  The two notable terms that attract people to quantum physics are superposition and entanglement. These two characteristics really have a significant impact on quantum computing. Superposition and entanglement will be utilized in quantum communications and information storage, respectively, in the future. Computers were typically controlled in bits, which are represented as 0 or 1. On the other hand, quantum computing makes use of quantum bits, or qubits, which exist in a condition known as the superposition state, which is a combination of 0 and 1. Let’s imagine that we can anticipate both a head and a tail result when a coin is thrown. However, a coin can exist in both the head and tail states in a quantum world. In physics, you may have studied the dual nature of light. We discovered that light behaves as both a wave and a particle in Young’s Double Slit Experiment with Interference Pattern. The method of experimentation determines the character of light. demonstrated how light...

 Einstein’s paper with his two postdoctoral research companions, Boris Podolsky and Nathan Rosen, was the great EPR paradox .”Can Quantum Mechanical Description of Physical Reality Be Considered Complete?” asks the paper.(1935). You might be surprised to learn that Einstein was the one who laid the groundwork for quantum mechanics in its early stages, only to propose that quantum physics is incomplete. Some refer to this as Einstein’s great mistake, which led to a tremendous quantum discovery. In this blog, I will discuss EPR briefly. However, it takes a fundamental understanding of quantum characteristics, which I am here to simplify. Even now, this study is regarded as one of the top ten most influential publications ever published in the field of physics. The argument over EPR continues to this day. One common misconception is that quantum communications are faster than or close to the speed of light, which is not true. EPR proposes something similar. This contradiction is argue...

While bits are nothing new to us, the term “qubit” may be unfamiliar to some. Similar to classical information, the fundamental building block of a quantum system is the quantum bit, or qubit. Qubit and its features are defined and discussed in this blog. To store data in quantum computers, we employ a basic building block called a qubit. In contrast to bits, which exist in binary states like 0 or 1, qubits exist in quantum states like |0⟩ and |1⟩ and they can exist in superposition of these two states as well.                                                                            |ψ>=α|0⟩+β|1⟩, where α and β are complex numbers. which represents probability amplitudes of corresponding basis state. The state will initially at |ψ> and upon measuring the sys...

  I was first introduced to the world of quantum mechanics through popular media like Marvel movies and online videos. As I advanced in my higher education, I found myself increasingly fascinated by the fundamental principles of quantum physics. What I realized is that the actual facts and phenomena, like quantum tunneling, quantum teleportation, quantum algorithms, quantum machine learning, quantum communication, etc., within the realm of quantum mechanics are often more astonishing and mind-boggling than the speculations and mysteries that occasionally surround them. One captivating example of this is the intriguing concept of quantum teleportation. The concept of quantum mechanics has generated a significant amount of excitement among people from various backgrounds. Quantum is no longer confined to the realms of science fiction or specialised scientific knowledge. This article aims to introduce the origins of quantum mechanics in simpler terms without delving too deeply into co...
