Fisher information as a probe of spacetime structure: relativistic quantum metrology in (A)dS

Abstract Relativistic quantum metrology studies the maximal achievable precision for estimating a physical quantity when both quantum and relativistic effects are taken into account. We study the relativistic quantum metrology of temperature in (3+1)-dimensional de Sitter and anti-de Sitter space. U...
