Quantum stocks compared: IonQ (IONQ) vs Rigetti (RGTI) vs D-Wave (QBTS)
IonQ, Rigetti, and D-Wave all sell quantum computers, but they use different technologies and run businesses of very different sizes. IonQ reported $80.1 million of second-quarter revenue, nearly 10 times Rigetti and D-Wave combined.
IonQ (IONQ) jumps on a quantum error-correction claim and a first system for Nvidia's research center
IonQ shares jumped after the company said it built the first end-to-end real-time quantum error decoder on a single CPU, tested on simulated circuits of up to 408 logical qubits. IonQ also said its Superion 256 will be the first on-premises quantum computer at Nvidia's research center in 2027.

IBM has a $1 billion quantum foundry award. Where do IonQ, D-Wave and Rigetti get their chips?
Anderon, IBM's Albany quantum foundry, signed its final $1 billion CHIPS award on Wednesday and named no outside customer. D-Wave's Advantage2 prototype came from a SkyWater fab that IonQ bought in July, Rigetti runs its own fab in Fremont, and neither IonQ nor Quantum Computing Inc received an award.

The government is betting billions on quantum computing, but the payoff is years away
Washington is now a quantum-computing investor, having committed about $2 billion to nine companies and taken equity stakes back in May. But the technology will not pay off for years, and the pure-play stocks are already priced for a future that has not arrived. Here is the realistic picture.
