## QUANTUM COMPUTER

In today's era, it has become impossible to think without a

**. Why don't we take any field, such as space exploration, any kind of research in the medical field and in long calculations, the use of computers is necessary everywhere. We have not only reduced its size to the smallest in the last few decades but also increased its computation power. We can take an example from this when the first computer was built, its size was as big as one room and today it is in our palms as a smartphone. Even our present-day smartphones are far ahead of the computing power of previous computers and their storage capacity is also very large. It is not that today's computers and smartphones do not have limitations. According to today's expectations, computers sometimes fall behind. In some complex calculations, the calculation speed of these processors lags far behind. And then to solve this problem we need to have a "***Computer***".***Quantum Computer***are computers that use "**

*Quantum Computers***" or "**

*Quantum Beat***" to perform calculations. Now one thing will be in our mind that what is a "**

*QBit***"? In simple language, whatever operations or work is done in our present-day computers, our computers only understand them by**

*QBit***"0"**and

**"1"**. Which we call

**Binary Code**. And that's why we call computers of this type as

**. Similarly,**

*Binary Computers***use**

*Quantum Computers***for calculations.**

Let us understand this in easier language. The processor
uses transistors to perform any task in a binary computer. All transistors are
always in on state or off state. The

**ON**state is considered**"1"**and the**OFF**state is considered**"0"**in the**. Whatever command we give the computer for running a program or algorithm, the computer converts all the commands into 0 and 1 and performs the task***Binary Bits*
.

The

**always gives the answer***Binary Computer***"1"**or**"0"**by using the condition of**"0"**or**"1"**at a time. But in the case of**, it is a little different. The***Quantum Computers***uses***Quantum Computer***. These Qbit have an extra function which is not present in***"QBit"***.***Bit*
Actually, in the case of

**, the information exists in only two states, either***Bit***"0"**or**"1"**. But in the case of**, the information is in state***QBit***"1"**or state**"0"**or**"in-between 0 and 1"**and the state is called**. So the advantage is that a developer can check [if "0"] condition, [if "1"] condition or both [if "0" and "1"] condition.***"SUPERPOSITION"*
To understand this, we take an example of a coin. If we
hoist a coin upwards, then the probability of head or tail is only 50%. The
result may be head or tail. But in the case of

**, the result can be head, it can be a tail, or it can be both head and tail unless and until it observes. The exact proof is found in the***Quantum Bit***.***Schrodinger's Cat Experiment*## QUANTUM SUPREMACY
