The interaction with qubit and solid memory is a key element in a compact quantum computer.

The key element in quantum computing is how to make a qubit interact with a computer's mass memories. If that thing is solved, researchers are one step closer to the compact-size quantum computer. And researchers made this advance. They put a qubit to interact with the solid memory unit. And that thing can turn quantum computers more effective than they are today. The ability to make solid binary memory straight with qubit opens the road to new systems that are more effective than they are today. 

The main problem with quantum computing is how to turn the binary bits into qubits. Or load them into the particle that can transport that data over the quantum network. The quantum computer and quantum internet are tools that can turn computing safer and more effective. The quantum network can be based on two possible things. The system can shoot ions, electrons or some other particles through nanotubes or hollow laser rays.

Or those systems can make a series of quantum entanglements through the quantum network. Quantum entanglement is somehow misunderstood when a particle is in two positions at the same time. The term quantum entanglement means that information that is stored in those particles can be in two places at the same time. The information is like waves on the particles, and those waves turn identical in quantum entanglement. 

There is a possibility to make a series of quantum entanglements. That requires that the energy levels in receiving particles are lower than those of transmitter particles. Or the system must store the data in mass memories so that it can create new entanglement in the case that the energy levels between transmitting and receiving particles are too close. 

So if that thing is made between two elementary particles, that means the entanglement almost multiplies the sender particle. But the problem is in the Pauli Exclusion Principle. There are no two identical fermions in the same quantum system. That means the particles in the quantum entanglement are almost identical, but their energy levels are different. 

That means the receiving particle must be at a lower energy level than the transmitting particle. If those particles reach the same energy level, it kicks those particles away from each other. 

The quantum internet is one of the next-generation computing tools. That thing makes it possible to make a secure and effective data transportation system. If that quantum system will be in use someday. That makes the internet more secure and harder to break. When data travels in a physical object. It is hard to steal. If data is stolen, it means that qubit has lost that data. And that tells that thing about the eavesdropping. If data travels in many routes, one stolen qubit will not let an attacker see the entire message. And that makes the quantum internet more secure than the traditional internet.
