Generalized measurement of the non-normal two-boson operator $Z_{\gamma }=a_1+\gamma a_2^{†}$

Matteo G A Paris, Giulio Landolfi, Giulio Soliani

We address the generalized measurement of the two-boson operator $Z_{\gamma }=a_1+\gamma a_2^{†}$ which, for $|\gamma {|}^2\ne 1$, is not normal and cannot be detected by a joint measurement of quadr…
