Single trapped atoms and ions offer a high level of control over their internal and external quantum state and are therefore ideal systems for implementations of quantum information processing. They also allow for the controlled emission and absorption of single photons as a resource in quantum communication and quantum networking.
We operate two independent linear Paul traps with single 40Ca+ ions, which provides a highly modular setup for implementing quantum processing and communication tools. The ions interact over 1 m distance through emission and absorption of single resonant photons. Single-photon emission in the sender ion is continuous or triggered; absorption in the receiver is signaled by a quantum jump. Frequency, polarization, and temporal shape of the single photons are controlled by appropriate laser pulses [1].
