> In the Stuttgart experiment, the quantum dots were separated only by an optical fiber of about 10 m length. "But we are working on achieving considerably greater distances," says Strobel.
> In earlier work, the team had shown that the entanglement of the quantum dot photons remains intact even after a 36-kilometer transmission through the city center of Stuttgart. Another aim is to increase the current success rate of teleportation, which currently stands at just over 70%. Fluctuations in the quantum dot still lead to slight differences in the photons.
> "We want to reduce this by advancing semiconductor fabrication techniques," says Strobel.
