IonQ just dropped two back-to-back announcements that sent its stock surging while the broader quantum ETF slipped, and the reason one company is pulling so far away from the pack reveals something important about where the real quantum race is…This post may contain links from our sponsors and affiliates, and Flywheel Publishing may receive compensation for actions taken through them. Shares of IonQ (NYSE:IONQ | IONQ Price Prediction) are rallying in Wednesday morning trading on two company announcements landing back to back: an error-decoder breakthrough disclosed after Tuesday’s close, and a premarket disclosure that IonQ’s Superion 256 system will be the first on-premise quantum computing deployment at NVIDIA‘s (NASDAQ:NVDA) Accelerated Quantum Research Center.
