I bet you someday or somewhere may have heard of Quantum computer .But ever wondered what it is why companies like Google,Microsoft,IBM,NASA all are giving there all for research of quantum computing.Well in this this Article i am going to help you understand what is quantum computing.
What is quantum computing?
Quantum computing is the area of study focused on developing computer technology based on the principles of quantum theory, which explains the nature and behavior of energy and matter on the quantum (atomic and subatomic) level. Development of a quantum computer, if practical, would mark a leap forward in computing capability far greater than that from the abacus to a modern day supercomputer, with performance gains in the billion-fold realm and beyond. The quantum computer, following the laws of quantum physics, would gain enormous processing power through the ability to be in multiple states, and to perform tasks using all possible permutations simultaneously. Current centers of research in quantum computing include MIT, IBM, Oxford University, and the Los Alamos National Laboratory.
How Quantum computing work’s?
The computer’s we use today fall’s in category of conventional computer’s.Conventional computer’s can store and process data only in binary form that is either  or  known as BITS but at a given position there can only one value for a bit at a time .While quantum also stores and processes data in  and  form but they are known as Qubit.
Quantum computing is based on the concept of Qbits instead of bits.Qbits exploit one characteristic of quantum mechanics called superposition. Basically it means that a quantum system can be in a particular state which is contemporary in more than one state.So that states that for a certain data bits need time to process but qubits can process faster than bits because of its ability of being both values at same time.For example an electron which usually has spin “up” or “down” can be in a superposition of the two, hence being “up” and “down” at the same moment. (until the spin is measured).
Quantum computing makes computing calculation much easy and extremely faster due to its ability of taking all possible pattern of problem solved at same time while in conventional computer the computer have to try every single possible pattern of problem and process it all which takes hell lot of time and power.Quantum computers are extremely good at completing very hard calculations faster that classical computers. For example the factorization of very big prime numbers, a task which is closely related to cryptography and security of passwords.
So Quantum computing makes it easier to calculate large no. of problems and gives you the best result in much shorter time.Quantum computing makes use of the “Grover Operator” to sort out the right answer of the processed problem. Conventional may even take year’s to crack a problem but quantum computing can do it in minutes literally just minutes.

Benefits of Quantum computing:
- Quantum computers are extremely good at completing very hard calculations faster that classical computers.
- Quantum computers can predict answers due to shortcuts in the answering process.
This will benefit us with weather calculations, heavy mathematical calculations such as space travel, gravitational calculations and so on. It will also benefit us in the matter of understanding our world and space due to it’s ability to predict and calculate things that would normally take years in a matter of minutes.
Regarding the use of quantum computers we are still at the beginning of this new era of computing, hence there are for sure a lot of way to use this new technology that have yet to be discovered.Quantum Computing will not replace Conventional computing. It will augment and be used to solve or “crack” very complex algorithms.
