Rigetti Computing's Quantum Ambitions Amidst Losses and Insider Selling

Rigetti Computing's stock has surged 19.9% despite reported widening losses, softer revenue, and insider selling. Speculation about increased US government support for quantum technology and rising institutional interest have contributed to its rise. The company continues to invest in developing larger multi-chip quantum systems, but its investment narrative relies on its ability to translate technical progress into real, paying use cases. The government angle changes sentiment, but raises stakes if support fails to materialize.
