  We present the experimental realization of a quantum fiber-pigtail. The
device consists of a semiconductor quantum-dot embedded into a conical photonic
wire that is directly connected to the core of a fiber-pigtail. We demonstrate
a photon collection efficiency at the output of the fiber of 5.8% and suggest
realistic improvements for the implementation of a useful device in the context
of quantum information. We finally discuss potential applications in scanning
probe microscopy.
