Covariance matrices under Bell-like detections
Gaetana Spedalieri, Carlo Ottaviani, Stefano Pirandola
We derive a simple formula for the transformation of an arbitrary covariance matrix of (n+2) bosonic modes under general Bell-like detections, where the last two modes are combined…
Quantum reading under a local energy constraint
Gaetana Spedalieri, Cosmo Lupo, Stefano Mancini +2
Nonclassical states of light play a central role in many quantum information protocols. Their quantum features have been exploited to improve the readout of information from digita…
A limit formula for the quantum fidelity
Gaetana Spedalieri, Christian Weedbrook, Stefano Pirandola
Quantum fidelity is a central tool in quantum information, quantifying how much two quantum states are similar. Here we propose a limit formula for the quantum fidelity between a m…
