IONQ ~+10–12% — first real-time quantum error decoder on a single CPU; peers bid

IonQ (IONQ) ripped in extended hours Tue (~+12% AH) and held a double-digit bid into Wed premarket after saying it tested what it calls the industry’s first end-to-end real-time quantum error decoder running on a single commercial CPU. Company/desk wraps cite simulated stretch to ~408 logical qubits / >31.5M operations with very low overhead under typical noise assumptions. Quantum peers (RGTI, QBTS, INFQ) were bid ~+5–6% in the same premarket window per CNBC movers.

Scalper read: catalyst-driven speculative tape — mark open vs AH high and whether the decoder story holds once the headline fades. Don’t treat a one-day quantum basket as proof of commercialization timeline; size for gap risk.

Holding the IONQ decoder gap into Thu, or fading once the peer basket mean-reverts?
