演題:Error bounds on the universal Lindblad equation in thermodynamic limit
要旨:
Open quantum many-body systems have attracted much attention recently. Quantum control using dissipation and noisy quantum computing are examples of such systems. Although the Lindblad equation is widely used to describe Markovian dynamics of open quantum systems, its microscopic derivation has not been established yet. Therefore, many derivations of the Lindblad equation have been proposed so far. Universal Lindblad Equation (ULE) is superior among them since ULE is applicable to many-body systems. However, there has been a problem that the accumulation of errors had not been analytically evaluated when ULE was applied to many-body systems. In our research, we analytically evaluated the accumulation of errors in thermodynamic limit and obtained a finite error independent of both time and system size.
In this talk, I will start with the basic concepts of open quantum systems and introduce studies on the derivation of the Lindblad equation including our result.
