A major milestone in quantum computing has been achieved after researchers at Oxford University built a scalable quantum supercomputer capable of quantum teleportation.
The breakthrough focuses on the so-called scalability issues of quantum computing, and researchers argue that it can enable next-generation technologies at the level of disruption of industry.
The field of quantum computing has been around for decades, but only in recent years there have been significant advances in making them happen on a practical scale.

Taking advantage of the properties of quantum physics, these next-generation machines replace “one” and “zero” which are used to store and transfer digital information. At the same time, through a phenomenon known as superposition.
This makes Quantum Computers more orders of magnitude more than today’s latest supercomputers using traditional computing technology.
It is not the first time a scientist has achieved quantum teleportation. The team previously transferred data from one location to another without moving Qubits. However, across the network link, it is the first demonstration of quantum teleportation of logic gates, the smallest component of the algorithm.
Researchers argue that quantum teleportation technology could form the basis for the future “quantum internet”, which would provide an ultra-secure network for communication, calculation and sensing .
“The previous demonstrations of quantum teleportation focused on transferring quantum states between physically separated systems,” Dougal Main said from the Faculty of Physics at Oxford University, which led the research. Ta.
“In our study, we use quantum teleportation to create interactions between these distant systems. By carefully tune these interactions, we can create a queue housed in individual quantum computers. Bit-to-bit, you can perform logical quantum gates, the basic operation of quantum computing.
“This breakthrough allows a clear quantum processor to be effectively ‘wired’ into a single, fully connected quantum computer. ”

Researchers also showed that quantum systems can be built and scaled using already available technologies.
Professor David Lucas, lead scientist at the UK Quantum Computing and Simulation Hub, said:
“Expanding quantum computers remains a frightening technical challenge that will likely require new physics insights and intensive engineering efforts over the next few years.”
The findings were published in the journal Nature, a study entitled Quantum Computing Distributed across Optical Network Links.
