World's First Teleportation Between Quantum Computers Achieved

Researchers from Oxford University have achieved a breakthrough in quantum technology: for the first time, a quantum state was successfully transferred between two quantum computers using quantum teleportation. Although the transfer occurred at just two meters distance in the laboratory, this achievement proves the possibility of scaling quantum computing and creating distributed quantum networks.

The work was published in Nature journal.

Quantum teleportation is based on the phenomenon of entanglement, where particles remain connected even when separated in space. By manipulating one particle, the state of another can be instantly changed, allowing quantum information to be transmitted without physical movement of the carrier.

In the scientists' experiment, the teleported quantum state was preserved with 86% accuracy, which is sufficient for performing simple logical operations on a quantum computer. This opens new perspectives for creating a quantum internet capable of connecting quantum processor modules without losing their efficiency.

"Our approach allows flexible modification of the quantum system, replacing or updating individual modules without disrupting the entire architecture," noted the study's lead author Dougal Main.

According to the scientists, their work's results could not only accelerate the development of quantum computing but also become the foundation for new research into fundamental laws of physics.
