"Scientists at Oak Ridge National Laboratory have developed the first chip that integrates key quantum photonic components to generate and manipulate entangled photons, advancing efforts toward a scalable quantum internet. This breakthrough enables transmission of quantum information over existing fiber-optic infrastructure, using mass-producible chips to reduce cost and complexity. (Artist’s concept.) (ScitechDaily, Scientists Build First All-in-One Chip for Quantum Internet)
The quantum internet is extremely safe. Data that travels in the quantum network is connected to particles. If somebody tries to steal data that causes the qubit the particle that transports data will lose it. If somebody looks at the data. It travels out of the qubit. In regular encryption, the system just disturbs the data into new order.
Quantum encryption means that the system denies the access to the data. In the simplest versions. The system can transport data in hollow laser beams. The data transportation laser sends data in the hollow laser beam. That denies outsiders to see data. That travels in the system.
Both quantum computers and quantum networks require a new type of infrastructure. Old-fashioned copper- and light cables are useless if the system must transport qubits in the network. One of the solutions can be fullerene nanotubes. Qubits transport information in those nanostructures.
The idea is that the system loads information to the photon. And then. That photon will travel inside the nanotube. The problem is that those nanotubes must be very long. Replacing copper and light cables using nanotubes is not a cheap solution. The nanotube is also very hard. And that makes it hard to put them into curves.
Another way to close this problem is to make a quantum wire that looks like a tapeworm. The structure of the quantum network would be a series of quantum chips. That thing makes the structure. That is a combination of the quantum computer and data transportation system. The system transports information in a series of superpositioned and entangled photons. The cable itself acts as a data-handling tool.
That segment-chain computer can have two ways to handle data. The electric- or photon-electric binary system prepares those quantum chips to transport qubits. The system can transport data without changing or processing it. But it can also operate as a quantum computer.
The system can act as a series. In that model, the quantum chips send information back to the beginning point when data travels through them. The system stores that data in mass memories. It can compare data that travels in two separate chains. Because. Information travels in that quantum chip chain in stages.
The system recognizes if there is a difference in data. The data-handling process happens in stages. And the system recognizes where the error begins. That kind of "intelligent cable" would be one way to make a quantum computer that can transport information between two points.
