A many-particle system may exhibit non-local behavior in that measurements performed on one of the particles can affect a second particle that is far apart. These so-called entangled states are essential for the implementation of quantum information protocols and gates for quantum computation. Here, we use ultrafast optical pulses and coherent techniques to create spin entangled states of non-interacting electrons bound to donors in a CdTe quantum well.A many-particle system may exhibit non-local behavior in that measurements performed on one of the particles can affect a second particle that is far apart.
