The minimum time that the quantum gate needs to react is the time that is the absolute limit for quantum computers. The quantum gate is the gate that cuts the data line, and the speed of that gate is the thing that determines the maximum speed of quantum computers. 

The fact is that all people who worked with quantum technology know that there are speed limits even for quantum computers. The speed of light is not the problem because long-distance superposition and entanglement between particles can surround the cosmic speed limit. But if we want that the superpositioned and entangled particles would bring visible or meaningful benefit for quantum systems. 

The distance between the systems must be enormous. The thing is that superpositioned and entangled particles are acting as quantum sticks. When another side of quantum entanglement is moving also other side is moving. But that thing doesn't remove the need for a quantum gate. 

So it separates the data packages and sends them to the right addresses. But the thing is that the quantum gate (quantum logic gate)  is more complicated than the gate (logic gate). 

The speed of that gate is enormous. But always when there is something that has mass. The speed has limits. One of the solutions for increasing the speed of that gate could benefit things like some atoms. The system can pump energy to the atom. And that thing can cause that the size of an atom can change. 

That thing can cut the photonic interaction. The other version is to use hydrogen atoms, and then the electromagnetic stress will cause changes to the trajectories of electrons. That thing can let the energy travel through protons and electrons. 

The error correlation is the problem with quantum computers. The error correction is the thing that is necessary for making a practical quantum system. The answer is to use two quantum systems that are getting the same data. The splitting photons can make sure. The data that is sent to two quantum systems is identical. 

And if there is some kind of difference between the answers. There is some kind of anomaly in the system. If the answers are also identical. The answer should be correct. And when the number of data handling lines increases. The possibility to find errors is also increasing. That increases the trust and accuracy of the quantum systems.

Antimatter motor

Antimatter motor Antimatter would be an effective fuel for interstellar spacecraft Antimatter would be the most effective power source in the world. It will be the most suitable motor for interstellar spacecraft, but the problem is that thing is very reactive. And actually one of the biggest problems with this kind of motor is that the gram of antimatter would turn the entire planet to the molecular nebula. So this kind of motor can produce only outside of our solar system. Producing antimatter would need large particle accelerators, and that kind of systems might look like giant donuts, what is floating on the space. There are two ways to create the antimatter motor, one is to store the anti-ions in the magnetic bottle, where the pushing magnetic field will keep those ions away from the wall of the bottle, and then the antimatter would conduct to the water or some other particle. The huge explosion or annihilation reaction would send the rocket to a very high speed. The antimatt...

Could this be the thing, that some people don't want you to know about zombies?

Could this be the thing, that some people don't want you to know about zombies? The simplest way to control zombies, which are made by using tetrodotoxin, which is called "zombie poison" is to use the automatic dispenser, which is normally used in diabetes treatment. In this case, the dispenser would be loaded by using tetrodotoxin. If the level of this poison is right, the person would be totally under the control of other people. And if the system cannot detect this poison there is a possibility to make the laboratory experiment when the staff will follow the decrease of the tetrodotoxin, and then the system can use a simple clock, which will inject poison to the body of a victim after a certain time. This would be an effective tool in the hands of military and counter-terror operators. Those zombies can be captured enemy operators, who will send back, and then they just kill their ex-partners. By using genetically engineered bacteria could be possible to create t...

Who really was Plato, the great philosopher?

When we are thinking about the great philosopher Plato, we are thinking about the man who established the Academy of Athens. And we might remember that this man was a traveler. He traveled in many places in his life and wrote many texts and books, which still is very respected thoughts about the state and other things. When we are looking at the books or series of books, we are facing the thing, that there were lots of texts. If we want to use criticism we must notice that the model of the ideal state is rising the kings in the very high position, and the thing would flatter the kings. And sometimes I have thought that maybe that famous model of the ideal state is written by somebody else. The thing is that the model, where the philosophers rule the state behind the lines of soldiers could be written for the persons like Justinian, who was really flattered. The thing is that this kind of writings was meant for flatter the rulers, who would not persecute philosophers, even they had d...
