For the first time, physicists have performed machine learning on a photonic quantum computer, demonstrating that quantum computers may be able to exponentially speed up the rate at which certain machine learning tasks are performed—in some cases, reducing the time from hundreds of thousands of years to mere seconds. The new method takes advantage of quantum entanglement, in which two or more objects are so strongly related that paradoxical effects often arise since a measurement on one object instantaneously affects the other. Here, quantum entanglement provides a very fast way to classify vectors into one of two categories, a task that is at the core of machine learning.

At this stage, it's difficult to see the technology being used in normal computers, because of its need for sub-zero temperatures and powerful magnets. However, it could be very useful in research institutions.

But how could this quantum internet be built anytime soon when we currently can only build very limited quantum computers? Well, the devices in the quantum internet don’t have to be completely quantum in nature, and the network won’t require massive quantum machines to handle the communication protocols.

Future devices wouldn’t need to be full quantum computers to connect to the quantum internet.
One qubit here and there is all a quantum communication network needs to function. Instead of replacing the current infrastructure of optical fibres, data centres and base stations, the quantum internet will build on top of and make maximum use of the existing, classical internet.

With such rapid progress being made, quantum internet technology is set to shape the business plans of telecom companies in the near future. Financial institutions are already using quantum communication networks to make inter-bank transactions safer. And quantum communication satellites are up and running as the first step to extending these networks to a global scale.

The pipes of the quantum internet are effectively being laid as you read this. When a big quantum computer is finally built, it can be plugged into this network and accessed on the cloud, with all the privacy guarantees of quantum cryptography.
