It’s an exciting time in quantum computing. It can be difficult to see through the noise amid all the headlines and bold claims, but progress is real and accelerating. For the first time, multiple hardware modalities have credible paths forward, with a realistic shot at reaching tens to hundreds of thousands of physical qubits within the next few years. 

Our aim with Iceberg Quantum is to be the architecture company: to help accelerate the transition to, and ultimately power, the fault-tolerant era of quantum computing by defining how this hardware computes.

Our approach is to build the world’s best fault-tolerance research lab, and to partner closely with leading hardware companies to work toward implementation. 

Recognising that we’re still early in our journey, today we’re excited to announce a few milestones on our progress.

We’ve released Pinnacle, our first full fault-tolerant quantum computing architecture. It validates our core thesis: that architectures can be an order of magnitude better, requiring 10x fewer physical qubits. To demonstrate this, we compile a canonical benchmark application—factoring 2048-bit RSA integers—long thought to require millions of physical qubits, and show it could instead be achieved with fewer than one hundred thousand. We believe this represents a meaningful step toward utility-scale quantum computing, and warrants a reassessment of assumptions around when cryptographically relevant machines may be built.

We’ve formed an exceptional initial team and are excited to expand it further, with several people joining shortly as we grow beyond Sydney, opening our first overseas office in Berlin and expanding our team in the US. We’re bringing together some of the best people in the world working on fault tolerance, who have authored many of the most significant advances in the field in recent years.

Finally, we’ve raised $6 million in Seed funding from LocalGlobe, Blackbird, and DCVC. The new funding will help us scale our work across research and design partnerships with leading hardware companies.

We’re incredibly excited about the future of quantum computing, as fault tolerance, which once felt so distant, is coming into focus. If you are too, perhaps you should consider joining us.
