    Robustness of coherence: an operational and observable measure of quantum coherence

    Robustness of coherence: an operational and observable measure of quantum coherence by Napoli, Carmine, Bromley, Thomas R., Cianciaruso, Marco, Piani, Marco, Johnston, Nathaniel, Adesso, Gerardo

    Published 2016
    “…Quantifying coherence is an essential endeavour for both quantum foundations and quantum technologies. Here the robustness of coherence is defined and proven a full monotone in the context of the recently introduced resource theories of quantum coherence. …”

    There is more to quantum interferometry than entanglement

    There is more to quantum interferometry than entanglement by Bromley, Thomas R., Silva, Isabela A., Oncebay-Segura, Charlie O., Soares-Pinto, Diogo O., deAzevedo, Eduardo R., Tufarelli, Tommaso, Adesso, Gerardo

    Published 2017
    “…Entanglement has long stood as one of the characteristic features of quantum mechanics, yet recent developments have emphasized the importance of quantumness beyond entanglement for quantum foundations and technologies. We demonstrate that entanglement cannot entirely capture the worst-case sensitivity in quantum interferometry when quantum probes are used to estimate the phase imprinted by a Hamiltonian, with fixed energy levels but variable eigenbasis, acting on one arm of an interferometer. …”
