The U.S. Department of Energy’s Argon National Laboratory and the University of Chicago, using the quantum entanglement. Was able to set up a quantum-loop network at a distance of 83.7 km.
This means that quantum computers already have the opportunity to circulate more information than the Internet today, and to exchange data directly with each other.
Qubit instead of Bit
Quantum correlation is a physical phenomenon in which when a pair or more of small particles (photons, neutrons, or electrons) are generated and interact, the quantum states (or states) of that pair or all remain as one system. The peculiarity of these is that they remain as a single system even when the particles are separated by a large distance.
Because of the circulation of qubit processed in the Quantum Internet, it is possible to carry more data than the currently used bits (0 and 1). That is, super-quantum computers have the ability to run large applications very easily because of their high bandwidth.
Quantum Internet is a fundamentally innovative way of communicating computers, computer networks, sensors, etc. as a single system.
Why do we need a quantum internet?
Quantum Internet is not a substitute for what exists. You don’t even need a quantum internet or a quantum computer to go to Facebook and read an article in Roar. That is not to say that it will not happen one day in the future.
To support this, repeaters are also being developed in 2019 that can sometimes work even at room temperature. Their data transfer is done through fiber cables. However, Quantum Internet technology could not function without the Internet. Further research is needed to take it to the commercial level.
However, the modern benefit of this is that it has the potential to accomplish what the current Internet cannot afford. So for now, it’s just another branch of the internet. It will provide more protection to quantum data against cyber attacks and hackers, accurate GPS services, Quantum Cloud services, etc.
Imagine what would happen if a hacker had access to the normal Internet from a quantum computer. Will it be preventable that day? Perhaps, the use of Blockchain from now on will prepare us for that day.
Jumping from branch to branch with bare feet
Data travels from one place to another in the Quantum Internet very securely. Hence, it does not need to be encoded in a strange way, saying,
“This is easy to get to know to refer to the concept of quantum teleportation. Teleportation here does not mean what is in the movies, ”said Sumit Khattari, a researcher at Louisiana State University in Baton Rouge.
In quantum dichotomy, two people who want to exchange information share a pair of entangled quantum particles. Then, through a series of operations, the sender can send the required quantum information to the recipient. That’s what researcher Khattari describes.
This does not happen at the speed of light, but this method enables more accurate and secure data circulation. What makes it more special than the current encoding system, which involves complex mathematical operations, is that the data is protected by the very principles of physics.
Thought to go far but hid secretly
The only problem that stretches from telegram communications in the past to the present and quantum internet is data loss over long distances. The only solution in the world for this is to use repeaters. In March 2020, a team of Harvard and MIT researchers solved that problem.
The problem with quantum internet is that it decays when photons travel long distances. This is a huge problem for a large-scale network around the world. What a typical repeater does is take such decayed data, debug it (amplify/amplify) and send it back. But the problem so far has been that ordinary repeaters cannot be used because of the inability to capture individual photons, the perishability of quantum data, and so on.
The new researchers used the Silicon-vacancy centre Si-V. Simply put, these are the visible defects of diamonds. They are also known as colour centres. They placed colour centres and electrodes around nanoscale oval diamond openings. The photon then carries the data and interacts with it, sending it to a cold chamber where the temperature is reduced to absolute 0.
This device can store data in milliseconds, making it possible to send that data thousands of kilometres further.
In the non-eternal world, the variable quantum
In the normal world, we have the ability to somehow retain data for as long as it encodes. But the quantum world is quite different. Once the data is “produced” it begins to decay.
The other problem is the low energy content of quantum information. They are very difficult to protect from the influence of the outside world. Many quantum systems in the world currently operate in specially designed cold environments, and another alternative is the use of vacuums.
So until it is fully endowed to the world, let us applaud Neil Armstrong for this boast.
