Quantinuum vs. IonQ: Why One Major Wall Street Firm Says This Stock Is the Better Bet

Morgan Stanley upgraded Quantinuum to overweight and named it the top quantum computing stock pick, citing its lead in quantum error correction (Stage 7 vs IonQ's Stage 4) and execution. However, IonQ retains advantages in physical qubit performance and scalability through its microwave antenna technology and strategic acquisitions. Both companies are leading the quantum computing race, with the sector potentially reaching $100 billion by 2040.
