Phys. Rev. A 72, 013615 (2005) [5 pages]Quantum process tomography on vibrational states of atoms in an optical latticeReceived 4 April 2005; published 25 July 2005 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 2×2 density matrix. Repeating this reconstruction for a complete set of inputs allows us to completely characterize both the system’s intrinsic decoherence and resonant coupling. © 2005 The American Physical Society URL:
