What if the real breakthrough in quantum computing is not just better qubits, but a better way to use them?

In this episode, I explore why architecture may be one of the most overlooked layers in quantum computing with Magdalena Hauser and Wolfgang Lechner of ParityQC. Their latest result, implementing a 52-qubit Quantum Fourier Transform on an IBM Quantum Heron processor, suggests that progress may not only come from hardware improvements, but also from smarter architecture and compilation.

This episode is for investors, founders, and anyone trying to understand where value may build across the quantum stack. If ParityQC is right, the winners in quantum may not only be the companies building the machines. They may also be the companies that make those machines more useful, more scalable, and more efficient.

That is what makes this conversation so interesting. It shifts the question from who has the best hardware to who has the best architecture for turning hardware into real performance.

💡 In this episode, we cover:

• Why ParityQC believes architecture is a core layer of value in quantum computing

• Why the Quantum Fourier Transform is such an important benchmark

• How ParityQC and IBM reached a 52-qubit QFT result

• Why this result is about more than hardware alone

• How architecture and compilation can improve real quantum performance

• Why ParityQC’s approach is designed to work across multiple hardware platforms

• Why removing swaps matters in quantum computing

• Why investors may need to look beyond hardware to understand where value will accrue
