    "abstract": "Nonclassicality conditions for an oscillator-like system interacting with a\nhot thermal bath are considered. Nonclassical properties of quantum states can\nbe conserved up to a certain temperature threshold only. In this case,\naffection of the thermal noise can be compensated via transformation of an\nobservable, which tests the nonclassicality (witness function). Possibilities\nfor experimental implementations based on unbalanced homodyning are discussed.\nAt the same time, we demonstrate that the scheme based on balanced homodyning\ncannot be improved for noisy states with proposed technique and should be\napplied directly.",
