What it builds

IonQ uses trapped ions as qubits in its computing systems. Its technology explanation describes control using lasers and connected qubits. Performance comparisons still need a workload, accuracy target and total execution cost.

Business and quantum exposure

The 2025 results identify NYSE: IONQ and USD 130.0 million in annual revenue. The company's broader portfolio means total revenue should not automatically be labeled quantum-computing revenue alone. Inspect acquisition effects and segment disclosures. After this period, IonQ completed its acquisition of U.S. semiconductor foundry SkyWater Technology on July 31, 2026, and on October 12, 2026 announced an agreement, signed October 9, to acquire Zero Trust security company Elisity in an all-stock deal valued at up to $1.3 billion, expected to close in the fourth quarter of 2026. Revenue reported after these dates can include non-quantum businesses.

interpretation

Research questions and risks

Operating cash use and equity financing are material research questions. Check repeat business, technical performance and integration costs. A large cash balance does not establish operating profitability or guarantee a development timeline.
