# Understanding The Fundamentals Of Quantum Computing

Computer technology has evolved a lot in recent years. We’ve seen computers get smaller and more powerful faster and faster, which has led to a lot of new developments.

But we’re getting closer and closer to the physical limitations of computer parts, so we need to come up with new ways to make things better in certain areas. And quantum computing could be the answer.

## What is Quantum Computing?

What is a quantum computer? A quantum computer is a computer that uses some of the special qualities of quantum physics to figure out how to solve problems that would be too hard for ordinary computers or even supercomputers. Quantum computing is all about creating new ways to use the way energy and matter work at the atomic level.

We use the term “quantum” to talk about how the rules of physics apply to things like atoms, electrons, and elementary particles. The laws of physics at this tiny level are different from what we see in our everyday lives.

Quantum computing is still in its early stages and has only been around for a few years. In 2019, IBM introduced the world’s first commercial circuit-based quantum computer. In 2021, Google researchers reported that their quantum computer is performing at a higher level than supercomputers do.

## How Does Quantum Computing Work?

Quantum computing is complicated and hard for people who don’t know much about it to get a handle on. It’s still possible to understand some of the basics of quantum computers, so you can get a basic idea of how they work.

If you want to understand how quantum computers work, there are some basic ideas you need to know. We’ve briefly explained them below.

### Qubits

In our open-step exploration of qubits, we’ll be looking at how traditional computers are based on bits. These bits are the fundamental bits of data used in computing, where you can measure two different configurations. You can think of them as being either on or off, going up or going down, or, since they’re written in binary, either 0 or 1.

When it comes to quantum computing, the way these computers work is made up of quantum bits, or qubits. These quantum bits can be constructed from two-state quantum mechanical systems. You can measure how much of an electron’s spin is up, how much of it is down, or how much of a single light ray is polarized vertically or horizontally.

### Superposition

Unlike regular bits, which can either be 0 or 1, qubits can be either 0 or 1 or a combination of both. This is called superposition, which means all possible combinations of data can exist all at once.

When qubits are used together, they can store all sorts of different data sets at once, which makes it much simpler to represent complicated issues than with traditional computing.

### Entanglement

Another important factor in quantum computing is entanglement, also known as the quantum effect. It links two qubits together. So, when you have two or more entangled qubits, anything that changes one qubit affects the others.

This is the foundation of quantum computing algorithms, which make it possible to solve complicated problems much faster than ever before.

## Advantages Of Quantum Computing

**They’re fast**: In the end, quantum computers will be able to offer a level of computing power that we’ve never seen before. For instance, in 2019, Google said that it could do a calculation in just 200 seconds, which would take a supercomputer 10,000+ years to do.

**They can solve complex problems:** The more complicated the problem, the more difficult it is to solve, even for supercomputers. When a traditional computer doesn’t work, it’s usually because it’s complicated and there are lots of different things going on. But thanks to the ideas of entanglement and superposition, quantum computers can handle all these things and figure out how to solve them.

**They can run complex simulations:** Thanks to the speed and complexity of quantum computing, it’s possible that a quantum computer could be used to simulate all kinds of complex systems, which could help us figure out some of life’s biggest secrets.

## Disadvantages Of Quantum Computing

**They’re difficult to build: **A quantum computer, like IBM’s Quantum System One, needs a certain set of conditions to work. They need special parts, huge air conditioning systems, and pricey tech to work even on the simplest of tasks.

**They’re prone to errors: **Because of how quantum mechanics works and how qubits work, things in the environment can quickly cause mistakes and cause qubits to lose their state. These mistakes increase as they get more complex, so you need a way to fix them so they can be used to their full potential.

**They’re only suitable for specific tasks:** Let’s take a look at how quantum computers could be a game-changer in certain areas. However, because of how they operate, it’s not expected that they’ll be helpful in every aspect of computing.

## What Is Quantum Computing Used For?

Below, we’ve listed some of the current and potential uses for quantum computing.

**Molecular modeling:** Even with the best supercomputers out there, it’s still not easy to make accurate comparisons between atoms and molecules. Quantum computing can be used to simulate quantum physics, which could open up new ways of understanding things like how batteries work or how proteins work together, which could have a huge impact on energy storage and medicine in general.

**Database searching: **The way quantum computers solve problems means they can store and search through huge amounts of data much faster than conventional computers.

**Cryptography:** A quantum computer that runs at full power could be able to crack most of the current encryption systems, which could be a big problem for cyber security.

**Weather forecasting: **In meteorology, you need a ton of data and lots of different factors to make predictions. Even the most powerful supercomputers can’t accurately predict the weather. Using quantum computing, we could be able to increase the complexity of predicting the weather.

## How To Learn Quantum Computing

If you’re interested in exploring the world of quantum computing or thinking about getting into the field, there are a few skills you can pick up along the way. Below, we’ve listed a few areas where you might want to brush up on your knowledge.

**Mathematics: **Having a good grasp of math is helpful when it comes to quantum computing. Algorithms and knowledge of topics like data analytics are usually at the top of the game.

**Physics:** We’ve already talked about how quantum physics is the basis for quantum computing. If you want to get into the tech world, understanding the connection between physics and tech can be helpful.

**Programming:** Another important skill is being able to write and comprehend code. Python is one of the most important programming languages for quantum computing, and it’s the foundation of Qiskit, the software development kit that’s widely used in the field.

These are the top skills you need to know if you want to work in quantum computing. If you’re curious about how these amazing machines work, there are lots of open-source tools and websites that can help you figure it out.
