Summary
Quantum computing is entering a new phase where scale depends on how qubits are built and integrated, not only on counts. In a discussion with QuantWare CEO Matt Rijlaarsdam, the Quantum Open Architecture model takes center stage. Modular, plug and play components could let universities and companies assemble machines from processors, control electronics, and cryogenics sourced from different vendors, similar to how the PC industry evolved.
This shift promises faster iteration, lower barriers to entry, and a broader supplier ecosystem. Instead of closed black boxes or vertically integrated stacks, specialization could unlock performance gains and accelerate experimentation. QuantWare, a Dutch startup supplying superconducting processors, is one example, but the implications extend across the industry.
For the quantum security community, modularity brings both opportunity and responsibility. Clear interfaces enable better assurance, but a larger supply chain and more interconnects expand the attack surface, from firmware and calibration integrity to side channel risks across modules. Progress will hinge on shared standards, component provenance, certification profiles, secure update and key management practices that mirror mature classical supply chains while anticipating quantum specific threats.
