The quantum networks can also have vulnerabilities.

The thing that makes the quantum network so secure is this. Information that travels in that network is connected to physical particles. When the energy level at both ends of the quantum entanglement reaches the same level. The system must make the new superposition and quantum entanglement. Before that, the system must separate information from the quantum entanglement and store it. And that mass memory where the system stores information is the weak point. Also. Things like graphics cards that output information to the screen can be vulnerable to attack. In the same way. The attacker can focus the attack. On binary systems that control the quantum computer. 

The researchers say that every system has holes. So, if the system exists. It's possible to break. There is always a weak point in the system. In the best systems, the user is the weakest point. The weak point in quantum computing is that. Those quantum computers are used. Through binary computers. 

The attacker can focus the attack on the binary system that controls the quantum computer. The output route that prints the solution to the screen of a binary computer can be infected. Using a Trojan horse. This means the quantum system will not be breakable. But the binary computers. That handles input-output traffic. Are. Same way. 

Vulnerable as other binary computers. The vulnerable point in the system can be the graphics circuit, which controls screens. And things that the system outputs to the screens. 

That weak point can be the router; there is mass memory. That the system uses. When it creates a new quantum entanglement pair. When information travels in a quantum network, in most models. It travels in a chain of superpositioned and entangled particle pairs. The problem with quantum entanglement is this. 

The transmitting side of the quantum entanglement must be at a higher energy level than the receiving particles. When those particles reach the same energy level, that breaks quantum entanglement. So in the high-class quantum network, the system must re-adjust the quantum entanglement. Information always travels straight through quantum entanglement. The quantum network means the fullerene nanotube. That protects quantum entanglement when it transmits information. 

If there is a curve in the quantum entanglement. That requires that. The router receives the information that it gets. Then it creates another quantum entanglement. And re-transmits data. For that process. The system must store information before it makes the new quantum entanglement in the chain. This memory block can be the target for attackers. The idea is that the router should make the new quantum entanglement. And then resend that data. That is stored in it. 

The weak point of the quantum network is the point where the network re-adjusts quantum entanglement. The easiest way is to make a new superpositioned entanglement. But. For that process, the system must store the information that it transports. 

"Despite being continually kicked and strongly interacting, the atoms no longer absorb energy. The system localizes in momentum space, the momentum distribution literally freezes, a remarkable phenomenon termed many-body dynamical localization (MBDL). Credit: Universität Innsbruck." (ScitechDaily, Physicists Discover a Quantum System That Refuses To Heat Up)

The quantum system that will not heat. It is one of the things. That can make the new types of quantum networks possible. This system. It can make the longer-lasting quantum entanglements possible. The experiments show that the ultra-cold atoms do not always heat up as expected. This means. That is the quantum entanglements. Those who are targeted. Photons are trapped on those atoms. 

Can keep. a quantum entanglement. A very long time. The idea is that the ultra-cold atom transports energy out from the quantum entanglement’s receiving part. This means that stable quantum entanglement is theoretically possible. 

And then. We can think about the thing. Called the gravothermal collapse. That causes a situation where the hypothetical dark matter halo turns hotter when it releases energy. The reason for that is that the dark matter structure turns smaller. And because particles are closer to each other, that makes energy denser in that structure. At the same time, those hypothetical weakly interacting massive particles (WIMPs) send energy. 

This causes a situation where gravity pulls those particles closer. To each other. And the energy is released into a smaller area. So, in a gravothermal collapse. The same number of particles sends energy into a smaller and smaller area. And that warms the structure. 

It would be interesting to think about the possibility. Is it possible that there is a so-called electromagnetic or quantum-size version of the gravothermal collapse? In the model, there is a possibility. That is when the electrons fall to the atom’s nucleus in the Bose-Einstein condensate. They should behave as WIMPs interact in gravothermal collapse. This means when electrons release photons and energy. In the smaller-scale structures. That energy level or energy density rises. 

So, if researchers could control the distance of electrons. Between each other and the distance of electrons to the atom’s core. That can deny the heat effect in the smaller-scale atoms. Or it denies the energy density. Rise in the atoms when their electrons fall to the core. Rise of. The energy density means that a certain number of particles sends a certain number of energy quanta. Into a certain area.
