With classic cryptography being broken that also opens the need for quantum cryptography and commnications. China is a bit farther ahead of us on this launching their first satellite encorporating these concepts in 2020:
“The nation’s Micius satellite successfully established an ultrasecure link between two ground stations separated by more than 1,000 kilometers” source
China is launching a second newer generation satellite next year. source
Well the real world application is breaking nearly all existing encryption.
Criminals and spies are going to have a field day once it becomes practical.
The new asymmetric quantum safe algos are coming though.
