Effective Hamiltonian Theory and Its Applications in Quantum Information
arXiv:0706.1090 · doi:10.1139/P07-060
Abstract
This paper presents a useful compact formula for deriving an effective Hamiltonian describing the time-averaged dynamics of detuned quantum systems. The formalism also works for ensemble-averaged dynamics of stochastic systems. To illustrate the technique we give examples involving Raman processes, Bloch-Siegert shifts and Quantum Logic Gates.
