Oxford Scientists Achieve Breakthrough in Quantum Teleportation, Paving the Way for Quantum Internet Development

Researchers at Oxford University have achieved a breakthrough in quantum teleportation, successfully transmitting quantum logic gates – the basis of calculations – over greater distances.

This step could be key to creating a "quantum internet," ensuring secure communication and distributed computing.

Unlike classical bits, which store data as 0 or 1, qubits can exist in both states simultaneously due to quantum superposition.

This gives quantum computers a huge advantage in processing complex tasks.

Quantum logic gates operate differently than traditional logic circuits, allowing parallel calculations.

British researchers have demonstrated the ability to transmit quantum gates, enabling the connection of remote processors into a single computing system.

Lead author, Dugald Main, explained that their method allows not just data transfer between systems, but also effectively "wires up" remote quantum processors.

In experiments, researchers ran Grover's algorithm – a method used for fast searching in unsorted databases – and achieved success in 71% of cases.

The development of quantum teleportation is progressing in parallel with efforts to create a full quantum internet.

A team from Harvard was able to transmit "quantum entanglement" over a distance, which is important for creating secure communication networks.

Entanglement allows particles to exchange data instantly, even if they are separated by large distances, making quantum information transfer impossible to intercept.

The Oxford experiment used two modules with ion traps, containing two types of qubits: "network" for communication and "computational" for data processing.

These modules were connected by photons, creating a common quantum state, and the teleportation of quantum gates allowed them to work as a single system.

Despite significant achievements, the technology is still far from mass application.

The reliability of transmitted quantum gates reached 86%, but practical use requires a level above 99%.

Scientists believe that further research will help overcome this barrier, paving the way for supercomputers and absolutely secure communications.

This breakthrough confirms that the future of quantum computing is not just faster algorithms, but entirely new principles of data processing that can transform everything from cryptography to artificial intelligence.
