摘要：

Quantum process tomography is used to fully characterize the evolution of the quantum vibrational state of atoms. Rubidium atoms are trapped in a shallow optical lattice supporting only two vibrational states, which we characterize by reconstructing the 'c3emdash 2 density matrix. Repeating this reconstruction for a complete set of inputs allows us to completely characterize both the systems intrinsic decoherence and resonant coupling. © 2005 The American Physical Society.
