I can tell you right now that nobody here knows a thing about that. This is an app for beginners to intermediaries. I don't even believe this is programming related. If it is, please delete your question and ask it at a Stack Exchange forum.

No, it isn't.
Its physics...
Yes, this should be on the StackOverFlow's Physics Blog...
@Sai Dutt
Why don't you google it?

Someone said that:
As technology advances, the size of bits in computers decrease. As these bits approach subatomic particular size, they begin to exhibit Quantum mechanics (these bits are appropriately named Qubits).
Imagine a computer searching through a four digit binary number. (E.g. 0000, 0001, 0010...1111). A normal computer would take 16 operations. However, a qubit can take the value of 0 or 1 or both, so you can simultaneously check all values of a digit at once, requiring only 4 operations. Hence, for an algorithm requiring N operations, a Quantum Computer would only need sqrt(N) operations, exponentially increasing the speed of a computer.
Also, you can increase the efficiency further. Due to something known as an Observer Principle, the value of a qubit is undefined until you observe it. Which is to say, it is in all states simultaneously. But due to something called Quantum Entangling, a qubit maybe be entangled to another. Which means, you can accurately predict the value of another qubit. For example, you know a qubit has a value of 0. If you know the other entangled qubit is the opposite of the first, then you know the qubit has a value of 1.
So far so good, but is a there a drawback? Imagine cracking a code, and searching through all the prime numbers. A normal computer would take years to crack it, but a Quantum Computer would take far less time (sqrt(N), remember?). If a company has confidential data, Quantum Computers can hack quickly. There is one way to avoid it; fight fire with fire. All countries could upgrade to Quantum Computers, but that would be very costly.
Google and other large companies have almost developed a commercially viable Quantum Computers. In conclusion, whatever the future of computing may be, Quantum Computers are definitely involved.
P.S. I may have gotten something wrong or incorrect. Please excuse me, I don't know a lot about Quantum Computers. 😅

Yes
It study's about relation of quark and gluon and colour charge of quarks. Quark are particle responsible for proton and neutron
