Quantum Computing Explained

Quantum Computing Explained

May 21, 2019

It is fascinating to think about the power in our pocket—today’s smartphones have the computing power of a military computer from 50 years ago that was the size of an entire room. However, even with the phenomenal strides we made in technology and classical computers since the onset of the computer revolution, there remain problems that classical computers just can’t solve. Many believe quantum computers are the answer.

The Limits of Classical Computers

Now that we have made the switching and memory units of computers, known as transistors, almost as small as an atom, we need to find an entirely new way of thinking about and building computers. Even though a classical computer helps us do many amazing things, “under the hood” it’s really just a calculator that uses a sequence of bits—values of 0 and 1 to represent two states (think on and off switch) to makes sense of and decisions about the data we input following a prearranged set of instructions. Quantum computers are not intended to replace classical computers, they are expected to be a different tool we will use to solve complex problems that are beyond the capabilities of a classical computer.

So what actually is Quantum Computing?

Let’s say we have a coin. Upon tossing it we will either have heads or tails. This how classical nano tech computers have been working so far. Bits. Zeroez and Ones. We have achieved quite a lot by this simple switching mechanism.

Now in quantum world things changes. We now posess the ability to make the coin stand and spin it. We bring in more quarter coins and spin them together. We achieve more innovative and powerful computing power. In technical terms we call them qBits.
qBits can hold enormous amount of data with low energy consumptions. qBits can be in a state of 0 or 1 and in both states at a time, giving them unprecedential processing power.

This processing power can be furthere utilised in critical applications. Thankfully, firms like Nasa, Google, Microsoft, BAARC etc, have been xtremely investing in the idea of quantum computers, because they’ve got a whole lot of data they’d like to tackle, so they’ve got some of the world’s best quantum scientists holed up trying to figure out how we clear the final hurdles.
Quamtum computing has already being used in various industries and sectors.

So is the future here?


With power comes great responsibilities. Technology has been both a boon and curse. It depends on the hands that wield them.
Quantum computing is far from becoming commercialized. They have been and will be used by the giants for the greater good.
