Increasing the storage time of quantum information in semiconductor nanostructures.

But the road to usability is arduous. Researchers at Johannes Kepler University Linz have succeeded in making progress in the storage of quantum information as part of an international collaboration. Semiconductor-based nanostructures are one thing above all: tiny. They are on the order of less than 50 nanometers. By comparison, viruses are up to 400 nanometers "big. Semiconductor structures are already used in memory cards to store classical data - but not yet in quantum computers.
