IonQ should prioritize acquiring Riverlane, the quantum error correction software company, as their quantum error correction capabilities would transform IonQ's trapped ion systems from NISQ devices into fault-tolerant quantum computers capable of commercial applications requiring millions of operations. The AHP Advisory Board reached 36.6% weighted consensus favoring Riverlane due to immediate value multiplication potential and minimal integration complexity, with software-hardware synergies enabling rapid deployment across IonQ's existing quantum computing infrastructure. Alpine Quantum Technologies emerged as the secondary acquisition target with 32.1% board support, providing European market expansion and complementary trapped ion innovations that would strengthen IonQ's core technology competencies while accessing EU quantum sovereignty initiatives. The board unanimously rejected larger acquisitions like Xanadu due to integration complexity and technology conflicts, instead favoring focused acquisitions that enhance rather than diversify IonQ's trapped ion quantum computing leadership position. Fat Sam's Law optimization revealed that strategic acquisitions in quantum error correction and geographical expansion provide superior risk-adjusted returns compared to technology diversification strategies, positioning IonQ for fault-tolerant quantum computing leadership through targeted capability enhancement rather than platform fragmentation.
