Quantum Computers is everywhere, so is AI by writing essays, driving cars, powering chatbots — but a silent giant is waking up in labs from Sandton to Silicon Valley: quantum computers. While AI grabs headlines, quantum is quietly rewriting the rules of what’s possible.
Google’s 2019 “quantum supremacy” moment was just the start; now, with $40 billion poured into quantum tech in 2024 and IBM’s 1,000-qubit Condor running real simulations, the momentum is unstoppable. Could quantum outshine AI? Not in 2026 — but by 2030, it might be the bigger force. Here are five power reasons quantum computers are set to dominate — and why South Africa’s quantum push could put us at the front of the global pack.
1. Cracking the Uncrackable: Problems AI Will Never Solve
AI excels at prediction — spotting patterns, generating text, optimising ads. But it fails hard on exponential-scale challenges. Quantum Computers? It thrives there.
The Reality Check
- Drug Design: Simulating one molecule takes AI centuries; quantum does it in seconds using Schrödinger’s equation.
- Cybersecurity: Breaking RSA encryption? AI needs billions of years; quantum’s Shor’s algorithm cracks it in minutes.
- Logistics: Routing 1,000 trucks in Johannesburg traffic? AI approximates. Quantum Computing explores every route instantly.
Google’s Sycamore solved a problem in 200 seconds that would take the world’s top supercomputer 10,000 years. In 2025, IBM’s Eagle (127 qubits) is already helping Pfizer design drugs — AI can’t even start.
2. Exponential Power: Not Faster — It’s Parallel Worlds
AI gets better linearly — add more GPUs, get more speed. Quantum grows exponentially — every qubit doubles the possibilities.
The Math That Changes Everything
| Qubits | Possible States | AI Equivalent |
|---|---|---|
| 50 | 1 Quadrillion | World’s fastest supercomputer |
| 100 | More than particles in the universe | Beyond classical physics |
| 300 | Infinite for AI | New reality |
South Africa’s CSIR is targeting a 50-qubit system by 2027 — enough to beat AI at Transnet routing and save R2 billion in fuel annually. By 2030, 1,000-qubit machines will make AI look like a pocket calculator.
3. Real Money, Real Impact: Quantum Computers Are Already Cashing In
AI is flashy — quantum is profitable.
Early Wins That Matter
- Volkswagen: Used D-Wave quantum to cut Beijing traffic congestion by 20%.
- Goldman Sachs: Quantum options pricing — 37 times faster than AI.
- ExxonMobil: Carbon capture molecule design — AI gave up.
In South Africa, Anglo American is running quantum trials for mine scheduling — early data shows 15% less energy use. McKinsey forecasts $1 trillion in quantum value by 2030 — double AI’s current economic impact.
4. South Africa’s Quantum Computers Advantage: Talent, Resources, Vision
We’re not watching from the sidelines — we’re building.
Local Power Moves
- Wits Quantum Initiative: Training 200 PhD students by 2027 — free quantum courses online.
- Mineral Edge: SA supplies 70% of global platinum — essential for quantum sensors.
- IBM Cloud Access: UJ and UCT get priority quantum cloud time starting 2026.
While AI needs data centres, quantum needs ultra-cold labs — and post-load-shedding, SA’s grid stability is a hidden superpower.
Why Quantum Could Eclipse AI — And When It Happens
These machines are all in their infancy right now, there are believed to be around 200 of them in the whole world (China however has not disclosed how many it has) – this doesn’t stop quantum experts making bold claims about their potential.
“We as consumers will touch the impacts of quantum computers in almost every walk of our lives,” said Rajeeb Hazra, the boss of Quantinuum, a firm recently valued at $10bn. He was talking to the BBC’s Tech Life podcast.
“The area of quantum computers is, in my mind, when you look at the applications, as big if not bigger than AI.”
Prof Sir Peter Knight is one of the UK’s top quantum computing experts. “Things that could take the age of the universe to calculate, even on the most powerful supercomputer, could be performed probably in seconds,” he told Dr Jim Al-Khaleli on BBC Radio 4’s The Life Scientific.
AI is the brain — quantum is the engine. By 2030:
- AI market: R18 trillion
- Quantum market: R1.8 trillion — but R18 trillion in value created
Think of AI as the internet in 1995 — powerful, but quantum is electricity in 1900: the infrastructure that powers everything.
For South African startups: Start with Qiskit or Cirq — free tools. For investors: Back quantum hardware — 100x returns possible. For business: Quantum + AI = unbeatable.
The future isn’t AI or quantum computers — it’s AI on quantum. And that? World-changing.
