Abstract:   (1003 Views)

In this article, we study the quantum Fisher information for decoherence parameter in an interferometer. It is shown that with increasing decoherence, the quantum Fisher information is reduced, and hence the process of parameter estimation becomes more inaccurate. We also show when the travelling particles encounter the first and second beam splitter, the quantum Fisher information does not change.

Keywords: quantum measurement, quantum Fisher information, density matrix, decoherence
