Quantum teleportation: "90 percent accuracy" internet milestone 27 mile transfer achieved

TELEPORTATION has now been attained over a record distance, bringing the next-generation internet one step closer, researchers have revealed.

Experts are edging ever-closer to creating a super-secure, cutting-edge quantum internet. Scientists have now managed to teleport quantum information over 27 miles (44km).

Data fidelity (data accuracy) and transfer distance are both key components for constructing working quantum internet – considered the cornerstone next-gen communications infrastructure.

The team has confirmed it has achieved a greater-than 90 percent fidelity level with its quantum information.

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

He said: ”This is a key achievement on the way to building a technology that will redefine how we conduct global communication.”

Quantum internet technology uses strange unmeasured particles suspended in a mix of possible states, much like spinning dice yet to settle.

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

Data in one location is therefore understood as instantly reflecting that in another, irrespective of how distance.

Once introduced to one another, qubits have their identities ‘entangled’ in ways only understood once they are measured.

Ingenious arrangements entangling three qubits can force the state of one particle to adopt the potentiality of another through their mutually-entangled partner.

In the quantum universe, this is similar to transforming one particle into another, meaning identity is almost-instantly teleported across a distance.

However, such entanglement still requires to be first established, before being maintained as the qubits are sent to their eventual destination via optical fibres or even orbiting satellites.

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

Longer fibre optics mean increased opportunity for noise to interfere with the entangled states.
