摘要：
A filtering algorithm which takes the measured Radon transform of the Wigner function of a quantum signal with thermal noise and produces the Wigner function of the corresponding 'clean' (noiseless) signal, is proposed. The general method is exemplified for number eigenstates with thermal noise and also for Schrodinger cats with thermal noise.
