Quantum Correlations in Mixed-State Metrology

Year: 2011

Type: article

Abstract: When a quantum system is exposed to classical external noise, does the noise make it more difficult for precisions higher than the standard quantum limit to be achieved in measurements of the system's physical quantities? Researchers from Singapore and U.K. theoretically demonstrate the opposite with a set of quantum-measurement strategies that incorporate quantum discord.
