Evolution of Quantum States Simultaneously Undergoing Two Kinds of Quantum Noises
INTERNATIONAL JOURNAL OF THEORETICAL PHYSICS(2021)
Abstract
Using the thermal-entangled state representations, we obtain the analytical evolution of quantum states simultaneously undergoing two kinds of quantum noises that can be represented as the infinitive Kraus operator-sum representation. We also prove the normalization and trace preservation of Kraus operators. Besides, we obtain the evolutions of Wigner distribution and photon number distribution of any quantum state when simultaneously passing through two kinds of quantum noises.
