Here’s why quantum computing stocks IonQ, RGTI, QBTS, INFQ are rising
Quantum computing stocks IonQ, Rigetti Computing (RGTI), D-Wave Quantum (QBTS), and Infleqtion (INFQ) are rising after IonQ announced a breakthrough in fault-tolerant computing. IonQ demonstrated an end-to-end real-time quantum error decoder running on a standard CPU, a milestone for scalable, commercial fault-tolerant systems. The company's revenue is expected to grow 250% this year to $455 million, with similar growth projected for peers.
