Nondeterministic noiseless amplification via non-symplectic phase space transformations
We analyse the action of an ideal noiseless linear amplifier operator, $g^{\hat {a}^{\dagger }\hat {a}}$ , using the Wigner function phase space representation. In this setting we are able to clarify the gain g for which a physical output is produced when this operator is acted upon inputs other tha...
