Quantum Teleportation Was Achieved Over: The year 2024 has been recorded in the history of science as the year when scientists achieved something which till now was considered possible only in science fiction. Researchers in the US have successfully teleported a quantum state through a 30-kilometer (about 18 miles) long fiber optic cable — even as waves of internet traffic flowed rapidly through the same fiber.
This achievement is far more than just a simple experiment. It not only represents a major step toward quantum computing networks, but also proves that the classical internet and quantum internet can work together in the future.

What is quantum teleportation?
Now the question arises—what exactly is quantum teleportation? Is it really like the moments depicted in science fiction films like “Star Trek,” where humans travel from one place to another in the blink of an eye?Actually, it’s not. Quantum teleportation means transferring the quantum properties of an object from one place to another. It transfers not the object itself, but its quantum state (such as energy, spin, or phase information) to another particle.When scientists do this, the first particle is destroyed, and the same property is “born” in another particle.This process is based on the principle of quantum entanglement—that is, two particles must be connected in such a way that an effect on one causes the other to react instantly.
Teleportation over a distance of 30 kilometers: An amazing feat
The researchers in this experiment, which took place in 2024, employed a 30-kilometer fiber-optic cable. This is exactly the same cable that is utilized in the provision of high-speed internet to our homes and offices. However, the problem was that on one side of the very cable there was a stream of billions of bytes of data consisting of bank transactions, video streaming, and text messaging, while on the other side of the cable scientists had to send out one photon (a small particle of light) and at the same time keep its quantum state intact.
Imagine it—it’s like protecting a thin layer of fairy floss from heavy rain. A slight carelessness, and it will melt.
How was this miracle possible?
Prem Kumar, a leading engineer at Northwestern University, and his team accomplished this feat after years of hard work.They developed techniques to control the path of photons so that they don’t collide with other signals and maintain their quantum state.
Prem Kumar explains:
“We studied where and how light scatters. Then, we positioned our photons at the point where scattering was minimal. As a result, we were able to perform quantum communication even within classical data.”
This was the first time a team had achieved quantum teleportation between real internet data streams. Previous research had been limited to simulations or within the lab.
Why is it difficult to preserve a quantum state?
The quantum world is extremely fragile.The quantum state of any particle is like a “hazy cloud of possibilities,” which can transform into reality at the slightest disturbance. This is called decoherence—the loss of quantum properties.
When a photon is sent through fiber, surrounding thermal energy, electromagnetic waves, and other data signals collide with it, destroying its quantum information.That’s why scientists believed until now that it was impossible to transmit a quantum state over such long distances without loss. But this research shattered that notion.
Quantum Internet of the Future
Now let’s talk about the future of this discovery. This experiment proved that both quantum and classical data can travel simultaneously over the same fiber network.This means we won’t need to build new, expensive quantum infrastructure.By making minor technical improvements to existing internet lines, we can create a “quantum internet”—one that will be more secure, faster, and virtually hack-proof.
Prem Kumar says:
“People used to believe that a separate network would be needed to transmit quantum particles, but if we choose the right wavelengths, quantum and classical communications can coexist within existing networks.”
Revolutionizing Security with Quantum Teleportation
The biggest advantage of this technology will be in the field of cybersecurity. Quantum teleportation allows data to be encrypted in such a way that no one can hack it in between.The moment a measurement or tampering is done on the quantum state, the system that it is operating in acknowledges it instantly and therefore it deletes the information right away. This makes it almost impossible for data to be leaked.
This technology, as a matter of fact, would be able to bring a whole new level of security to secret communications of the government, banking systems, and military networks, etc.
Combining Quantum Computing and Teleportation
Quantum teleportation is extremely useful not only for communication but also for the development of quantum computing.Quantum computers can solve problems in a few seconds that classical computers cannot solve even in hundreds of years.
Still, to build a network of quantum computing, these units should be connected, which is what teleportation technology will accomplish. It will be like a global quantum network, connecting quantum computers at different places to be able to communicate with each other and coordinate work.
A New Direction of Possibilities
This experiment might be the technological era that will be thrown to human civilization by the next wave of tech progress. With its assistance, we are able to achieve:
- An extremely secure global communication system
- Refined scientific measurement and sensing methods
- Computing networks that are faster and more efficient
- An entirely new energy and data transmission revolution
Besides, it is the next generation of the Internet that is being built through this technology, and it is a demonstration of how science and the limits of technology are really boundless.
Conclusion: The Impossible is Now Possible
The idea of ”quantum teleportation” was once only seen in movies.But today, this historic experiment in 2024 has made it a reality.Quantum teleportation of a quantum state 30 kilometers away through internet noise is a demonstration that there are no limits if we put human imagination, curiosity, and the power of science together. As Professor Prem Kumar put it –
“This project demonstrates that quantum and classical networks can be merged. This is a huge leap to the future.”Perhaps in the coming years, when you connect to the internet, this amazing technology of quantum teleportation will be at work – making it not only fast but also completely secure.
FAQs:
Q. What is quantum teleportation?
A. Quantum teleportation is the transfer of a quantum state from one particle to another over a distance without moving the particle itself.
