IonQ hits 1,000 entanglements per second in quantum memory link

IonQ demonstrated a quantum link connecting a trapped-ion qubit with a silicon-vacancy qubit in solid-state memory via a photonic interconnect. The rate exceeds 1,000 entanglement events per second, more than four times the previous record for trapped-ion systems.

• Link exceeds 1,000 entanglement events per second
• Previous trapped-ion record beaten by more than 4x
• Connects a trapped-ion qubit with an SiV qubit in solid-state memory
• University of Maryland bought the first commercial system in April 2026
