| Abstract: | 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. | |
