Quantum Computing: The Era of New Opportunities for Data Processing

Ever feel like taking a wild guess and trying to imagine what the world will look like if a computer can solve even the most complex problems faster than an eye blink?

Imagine a machine so powerful, which would crack the toughest of codes, simulate the functioning of the human brain, or help in discovering new drugs overnight.

This is not science fiction—this is the promise of quantum computing.

A revolutionary technology is going to change the way we process information, and it’s just around the corner.

But what exactly is quantum computing? How does it differ from our everyday computers? Let us plunge into the depths of this exciting new frontier.

What is Quantum Computing?

The first key to understanding quantum computing is going back to understand how traditional computers work. The computers that people are used to, like the one you might be reading this on, were built off the principles of classical physics.

They use something called “bits” to process information.

A bit can be either a 0 or a 1 and putting millions of them together can be used by the computer to calculate, execute software, and process data.

Quantum computers, on the other hand, are based on the principles of quantum mechanics a branch of physics concerned with the weird and mysterious way particles act and behave at an atomic and subatomic level. Unlike classical bits, quantum computers use “qubits.”

What Makes Qubits Special?

Qubits are special because they can be in more than one state at the same time. The qubit is different from the classical bit in that it’s not just a 0 or a 1, but it has this property called superposition that allows it to be 0 and 1 at the same time.

In this way, the quantum computer gains a very large information-carrying capability all at one time and provides enormous power for calculations of certain types.

But that is not all: qubits have yet another surprising property, called “entanglement.”

When two qubits—a pair—become entangled, the state of one is in some way directly connected to the state of the other, no matter how well separated they are. This lets quantum computers execute certain types of calculations many orders of magnitude faster than classical computers can.

How Does Quantum Computing Work?

So, how do quantum computers actually use qubits to perform calculations? Well, it is everything about quantum gates, so to say—the building blocks for quantum algorithms. These gates shuffle qubits in ways that none of the classical bits can be shuffled.

For instance, a quantum gate can put a qubit into superposition or entangle it with another qubit. The string of quantum gates constitutes a quantum circuit.

That one circuit does a calculation which, if done on a classical computer, will take thousands or millions of years.

Why is Quantum Computing Important?

You may be thinking, “Why should I care about quantum computing?” Well, the potential applications are out of this world. Following are some of the areas wherein quantum computing may create huge ripples:

• Cryptography: Quantum computers will break the codes protecting our data today. At the same time, it will be able to generate new, unbreakable codes. That will make our digital world safer.
• Drug Discovery: Quantum computers could simulate molecules and chemical reactions at an atomic level to accelerate the discovery of new medicines.
• AI Enhancement: AI may have the potential to become much more powerful by quantum computing, such that machines learn faster and make better decisions.
• Climate Modeling: Quantum computers could help us understand and predict climate change by analyzing vast amounts of environmental data.

Qubits are very sensitive and bound to lose their quantum state due to “decoherence” by interaction with the environment.

This makes it hard to keep the accuracy in quantum calculations. Also, quantum computers require low temperatures for proper functionality. This needs very complicated and expensive systems of cooling hence hard to build and maintain.

The Future of Quantum Computing

Despite these difficulties, enormous strides are being made by both researchers and companies at large around the world.

Companies such as IBM, Google, and Microsoft are investing strongly in quantum computing research.

Indeed, Google made headlines recently when it claimed to have achieved “quantum supremacy”—a milestone in which a quantum computer outperformed the fastest classical computer on a particular task.

We can only imagine more breakthroughs coming our way as scientists continue to venture deep into the possibilities offered by quantum computing. Though it’s still early days yet, the future indeed sounds very promising.
