Quantum Teleportation: ‘90% Accuracy ‘Internet Milestone 27 Mile Transmission Achieved | Science | News

Experts are getting closer and closer to creating a super-secure, cutting-edge quantum Internet. Scientists have now managed to teleport quantum information over 44 kilometers.

Data fidelity (data accuracy) and transmission distance are both key components for the construction of working quantum internet – considered as the cornerstone of the next generation of communication infrastructure.

The team confirmed that they had reached a fidelity level of more than 90 percent with its quantum information.

Dr Panagiotis Spentzouris, a physicist from Caltech’s Fermilab particle physics and accelerator laboratory, said he was delighted with the success of the tests.

He said: “This is a major achievement on the way to building a technology that will define how we conduct global communications.”

Quantum Internet technology uses strange unmeasured particles suspended in a mixture of possible conditions, such as turning dice that have yet to sink.

Although rolling dice can theoretically count on any number, they are guaranteed to form a sum total, regardless of their distance from each other.

Data in one place is thus understood as immediately reflecting on another, regardless of distance.

After they have been introduced to each other, the identity is entangled in the ways in ways that are only understood once they are measured.

Ingenious arrangements that entangle three quabits can force the state of one particle to exploit the potential of another through their intertwined measure.

In the quantum universe, it is similar to the transformation of one particle into another, meaning that identity is teleported almost immediately over a distance.

However, such entanglement has yet to be determined before it is maintained, as the quibits are sent via optical fibers or even satellites around their orbit to their final destination.

And the bizarre nature of quantum information makes it very difficult to transmit entangled photons over long distances without interference.

Longer optical fiber means greater chance of noise interfering with the entangled states.

In the latest experiment, 44 km of fiber per el was channeled, setting a new record for tangled quits to successfully teleport quantum data.

But despite the fact that it has never been proven before that it works accurately over such distances, experts estimate that there are still years of work ahead before commercial applications are realized.

Dr. Spentzouris said, “With this demonstration, we are beginning to lay the groundwork for the establishment of a metropolitan quantum network in Chicago.”

Quantum entanglement and data teleportation are so complex that many experts do not fully understand how science can be used to create a quantum network.

Some believe that the technology promises almost unimaginable increases in speed and computing power.

And a quantum internet can also be very secure, which means that attempts at hacks simply destroy the lock chosen.

For now, however, experts expect that quantum networks will basically serve as specialist extensions to the current incarnation of the Internet.

What makes this study special is the accuracy and distance of teleportation of the quantum entanglement – and the everyday equipment used – that it should be relatively easy to scale this technology with hardware already available.

Professor Maria Spiropulu, a fellow physicist at Caltech, said: ‘We are very proud to have reached this milestone on sustainable, well-performing and scalable quantum teleportation systems.

“The results will be further improved with system upgrades we expect to complete by the second quarter of 2021.”
