Strange aspects of the universe revealed by quantum physics

The term quantum seems to be used all the time. There are quantum computing and quantum internet. Quantum cryptography. There are all areas of quantum physics. And there is even the phrase achievement. But what does it mean? Is that jump particularly high? What’s the problem?

In fact, the progress is surprisingly small. The word quantum refers to the minimum amount of things you can have. You cannot divide the amount of something into smaller pieces. Quantum is the most basic component.

If you are interested in the little things that scientists know, this is something you should know. They are very rude. But this is not surprising. Your home is a quantum world.

The matter of these elementary particles does not follow the same rules as the objects we can see, feel and hold. These creatures are ghosts and strange. Sometimes they behave like masses of matter. Think of them as elementary particle baseball. They can also spread like waves in a pond.

They can be found everywhere, but the certainty of one of these particles in a particular place is zero. Scientists can predict their location but do not know where they are. (For example, this is different from baseball. If you put it under the bed, it will see that it is there and will stay there as long as you move it).

The bottom line is that the quantum world does not work the way the world around us does, says David Lindley. We really have no idea how to deal with it, he says. Lindley, who trained as a physicist, is writing a book on science (including quantum science) from her home in Virginia.

It tastes weird: when you hit a baseball in the pool, it flies into the air and lands on the opposite shore. When you throw the baseball into the pond, the waves rise like waves. These waves eventually reach the other side. In either case, something is moving from place to place. However, baseball movements and waves are different. Baseball does not wave when moving from place to place and does not form mountains or valleys.

In experiments, however, particles in the universe of elementary particles can move like waves. And sometimes they move like particles. It is not clear to anyone why the smaller laws of nature work this way.

A photon

Consider a photon. These particles make up light and radiation. They are small packets of energy. Centuries ago, scientists believed that light traveled as a stream of particles, much like the flow of glowing tiny bullets. And in an experiment 200 years ago, it was shown that light is transmitted in the form of waves. One hundred years later, new experiments showed that light could behave like a wave or a particle called a photon. These discoveries have caused a great deal of confusion. And talk and headaches

Wave or particle?

Wave or particle? Neither or both? Some scientists have used the word wavicle to reach a compromise. How scientists respond to questions depends on how they try to measure photons. You can set up an experiment in which photons behave like particles and an experiment in which photons behave like waves. However, it is impossible to measure them simultaneously in waves and particles.

This is one of the weirdest ideas that come out of quantum theory. Photons do not change. Therefore, it does not matter how scientists study them. You need to look not only at the particles but also at the waves you are looking for.

Do you really believe that the moon only exists when you see it? Albert Einstein famously asked. (German-born Einstein played an important role in the development of quantum theory.)

However, this problem is not limited to photons. It expands into particles that are smaller or smaller than electrons, protons, and other atoms. All particles have both wave & particle properties. This idea is called corrugated particle duality. This is one of the biggest secrets when studying the smallest parts of the world. This is a field known as quantum physics.

Quantum physics Future

Quantum physics will play an important role in future technologies. A typical computer uses billions of switches embedded in a microchip to perform calculations. These keys are on or off. However, quantum computers use atomic or subatomic particles in their calculations. Such particles can be on, off or somewhere in between, because they can multiply at the same time, at least until they are measured. This means that a quantum computer can perform many calculations at the same time. Their speed can be thousands of times faster than today’s cars.

Two major technology companies, IBM and Google, are currently developing ultra-fast quantum computers. IBM even allows overseas to conduct experiments on their quantum computers.

Do not worry if quantum theory sounds strange. You are a good companion. Even a well-known physicist scratches his head.

Do you remember the German genius, Einstein? Helped explain the quantum theory. And he often said that he did not like it. He has been discussing it with other scientists for decades.

If you can think of quantum theory without dizziness, you can’t understand it, wrote Niels Bohr, a Danish physicist. Bohr was another pioneer in this field. He had a famous discussion with Einstein about how to understand quantum theory. Bohr was one of the first to explain the strange things about quantum theory.
