Entanglement Sudden Birth and Entanglement Sudden Death
We describe some new features and mathematical treatments of different problems of quantum optics. We focused on analytical solutions of the time-evolution operators. We show that quantum entanglement in single, two-two level or two three-level particles, allowing the coupling to be explicitly time-dependent, has some new features. We show how survivability of the quantum entanglement is determined by a specific choice of the initial state settings. In particular, we discuss the underlying conditions that may lead to the phenomena of entanglement sudden birth (delayed creation of entanglement) and sudden death (non-smooth finite-time decay).
Please note exceptional time and room.
