IONQ Inc is trading 5.9% up at $61.28 in pre-market, rebounding from a recent pullback as Horizon Quantum announced plans to deploy IonQ’s next-generation 256-qubit system in Dublin.

  • The deployment of the 256-qubit trapped-ion system represents a key commercial win, driving fresh investor enthusiasm for the quantum computing firm.
  • The stock is further supported by a broader risk-on rally in the tech sector, with the Nasdaq tracking higher on easing geopolitical tensions and a decline in energy prices.
