Peter Zoller and Ignacio Cirac proposed a trapped-ion quantum computer in which internal quantum states store qubits and a shared vibrational normal mode connects them. Carefully chosen laser pulses couple internal and motional quantum states, allowing a conditional quantum logic gate between different ions. The shared motion serves as a temporary communication channel rather than an independently addressed wire; controlling and restoring that motion is essential to the proposed gate sequence.[ref]
