Abstract

In the development of thermodynamics Maxwell's demon plays an important role in discussing the second law of thermodynamics Also Szilard engine is one of the widely discussed thought experiment for Maxwell's demon This model helps us to find the relation between the entropy decrease and information ow in detection process Besides heat and work transfer in processes in Szilard engine could be clarified But there is a problem in a quantum Szilard engine: Assuming the initial state in Szilard engine is not the thermalized state but the entangled state What's the difference between those thermal processes? In this thesis I will investigate the quantum version of the Szilard engine and consider several cases of two-particle entangled initial states with different information flow In the model of infinite quantum well I will show that there is no relation between the absorbed heat and information ow However the second law of thermodynamics still holds I'll also use some special initial states to analyze the identical particle effect which mimics the bosonic and fermionic properties of the quantum states in the quantum Szilard engine
