Every morning we drink Coffee.
Which is a potential source of Caffeine.
Do you know?
That a Caffeine molecule contains so much information about it's atomic structure
that it could take upto ten to the power forty eight bit to store them.
But a special computer can do it with only one sixty qubits.
Can you guess that magic computer?
Yes my brothers and sisters it is Quantum Computer.
Here is a little demo how a Quantum Computer works.
The server receives informations from the user and converts it into machine language.
Then,specific analog electronics transform them into electronic pulses.
which are send to the quantum processor,there the processor executes the problem
and sends it back to the user.
Actually, fundamental difference betweens a Quantum Computer
and a Classical computer is that,
Quantum Processor uses qubits where Classical Processor uses bits.
Here, every information we use is just interaction between millions of bits.
Bits can be represented as 0 1 or switch on off.
Bits are just blips of electricity.
But in quantum Computer qubits can be 0,1 or both at the same time
using Quantum Super Position property.
Quantum Super Position allows a qubit to be in many states once at a time.
Just like a coin in the air.
So, Before that they must be isolated and cold down near to absolute zero kelvin
to avoid any quantum  error.
So, what's the use of quantum Computer? The answer is in everywhere in everything lets talk about some.
Due to Corona Virus the world is being more challenged then ever before.
If we look at it we will see this Glycoprotein Spikes
that can be modeled and restore more efficiently by Quantum Computer
and it can help us finding molecules to make Vaccines.
Also different kinds of Quantum Algorithms and pricing circuits like
Portfolio Optimization Algorithm can save the investors from bankruptcy
and the country from another rescission like 2009.
Another use is Data Encryption whenever we use credit cards on Amazon they are bing encrypted
using 2048 bit RSA Encryption Method. But that can be broken down with Quantum Computer
in just 100 seconds. So what's the solution?
that is Quantum Cryptography known as Quantum Key Distribution.
Suppose me and Sherlock Holmes are transmitting an encrypted message on a normal secured channel.
And send the key to decrypt the message through an Entangled Quantum Channel.
But professor James Moriarty is trying to steal the message.
Luckyly, professor Moriarty's attempt to intercept will allow the key to be discarded
and retained again through another quantum channel.
Thus, Quantum Key Distribution always secure our data.
Present improvement of Quantum Computer can be compared with
the first flight of Wright Brother's .
So, there needs alots of work to do.
However when nature gives you Lemon, why Don't you make Lemonades?
