QNTM.SW is trading at CHF 25.20, up 3.13%, as renewed enthusiasm across quantum-computing shares ahead of Quantum World Congress 2026, beginning September 23, appears linked to the move.

  • After the September 22 close, IonQ announced an industry-first real-time quantum error-correction decoder, sending its shares sharply higher in after-hours trading.
  • IonQ represents about 5.8% of the ETF; broader technology strength also supported sentiment.
