As China moves closer to building a working quantum communications network, the possibility of a quantum internet becomes more and more real. While not every quantum breakthrough elicits a positive response, in the case of a so-called quantum internet, people have a reason to be excited. In the simplest of terms, a quantum internet would be one that uses quantum signals instead of radio waves to send information. In a quantum internet, signals would be sent through a quantum network using entangled quantum particles. What does a quantum internet mean for regular internet users? As far as typical internet surfing goes, probably not much. Through what’s known as quantum encryption or quantum cryptography, people would be able to send “Unhackable” data over a quantum network.
A quantum internet could also speed up access to a working quantum computer by putting quantum computing in the cloud.
