Quantifying precision loss in local quantum thermometry via diagonal discord
When quantum information is spread over a system through nonclassical correlation, it makes retrieving information by local measurements difficult-making global measurement necessary for optimal parameter estimation. In this paper, we consider temperature estimation of a system in a Gibbs state and...
