Story summary

IonQ and Rigetti Computing face profitability and accuracy challenges.
IonQ is valued at $17 billion and achieves 99.99% two-qubit gate fidelity with trapped-ion qubits, trading speed for precision.
Rigetti has a $7.7 billion market cap and pursues a 108-qubit system with fast gates but 99% accuracy.
Both are investing heavily in research and development (R&D) and posting significant net losses, so investors should view the sector as speculative and volatile.
