Phase-Controlled Collapse and Revival of Entanglement of Two Interacting Qubits
Vladimir S. Malinovsky, Ignacio R. Solá · Physical Review Letters · 2006
We demonstrate the strong dependence of the entanglement dynamics of two distinguishable qubits in a trap on the relative phase of the pulses used for excitation. We show that the population and entanglement exhibits collapses and full revivals when the initial distribution of phonons is a coherent state.
