Quantum entanglement: making the ‘impossible’ simple

The initial complexity of quantum mechanics begins with the information entering our ears and eyes. and our brain understands that we are going to talk about a subatomic, rebellious world that doesn’t seem to respond to anything classically constructed in the field of science.

In recent years, researchers have been interested in analyzing, experimenting, explaining and testing theories about the seemingly anomalous behavior of subatomic particles. But phenomena like quantum entanglement require a different way of looking at reality.

Because some of the behavioral phenomena of these particles cannot be explained by the laws that govern nature from a macroscopic perspective. Just extrapolate a little and think about every car you see on the street.

The movement of cars on a street can be well described by data on their speed, location, and relatively precise calculations of how long it will take to move along a marked route.

But if these tools behaved the way particles behave at the quantum scale, a more chaotic world governed by probabilities and quantum jumps would make our daily lives much less orderly.

This does not mean that We think that chaos governs quantum physics, but because of our biased view of classical physics, these observations seem rather exotic.. In the “quantum world” the limits of classical physics are being pushed at every moment of time. But is there a way to simplify this? Let’s try to clear up some confusion.

A node is born

One of the most recurring themes in quantum physics quantum entanglement or quantum entanglementThe name was proposed by Erwin Schrödinger in the mid-1930s, the same decade in which the “synchronous” behavior of particles was described by Albert Einstein, Boris Podolsky, and Nathan Rosen.

In their 1935 paper “Can the quantum mechanical description of physical reality be considered complete?” the trio presents the EPR paradox (Einstein, Podolsky, Rosen), in which scientists propose a thought experiment about what theories say and physical observations tell us about reality.

According to them, existing equations were not sufficient to explain the observed quantum phenomenaOne of these is what we call quantum entanglement, which is the correlated behavior between two particles in similar states of existence.

Briefly, quantum entanglement is the interconnected behavior between two particles, independent of the space between them and without the need for a physical connection between these elements.

It is as if these particles, when “born,” create a unique kind of connection that allows them to exist and act in conjunction with one another. If one spins left, its entangled particle will spin right somewhere in the cosmos..

Untangling

But how is this possible? According to Einstein, it is a ghostly force.. Although it may seem funny, the invisible connection between these particles is still not fully explained. However, the truth of this phenomenon has already been proven.

Carl Kocher, professor of physics at the University of California, has conducted experiments with entangled photons emitted from the element calcium. In fact, the associated particles respond to predicted changes in behavior, and this phenomenon can be observed not only in pairs but also in clusters of particles.

When an entangled particle is measured and “observed” its counterpart is expected to be in the “opposite” state. However, in addition, When the particle under test is forced to change its state, its bond will also instantly change its state..

Data would be processed quickly, with instantaneous exchange without the need for networks or outputs, and communications would be tamper-proof. And in this automated and highly efficient correspondence, researchers in the field are proposing practical applications that could revolutionize the way communications and quantum computing occur.

Some researchers even suggest that this communication between particles is so fast that it can exceed the speed of light. However, as far as we know, this speed is within limits, without breaking the speed of light paradox.

Also, other fields of study use the principle of superposition, where it is concluded that all particles are in all theoretically possible physical states at the same time. When we make an observation, we collapse the system by creating a certain period of time and infer the state at that moment.

Like this, Quantum entanglement can only be studied on very small timescalesprovides the observer with only a small glimpse of the connections present in the system; this will also depend on the perspective and angle of view of the person making the measurements.

Not that discrete

In the opera summary, Know that quantum entanglement is the connection between two particles or a set of particles, and once they are connected, this interconnection can never be broken..

Living in a constant state of flux and interacting with each other regardless of “real” physical connections and distance, this quantum entanglement is no closer to being resolved.

THE The subatomic world is still full of mysteriesBut science is trying to develop, though not by very great strides, to such an extent that these and many other doubts and dreams may one day be answered.
