QUANTUM ENTANGLEMENT & QUANTUM COMPUTING.

Formulated by Werner Heisenberg in 1927, the UNCERTAINTY PRINCIPLE states that we cannot know both the position and speed of a particle, such as a photon or electron, with perfect accuracy; the more we nail down the particle's position, the less we know about its speed and vice versa.

A similar uncertainty principle also applies to problems in pure math and classical physics—basically, any object with wave-like properties will be affected by this principle. Quantum objects are special because they all exhibit wave-like properties by the very nature of quantum theory.

Quantum law comes into play in the quantum world because subatomic particles can behave like waves. A common misconception about the uncertainty principle in quantum physics is that it implies our measurements are uncertain or inaccurate. But that is not so at the macroscopic level. In fact, uncertainty is an inherent aspect of anything with wave-like behaviour which the sub atomic particles have.

Now firstly Quantum theory is applicable for microscopic particles. There is a phenomenon known as QUANTUM ENTANGLEMENT.

Quantum Entanglement is an amazing phenomenon by which two microscopic particles at a massive distance which may even be billions of light years apart are linked in such a way that a change in one particle reflects in the other instantaneously. Now this does not get affected by the distance involved. This actually defies the theory of Einstein that nothing can travel faster than light because the change is instantaneous irrespective of the distance involved.  Einstein called this phenomenon spooky.

QUANTUM COMPUTING: This branch of computer science is based on the principles of the superposition of matter and quantum entanglement and uses a different computation method from the traditional one. In theory, it would be able to store many more states per unit of information and operate with much more efficient algorithms at the numerical level.

In a binary world consisting of ones and zeros, quantum computers would be like the Albert Einstein of computing, with extraordinary electronic brains capable of completing tasks that would be almost impossible for ordinary computers to handle. 

The multinational IBM will be the first to market this wondrous technology with the Q System One, a 3x3-metre glass cube with 20 cubits presented in 2019. IBM revealed a bigger quantum computer consisting of 53 cubits in 2019 itself.
