IonQ and SDT Ink Multi-Year Quantum Partnership for South Korea

B. Riley Securities is maintaining bullish ratings on IonQ, D-Wave Quantum and Rigetti Computing ahead of Quantum World Congress, betting that a shift in government policy from pure research toward commercialization could open a more meaningful revenue path for the quantum-computing sector. The firm kept Buy ratings with price targets of $100 for IonQ, $40 for D-Wave and $35 for Rigetti. Analyst Craig Ellis pointed to the Department of Energy's From Lab to Market session at the September 23-25 conference as a sign that federal policy may increasingly focus on moving quantum technologies into commercial applications. The event will also feature a two-hour National Quantum Updates session with more than 10 governments, participation from the White House Office of Science and Technology Policy, and back-to-back keynotes from Microsoft and IBM. B. Riley's thesis is sector-wide, but the report provides no fresh revenue forecasts, cash-flow estimates, technical milestones or new valuation work behind the three price targets, leaving the stocks dependent on long-term expectations rather than near-term financial evidence.

Rigetti Computing said in its latest technology update that the biggest challenge in its quantum roadmap is no longer adding more qubits but improving the performance of its flagship 108-qubit Cepheus system. During the second quarter of 2026 earnings call, management acknowledged that coherence time has become the primary bottleneck limiting two-qubit gate fidelity, even as Cepheus-1-108Q stands among only three generally available gate-based quantum computers with more than 100 qubits. The system currently operates with coherence times of roughly 25-30 microseconds, a level that constrains the reliability of quantum operations. Rigetti is directing engineering efforts toward chip redesigns, fabrication process improvements and new materials, including tantalum-capped superconducting contacts, and management expects these initiatives to gradually double or even triple coherence times over the next several years. In peer updates, Quantum Computing Inc. signed a three-year Framework Agreement with Hamad Bin Khalifa University in Qatar covering quantum computing, sensing and communications, while IonQ secured an $8.18 million commercial agreement with Congruity360 to integrate quantum-safe networking into its enterprise data management platform.

IonQ reported second-quarter 2026 sales of $80.1 million, up 287% from a year earlier, with part of that growth coming from a series of acquisitions and the rest from organic quantum revenue. Management estimates organic revenue will double for the full calendar year 2026, helping total sales, including acquisitions and organic growth, reach an estimated $455 million this year, a 60% increase over the company's previous guidance, though the raised full-year revenue guidance came just after IonQ completed its purchase of the chip foundry business SkyWater Technology on July 31. The company's non-GAAP adjusted EBITDA loss widened to $120.3 million in the second quarter from $36.5 million a year earlier, driven by expensive research and development costs and rising sales and general administrative costs, and that loss far exceeded quarterly revenue. IonQ holds cash and cash equivalents of $3 billion, giving it substantial runway despite being unprofitable, while its stock trades at a price-to-sales ratio of 51, well above the tech sector average of about 7, even after a roughly 42% share price decline over the past year.
