IonQ's Quantum Offerings

IonQ has developed a range of quantum computing systems, including the Aria, Forte, and Forte Enterprise systems. The company primarily targets government clients and universities, while also providing cloud-based quantum computing services. IonQ's innovative "trapped ion" technology aims to miniaturize quantum processing units (QPUs) from several feet to just inches, potentially leading to more affordable and powerful systems in the future 1

Rigetti's Full-Stack Approach

Rigetti positions itself as a "full-stack" quantum computing company, designing and manufacturing its own QPUs while allowing developers to create custom quantum algorithms on its Forest cloud platform. The company has made significant strides with two major product launches:

1. The Novera QPU: A 9-qubit commercial model priced at $900,000, which has attracted orders from major government and research entities 1

Financial Performance and Market Outlook

Both companies went public through special purpose acquisition companies (SPACs) but fell short of their pre-merger revenue targets:

• IonQ reported $22 million in revenue for 2023, below its $34 million goal 1

Investment Considerations

While both companies show promise, they face challenges:

1. Profitability: Both are projected to remain unprofitable for the foreseeable future 2
