qualitatively different behaviors in their evolution. |

En este trabajo se estudia la evolución de correlaciones cuánticas en un modelo Tavis-Cummings que consta de dos qubits y un único modo cuantizado del campo electromagnético. Se consideran procesos de emisión/absorción de un sólo fotón y de dos fotones correlacionados, para cada uno de los qubits. El modelo se estudia teniendo en cuenta disipaciones unifotónicas y bifotónicas, a través de una cavidad que interactúa con un reservorio térmico. La solución numérica de una ecuación maestra Lindblad nos permite realizar una descripción de la evolución de las correlaciones cuánticas, entrelazamiento cuántico y discordia cuántica, en función del tiempo para un estado atómico tipo superposición. Se muestra que los diferentes resultados de las correlaciones cuánticas, presentan comportamientos cualitativamente diferentes en su evolución.
