## Resource

The groundbreaking Pinnacle Architecture paper has sent shockwaves through the quantum computing industry by demonstrating that RSA-2048 encryption could potentially be cracked with just 100,000 physical qubits. This is a massive order-of-magnitude reduction from previous estimates that once reached into the millions. Join host Konstantinos Karagiannis as he sits down with Felix Thomsen and Paul Webster from Iceberg Quantum as they explain the techniques in the paper and its serious potential ramifications. By leveraging high-efficiency LDPC codes and a novel modular architecture, the team explains how they’ve bridged the gap between theoretical quantum error correction and practical hardware implementation, effectively accelerating the timeline toward Q-Day. More than one quantum computing hardware roadmap has us reaching 100,000 physical qubits before 2030! And there’s no reason to believe future work couldn’t lower the qubit requirements even more. Beyond the security implications, the architecture is also a blueprint for the first generation of utility-scale quantum systems. Thomsen and Webster detail how their modular design—featuring dedicated processing units, magic engines, and shared memory—can be optimized for “slow” hardware like trapped ions or applied to life-changing scientific breakthroughs in quantum chemistry and material science. Whether you are a cryptographer bracing for the post-quantum transition or a scientist eager to see the first practical applications of fault-tolerant quantum computing, you’ll need to understand this paper’s potential impact.
