Researchers and Innovators have recently demonstrated series of successful Quantum Teleportation, which is a major breakthrough for the actualization of Quantum Internet. With the increased interest of most Governments and giant techs in quantum computing, we can agree that the quantum internet and the major breakthroughs it will bring with it is close to realization. Such breakthroughs include not just hardware such as quantum devices, but also quantum theory powered webapps. Quantum internet is different from the Classical internet in many ways, and to an extent, both will come to be used for different purposes in the future. The Quantum internet will not exterminate the traditional internet, but will come to coexist with it.

We saw the technological breakthroughs that came with the internet boom, and the various devices that were introduced for enhanced interaction between users, computers and the various web applications running on the internet. Computers, smartphones, Virtual/Augmented Reality devices, smart gadgets, modems, routers and other tools that facilitates enhanced interaction between users and the computer. Though Quantum computing would serve more of institutional needs than private, here are a list of predicted devices that would forge the usage basis of the quantum internet.

QUANTUM DEVICES THAT WILL EMERGE WITH QUANTUM TECHNOLOGY
Quantum Computers and Quantum Processors
We already know that quantum internet will run on the theory of quantum mechanics, by utilizing a network of connected quantum computers. Such sophisticated web of interconnections would not be possible without the primary tool: Quantum Computers and Quantum Processors. Quantum Computers and Quantum Processors are computing systems that function on the basis of the theory of quantum mechanics, which provides description for nature in the realm of atomic and subatomic particles, against the pattern of Classical Physics, which describes nature at an ordinary/macroscopic scale. These specialized computers/processors will store information in the form of quantum bits or qubits. Qubits, unlike the bits associated with the normal computer which stores data utilizing the Boolean Algebra in which data must be processed in an exclusive binary state or bits, will be able to store data simultaneously, utilizing the unique superimposition and entanglement characteristic of particles on the quantum level.

Quantum Routers and Modems
Like the normal internet, quantum routers will serve as networking devices that will transmit/ channel traffics in the form of data packets (Qubits) from one quantum computer/processor network to another. Quantum modems would also emerge to simplify the process of data exchange, especially when mobility is required. These two gadgets will become in-demand with time as more and more institutions adopt the quantum technology.

Quantum Repeaters
Before we look at the role of quantum repeaters in the quantum internet, let’s consider an analogous device — a non-quantum, or “classical,” repeater.

The Internet transfers information in the form of bits along fiber optic cables. Some of these cables travel long distances, such as the SEA-ME-WE 3 undersea cable that reaches from Germany to Japan. However, as light passes through these fibers, it suffers from loss, or “attenuation,” as photons are absorbed by the fiber. To account for this, a “repeater” is inserted between nodes. Repeaters simply measure the signal coming in from one side, copy it, and retransmit it at higher power to the other side. As a result, the quantum internet is able to transmit information reliably over very long distances.
