In an innovative achievement to make quantum computing a large -scale practice, scientists from the University of Oxford have successfully demonstrated quantum computing distributed for the first time. By allowing small quantum devices to work together instead of overloading a single machine, the researchers achieved quantum teleportation of logical doors, according to the findings published in the magazine NatureIn a study entitled ‘Quantum computing distributed through an optical network link’.
Quantum computers use qubits (quantum bits) instead of traditional bits of classic computers that can perform calculations at unattainable speeds by current technology. However, the scalability of quantum computing has remained a challenge for scientists, although technology is presented for years.
To overcome the obstacle, the researchers, instead of moving the qubits to achieve quantum teleportation, used quantum teleportation of logical doors (the minimum components of an algorithm) in a network link.
“The previous demonstrations of quantum teleportation have focused on the transfer of quantum states between physically separate systems. In our study, we use quantum teleportation to create interactions between these distant systems,” said Dougal Main studio.
“This advance allows us to” effectively wire different quantum processors in a single quantum computer fully connected, “he added.
Directed by Professor David Lucas, the research team managed to teleport the quantum state of an ion (loaded atom) at a distance of approximately one meter.
“Our experiment demonstrates that the processing of quantum information distributed by the network is feasible with current technology. Climbing quantum computers remains a formidable technical challenge that will probably require new physical ideas, as well as an intensive engineering effort in the coming years,” Said Mr. Lucas.

What is quantum teleportation?
In simple terms, quantum teleportation implies sending information from one place to another using something called “quantum entanglement.” Think of tangles as an invisible twin connection where two particles, even if there are miles away, are linked in a way that happens to one instantly affects the other. Unlike sending a physical object, it is sending the state or condition of a particle.
In December, scientists in the USA said that they had achieved quantum teleportation on the standard fiber optic cable that already carries the daily Internet traffic. The successful demonstration was carried out in real world conditions, showing the practical viability of quantum communication together with the traditional data transmission.
