THE CHINESE HAVE TAKRN A BIG LEAP

Free understanding on Heisenberg Uncertainty principles

One of those principles that make sub atomic particles illusive was predicted by Heisenberg. It is called the uncertainty principle. Introduced first in 1927, by the German physicist Werner Heisenberg, it states that the more precisely the position of some particle is determined, the less precisely its momentum can be known, and vice versa. You remember I once described PMB economic principle as uncertain as Heisenberg uncertainty principle. Classical physics was on loose footing with problems of wave/particle duality, but was caught completely off-guard with the discovery of the uncertainty principle. But is it really true that this wave-particle duality really exist for all bodies? Me thinks so. Think of it as vibration. The question can be reframed thus “Does every body, from small things to the massive bodies like planetary system, from animals to human beings, from flowers to trees vibrate? If you expand it in this form you won’t have difficulty answering “Yes” Actually in the realm of Meta-Physics, we know this is true without any mathematical proof. Now if you walk into a room, where mischievous things have been said about you, I mean in your absence, and everybody begins to hail you and greet you, somehow, your senses will tell you that something is amiss somewhere. The actual thing that happened is that contrary vibrations have been emitted in the atmosphere, which your ‘antennae’ is just picking up. This is about how much I can go here. So, the wave-particle duality is inherent itself in nature.

Any attempt to measure precisely the velocity of a subatomic particle, such as an electron, will knock it about in an unpredictable way, so that a simultaneous measurement of its position has no validity. This result has nothing to do with inadequacies in the measuring instruments, the technique, or the observer; it arises out of the intimate connection in nature between particles and waves in the realm of subatomic dimensions.

In its purest form, the uncertainty principle states that accurate knowledge of complementarity pairs is impossible. For example, you can measure the location of an electron, but not its momentum (energy) at the same time.

You will soon know later why an understanding of this principle is important in quantum cryptography and why the Chinese said there communication from the new satellite cannot be intercepted. Just be patient.

Quantum Entanglement

Have you ever heard of body double? At least if you were old enough during the Gulf war, you should have. They told us that Saddam Hussein has a body double. Ok most recently also the Nigerian Army also said so about Shakau the BH leader. Well, quantum entanglement is much like that. It does say that I Henry has a resemblance that stays, let say, in the moon or even at Aba. However, if  I eat in Lagos, my body double will also eat in Aba or any other place it might be positioned. If I sleep, the double will sleep, if I walk, the double will walk simultaneously. There is no known transmission of the information of what I do to the double. It defies the space-time metrics. Everything happens at the same time.

Of course you know, except if you are one of those who believe such folk tales, it doesn’t happen. There are no such body doubles anywhere. But they exist in the world of quantum mechanics and that is the trick in quantum communication. A communication far away from the speed of light; but in actual fact, there is no transmission of information, it just happens at the same instant of time, no matter the distance between entangled pairs.

This theory so disgusted Albert Einstein that he called it ‘spooky action at a distance'. Einstein wasn't happy with the theory, because it suggested that information could travel faster than light.

Quantum entanglement is a quirk that seems to occur in the strange world of subatomic particles where pairs become inextricably linked together so they share the same state, even if they are separated in distance.
In quantum physics, entangled particles remain connected so that actions performed by one affects the behaviour of the other, even if they are separated by huge distances.
These states can be expressed in much the same way as binary bits from a conventional computer - ones and zeros - but are known as qubits. Quantum bits are not actually just 1s and 0s. A quantum bit represents a minimum of 4 bits of today not just one bit, because a quantum particle at least must have four different transition states.

Remember our earlier discussion, quantum particles actually exist in all possible states simultaneously until they are observed or measured, at which point they exhibit just one state.

An unauthorized hacker, for example, who attempts to take a peek at any data being sent in this way would immediately alter its state, making it impossible to copy. Remember the uncertainty principle now? Yeah! You the position and energy state simultaneously.

Ultimately, this means only the two parties who have the entangled particles are able to read the information.

This is the useful key for encrypting information that cannot be hacked.

Let’s continue our bit tomorrow, to examine the actual thing the Chinese are attempting to achieve. Remember, it is still very much experimental.
