# How Quantum physics supports Heisenberg principle

Some quantum physicists believe that there are unspecified things in the universe. Rather, most physicists believe that nature itself is not certain about it, and on top of them is Werner Heisenberg who developed the “principle of uncertainty” that goes to the impossibility of knowing all the properties of a particle at one time. If the position of the particle is known, for example, why Learn its speed with an error proportional to the accuracy of the position measurement.

Heisenberg adopted his principle to explain a phenomenon in the double-slit experiment, which is an experiment in which quantum particles are projected onto a corresponding plate, through two slits in a middle plate, without any certainty of which slit each particle passes through (its position). Particle distribution on the flap.

If a device is placed to see which slit the whole particle has passed through, the interference pattern is removed.

This is what Heisenberg explained with his principle, saying that knowing the particle’s position destabilizes its velocity, destabilizes its position on the opposite plate, so that there are no ripples of interference.

## Heisenberg principle that explained the disappearance of the interference pattern

But physicists devised a positioning device that seemed to not affect the velocity of velocity, that random effect, so they concluded that it was not Heisenberg’s principle that explained the disappearance of the interference pattern, but rather another mechanism. Even an international team recently published a research paper saying that this conclusion was an acceleration, and that they conducted an experiment that showed that speed is affected exactly as Heisenberg predicted.

“The velocity acceleration does not occur while a particle passes through the measuring device, but rather after it passes the two slits a relatively large distance … The reason for this is that quantum particles are not just particles, but they are,” said Howard Weizmann, director of the Center for Quantum Dynamics at Griffith University, and one of the researchers. Particles and waves at the same time. ”

The team used an approach proposed by Weizmann in 2007, and compared the velocities over time, both when the measuring device was present and when it was not present, and in this way determined the change in velocity as a result of the measurement. He discovered that the effect of velocity with the position measurement continued even after the particles had passed the same measuring device, at five meters.

This not only supports Heisenberg’s principle, but also reminds one of the consequences of haste, and warns scholars not to judge any principle until after carefully considering all its possibilities and theoretical formulations.

**Heisenberg **principle or **The Uncertainty Principle**

And as you know the uncertainty principle is certainly one of the most famous aspects of quantum mechanics. It has often been regarded as the most distinctive feature in which quantum mechanics differs from classical theories of the physical world. Roughly speaking, the uncertainty principle (for position and momentum) states that one cannot assign exact simultaneous values to the position and momentum of a physical system. Rather, these quantities can only be determined with some characteristic “uncertainties” that cannot become arbitrarily small simultaneously. But what is the exact meaning of this principle, and indeed, is it really a principle of quantum mechanics? (In his original work, Heisenberg only speaks of uncertainty relations.) And what does it mean to say that a quantity is determined only up to some uncertainty? These are the main questions we will explore in the following, focusing on the views of Heisenberg and Bohr.

## Fundamental concept in quantum mechanics

The Heisenberg uncertainty principle, also known as the uncertainty principle, is a fundamental concept in quantum mechanics that describes the relationship between certain pairs of physical properties of subatomic particles, such as position and momentum, or energy and time. The principle states that it is impossible to precisely know both the position and momentum of a particle at the same time, and that the more precisely we measure one property, the less precisely we can know the other. This is not a limitation of our current technology, but a fundamental property of the universe.

## One unique aspect of the Heisenberg uncertainty

One unique aspect of the Heisenberg uncertainty principle is that it challenges our classical understanding of physics, which assumes that objects have precise values for all physical properties. In the quantum world, however, properties are described by probability distributions, and our knowledge of these properties is always limited by the uncertainty principle. This has profound implications for how we understand the behavior of subatomic particles and the nature of reality itself.

## Heisenberg uncertainty and quantum cryptography

One such application is in quantum cryptography, where the uncertainty principle is used to ensure the security of communication channels by encoding information in the properties of individual particles, such as photons. The uncertainty principle helps prevent eavesdropping, as any attempt to measure the quantum state of a photon without disturbing it will necessarily introduce uncertainty, alerting the intended recipient of the communication.

Another application of the uncertainty principle is in the concept of quantum tunneling, where a particle can “tunnel” through an energy barrier that classical physics would predict it could not overcome. The uncertainty principle plays a crucial role in this phenomenon by allowing for the existence of virtual particles that can briefly violate energy conservation, allowing a particle to tunnel through an energy barrier.

Overall, the Heisenberg uncertainty principle is a fundamental concept in quantum mechanics and has numerous applications in a variety of fields, including cryptography, solid-state physics, and quantum computing.

## Heisenberg uncertainty and quantum computing

In quantum computing, the uncertainty principle plays a crucial role in the concept of superposition, where a quantum bit (qubit) can exist in multiple states simultaneously.

The uncertainty principle sets a fundamental limit on the accuracy with which we can measure the state of a qubit. This means that as we perform operations on a qubit to manipulate its state, the uncertainty in its position and momentum increases. As a result, the qubit’s state becomes more and more uncertain, which can lead to errors in quantum computations.

However, researchers have found ways to work around the limitations imposed by the uncertainty principle. For example, by using quantum error correction codes, it is possible to detect and correct errors that arise due to the uncertainty principle. Additionally, techniques such as quantum state tomography can be used to estimate the state of a qubit despite the uncertainty introduced by the uncertainty principle.

Overall, the Heisenberg uncertainty principle is a fundamental principle in quantum mechanics that has important applications in many areas, including quantum computing, cryptography, and solid-state physics.
