Scientists have developed simulation of the rapid process of studying quantum theory, revealing the mystery of quantum entanglement and its mysteries.The results of these research detailed how to quantify and observe entanglement within several Att seconds, indicating that significant progress has been made in understanding the time dynamic of quantum events.

Quantum theory and time: Reveal the instantaneous effect
The quantum theory involves extremelyIncidents that occur within a short time scale.In the past, these incidents were considered instantaneous, and there was no time interval in the middle: an electron was running around the atomic nucleus, and in a blink of an eye, it was suddenly shot by a flash.Similarly, "quantum entanglement" will occur immediately after the two particles collide.
However, today, scientists can study the exact time of these almost instantaneous effects.Researchers at Tu Wien cooperated with teams from China to develop computer simulation to explore these ultra -fast processes.Through these simulations, we can understand how the quantum entanglement is formed in just a few minutes.Their research results were published in Physical Review Letters.
A second is a minimum of time, only one billionth of 5 billion (one billionth of one billion, or 10-18)EssenceIt is usually used to measure the super fast phenomenon in quantum physics, such as the movement of electronics in the atom.
If the two particles are entangled in quantum, then it is meaningless to describe them.Even if you point the state of this dual -granulated system, you cannot clearly describe the state of a single particle."It can be said that particles have no separate attributes, they have only common attributes. From a mathematical point of view, even if they are in two completely different places, they will firmly combine together.Professor Joahmm Bergoli explained.
In the experiment of entangled quantum particles, scientists usually want to maintain this quantum entanglement as much as possible-for example, if they want to use quantum entanglement for quantum cryptographic or quantum cryptography orQuantum computer."On the other hand, we are interested in others-find out how this entanglement was originally formed, and which physical effects played a role in a very short time scale," one of the author of the publication Eva-Lear Jaynova said.
Time and entanglement of the birth of quantum
Researchers observed the impact of high -frequency laser veins in high frequencyAtomic.A electrons in the atom were torn and flying away.If the radiation is strong enough, the second electrons in the atom may also be affected: it may be transformed into a higher energy state, and then run around the atomic nucleus with different paths.
Therefore, after the laser pulse, one electron flew away, and the other electron was left in the atom with unknown energy."We can prove that these two electrons are now entangled in quantum. Only by analyzing them together, we can measure one of them.At the same time, learn about some of the situations of another electron.The situation, that is, the "birth time" of the flying electrons (that is, the time to leave the atom) is related to the state of the electrons.These two characteristics are quantum entangled.
"" This means that the birth time of flying electrons is in principle unknown. It can be said that the electron itself does not know when it leaves the atom, "Erfel said."It is in different states of quantum physics. The time point for it to leave the atom is both early and late."
We cant answer "real" the "actual" answer that does not exist in quantum physics at all in quantum physics.But the status of the answer with the remaining electrons in the atom is not determined-there is a quantum physical connection: if the remaining electrons are in a high energy state, then the flying electrons are likely to be torn out at the earlier point in time.; If the remaining electrons are in a lower energy state, the "birth time" of the free electrons flying away is likely to be late-an average of about 232 Ah.
"" This is almost an unimaginable short time: One second is one billionth of one -second.I have negotiated with the research team that proves this ultra -fast entanglement.When trying to analyze the ultra -short time scale of these effects, the important correlation will appear."Electronics is not jumped out of the atom. It can be said that it is a wave overflowing from the atom, and it takes a certain time," Eva-Butujin Nova said."It was entangled at this stage, and then accurately measured its effect by observing two electrons."
