The team demonstrated that this hybrid device enhances the collection efficiency of single photons by more than a factor of 10 compared to
a single nanocrystal without the antenna, without the need for complex and bulky optical collection systems used in many other experiments.
Using tiny nanocrystals made of semiconducting materials, the scientists developed a method in which
a single nanocrystal can be accurately positioned on top of a specially designed and carefully fabricated nano - antenna.

In the same way large antennas on rooftops direct emission of classical radio waves for cellular and satellite transmissions, the nano - antenna efficiently directed the
single photons emitted from the
nanocrystals into a well - defined direction in space.
This combined
nanocrystals - nanoantenna device was able to produce a highly directional stream of
single photons all flying to the same direction with a record low divergence angle.
