Quantum metrology gets real
Presented by Konrad Banaszek, University of Warsaw
Quantum mechanics holds the promise to enhance the performance of mesurement protocols by exploiting multiparticle superposition states of physical systems used as probes. Specific designs for quantum-enhanced schemes need to take into account noise and imperfections present in real-life implementations. This talk will review selected recent results in realistic quantum metrology, starting from interferometric estimation of a lossy phase shift and ending with general scaling laws implied by the geometry of quantum channels. In many situations, although the qualitatively improved asymptotic scaling of ideal noise-free protocols is lost, quantum mechanics can usefully offer performance beyond the standard limits.
