Part 6/7:
In a demonstration in February 2020, scientists successfully sent two entangled photons over 42-kilometer loops, confirming they remained correlated upon return. This marked a significant milestone in the journey toward a quantum internet.
The Road Ahead
Despite these achievements, the quantum internet is still a long way from becoming a reality; current estimates project that a prototype may emerge within the next decade. For the average user, this will likely not replace classical internet usage for everyday activities like streaming videos. Instead, its utility will predominantly be reserved for ultra-secure communications.
