Rigetti Computing vs. Quantum Computing: Which is the Better Quantum Stock?

Rigetti Computing and Quantum Computing are two different ways to invest in the quantum computing market. Rigetti is an established producer of quantum chips, systems, and cloud software solutions, while Quantum Computing, or QCi, develops experimental chips. Over the past 12 months, Rigetti's stock rallied nearly 60% compared to QCi's 3% rise. Rigetti is a "full stack" quantum computing company that manufactures its own QPUs, installs them in its own systems, and hosts a cloud-based quantum-computing-as-a-service platform. QCi, on the other hand, develops photonic chips that process data by beaming light through chips and fibers.
