...For this matrix S, we know closed formulas only for specific types of two-mode Gaussian states [768] which appear in problems of quantum sensing [601], such as quantum illumination [603] and quantum reading [604]....

...A fundamental protocol which is closely related to quantum metrology is quantum channel discrimination (Acin, 2001; Childs et al., 2000; Invernizzi et al., 2011; Lloyd, 2008; Pirandola, 2011; Sacchi, 2005; Tan et al., 2008), which may be seen as a sort of digitalized version of quantum metrology....

...Nevertheless the scheme assures a superior performance with respect to the use of coherent states; in particular, an increase by a factor 4 of the exponent −(lnP (e))/M of the asymptotic error probability P (e) (where M is the number of transmissions) (Tan et al., 2008)....

...One which is very well known is quantum illumination (Lloyd, 2008; Tan et al., 2008) which forms the basis for a “quantum radar” (Barzanjeh et al., 2015)....
