What Is a Fault-Tolerant Quantum Computer?
A fault-tolerant quantum computer is one that can process quantum calculations without errors. Unlike conventional computers that use binary bits (0s and 1s), quantum computers use qubits that exist in multiple states at once.
But there’s a challenge—qubits are fragile and easily disturbed by their surroundings. This leads to errors in calculations, making quantum computers unreliable. A fault-tolerant system solves this by correcting errors in real-time, ensuring stable and accurate computations.
If PsiQuantum succeeds, its computer could revolutionize industries by solving problems that traditional computers cannot.

Why Is Australia Investing $940M?
Australia is betting big on quantum technology, aiming to become a global leader. The government’s $940 million funding includes equity and debt to support PsiQuantum’s research. Additionally, Queensland has pledged $275 million, showing strong local commitment.
The Brisbane facility will serve as a key hub for quantum computing development, attracting top scientists and engineers. This investment could position Australia at the forefront of the global quantum race, a market projected to be worth $1 trillion by 2035.

PsiQuantum’s Unique Approach
PsiQuantum is different from other quantum computing companies. While rivals like Google, IBM, and Microsoft use superconducting qubits, PsiQuantum is pioneering photonic quantum computing.
| Company | Quantum Technology | Approach |
|---|---|---|
| PsiQuantum | Photonic quantum computing | Uses photons (light particles) instead of electrical currents. |
| Superconducting qubits | Requires extreme cooling to near absolute zero. | |
| IBM | Superconducting qubits | Focuses on error correction in cryogenic environments. |
| Microsoft | Topological qubits | Still in early research phases. |
PsiQuantum’s photonic chips are built using standard semiconductor processes, making mass production easier. The company manufactures its chips at GlobalFoundries in New York, proving its ability to scale.
Will the Project Succeed?
PsiQuantum admits that the technology doesn’t work yet, but that is normal in quantum computing. All companies in this field are still developing reliable, large-scale quantum systems.
By 2027, PsiQuantum aims to build a system with millions of qubits—a key milestone for quantum computers to outperform classical machines. If successful, this will be a game-changer for industries like:
- Pharmaceuticals: Simulating molecules for drug discovery.
- Energy: Designing better batteries and solar materials.
- AI & Machine Learning: Enhancing computing power for complex models.
- Finance: Optimizing large-scale financial transactions.
- Climate Science: Improving weather prediction models.

The Global Quantum Race
Australia is not alone in chasing quantum supremacy. The US, China, and Europe are all investing billions in quantum technology.
Recently, Google, Microsoft, and Amazon unveiled new quantum computing advancements. Nvidia also announced plans to establish a quantum research center in Boston.
PsiQuantum’s Brisbane project is a bold step forward in this competitive race. If the company achieves its fault-tolerant quantum computing goal, Australia could become a global leader in quantum technology.
