On the 23rd of Sept. 2024, CNN’s Anna Stewart explores how the future of Quantum Computing could change our world.
Imagine a world where we can simulate complex molecules to create life-saving drugs in a fraction of the time it takes today. Think of a future where we can optimize global supply chains to eliminate waste and reduce our carbon footprint. Envision a reality where we can crack the most challenging problems in physics, potentially unlocking the secrets of the universe itself. This isn’t science fiction, my friends. This is the promise of quantum computing, and it’s closer to reality than you might think.
Let me take you on a journey through the fascinating world of quantum computing, where the rules of classical physics no longer apply, and the impossible becomes possible.

The Birth of a Quantum Dream
Let’s delve into a bit of history. It all began in the early 1980s when a brilliant physicist named Richard Feynman had a wild idea. He proposed that we could harness the strange and counterintuitive properties of quantum mechanics to create a new kind of computer – one that could solve problems that would take our most powerful classical computers millennia to crack.
For decades, this remained just a tantalizing and a fantasizing dream. But in recent years, something incredible has happened. Thanks to relentless innovation and billions of dollars in investment, we’re now on the cusp of making Feynman’s vision a reality.
Qubits: The Building Blocks of Quantum Computing Power
At the heart of this quantum revolution are qubits – the quantum equivalent of classical bits. But here’s where things get weird and wonderful. Unlike classical bits, which can only be in a state of 0 or 1, qubits can exist in a superposition of both states simultaneously, sounds amazing right? It’s like having a coin that’s both heads and tails at the same time!
This mind-bending property allows quantum computers to perform multiple calculations at once, giving them the potential to solve complex problems at speeds that would make even our most advanced supercomputers look like abacuses in comparison.
The Quantum Race is On
The excitement around quantum computing is palpable. Tech giants like IBM, Google, and Microsoft are pouring resources into developing quantum hardware and software. Startups are sprouting up like quantum mushrooms, each vying to be the one to achieve “quantum supremacy” – the point at which a quantum computer can solve a problem that no classical computer can solve in any feasible amount of time.
In 2019, Google claimed to have reached this milestone, performing a calculation in 200 seconds that would have taken the world’s most powerful supercomputer 10,000 years. While there’s debate about the practical significance of this achievement, it’s clear that we’re making rapid progress.
The Promise and the Perils
The potential applications of quantum computing are mind-boggling. From revolutionizing drug discovery to optimizing financial portfolios, from enhancing artificial intelligence to simulating complex chemical reactions, quantum computers could be the key to solving some of humanity’s most pressing challenges.
But with great power comes great responsibility. The same quantum computers that could crack complex scientific problems could also break the encryption that keeps our digital world secure. This has led to a race to develop “quantum-safe” cryptography before quantum computers become powerful enough to pose a threat.
The Road Ahead
While we’ve made incredible strides, we’re still in the early days of the quantum computing revolution. Challenges remain, particularly in scaling up quantum systems and reducing error rates. But the momentum is undeniable, and the future is bright.
As we stand on the brink of this quantum leap, one thing is clear: the world as we know it is about to change. Quantum computing isn’t just about faster processors or more powerful machines. It’s about unlocking new realms of possibility, pushing the boundaries of what we thought was possible, and reimagining our relationship with the fundamental fabric of reality itself.
So, buckle up, folks. The quantum revolution is coming, and it’s going to be one wild ride. Are you ready to quantum leap into the future?
