It’s fascinating to think about the power we have in our hand. Today, the tiny transistors in the smartwatch, smartphones are capable of more advanced computing than scientists of the 1950s could’ve ever dreamed. However, even with the phenomenal advancements we made in technology, there remain some problems that classical computers just can’t solve. And many believe quantum computing/computers are the answer.

QC (Quantum Computing) – Why & How?

A normal computer chip uses bits. These are like tiny switches, that can either be zero (off position) or in one (on position). For most of the operations this works good enough, but it doesn’t reflect the way the universe actually works. In real world, things aren’t just on or off instead they’re in flux and in fields. And even our best supercomputers aren’t very good at dealing with uncertainty.

However, QC (Quantum Computers) can leverage the quantum mechanical phenomena to manipulate information. Instead of bits, quantum computers use qubits. Rather than just being 0 or 1, qubits can also be in what’s called ‘superposition’ – where they’re both 0 and 1 at the same time, or anywhere on a spectrum in-between. This means that a computer using qubits can store an enormous amount of information and uses less energy. For example, if we ask a normal computer to figure its way out of a maze, it will try every single path in turn, ruling them all out individually until it finds the right one. A quantum computer can go down every path of the maze at once. It can hold uncertainty in its head, figuratively speaking!

By entering into this quantum area of computing where the classical laws of physics no longer apply, we are able to create processors that are significantly faster (a million times more) than the ones we use today. Sounds fantastic, but the challenge is that quantum computing is also incredibly complex.

How QC will change our world:

With QC , we are venturing into an entirely new realm of physics and there will be solutions and uses for many things which we have not even conceptualized yet. But when you consider how much classical computers revolutionized our world with a relatively simple use of bits and two options of 0 or 1, one can imagine the extraordinary possibilities when the processing power of qubits that can perform millions of calculations at the same moment.

However, what we do know is that it will be game-changing for every industry and will have a huge impact in the way we do business, design and develop new medicine, space exploration, logistics optimization, financial modeling, safeguard our data, predict weather events and climate changes, etc.

It’s no coincidence that some of the world’s most influential companies like IBM, Google, etc and the world’s governments are paying attention/investing heavily in QC technologies. So are the startups in Silicon Valley working on QC algorithms. They are expecting QC to change our world because it will allow us to solve problems and experience efficiencies that aren’t possible today.

In my upcoming post, I will dig deeper into how QC will potentially reshape our future…
