The Two-level Atom's Dynamics in Degenerate Multi-photon Processes

Zhang Deng

Published Jan 1, 2001• 0 citations
OpenAlex

Abstract

We study multi photon interaction of two level atom with thermal radiation field when the two level atom is put in a thermal reservoir.The atomic dynamics are analyzed.The non opposite angle elements of atoms reducible density rectangular array are gived.The time evolution properites of non opposite angle element of atoms reducible density rectangular array can reflect quantum bits decoherence when the two level atom is regarded as quantum bit in quantum computation.

Decoherence of Two-level Atoms in Thermal Radiation Field

Deng-Yu Zhang

The two-level atom is regarded as quantum-bit.We study quantum-bit reducible density rectangular array when the quantum-bit are put in a thermal reservoir.The time evolution properties of non-opposite angle element of rectangular array are obtained and decoherence of quantum-bit is analyzed.The results show the thermal radiation and quantum noise can influence the qubits' decoherence when amplitude damping be included in the consideration.

Deng-Yu Zhang

The coherence of two-level atom in a thermal radiation field without rotating wave approximation through an external controllable driving field was investigated. The time evolution properties of non-opposite angle element of two-level atom's reducible density rectangular array was discussed.

Maintaining Coherence of a Two-level Atom in Motion Through an External Controllable Driving Field

Zhang Deng

The time evolution properties of non opposite angle element of two level atoms reducible density rectangular array was discussed.Coherence properties of two level atom was studied in one photon processes when the two level atom interacts with an driving field in the thermal radiation field.When two level atoms coherence is maintained,the theoretical result demonstrates that time evolution of an external driving field is closely related to atomic jump frequency,atomic motion velocity and the average of k modul photon number etc.
