Iceberg Quantum Just Shrank a 20-Million Qubit Supercomputer
Iceberg Quantum has unveiled the Pinnacle architecture, a fault-tolerant quantum computing design that reduces the physical qubit requirement to break RSA-2048 encryption from roughly 20 million (or 1 million under recent Google estimates) to fewer than 100,000. This order-of-magnitude reduction is achieved by replacing traditional surface codes with quantum low-density parity-check (QLDPC) codes, which significantly lower error-correction overhead. While the claims are based on numerical simulations and …
