Briefings

IonQ announced a breakthrough entanglement rate exceeding 1,000 events per second between a trapped-ion qubit and a silicon-vacancy solid-state memory via photonic interconnects. This achievement surpasses the previous record by more than four times and supports participation in DARPA's HARQ program. The demonstration builds on prior commercial sales to the University of Maryland and SDT in South Korea, with technical details available in an arXiv preprint.

Key points

• IonQ achieved entanglement rates above 1,000 events per second (1 kHz) using a trapped-ion qubit and a silicon-vacancy (SiV) solid-state memory platform connected via photonic interconnects.
• The new rate exceeds the previous record by more than four times, held by IonQ co-founder Chris Monroe's research group at Duke University, which previously set the benchmark for trapped-ion interconnects.

Context and limitations

The evidence is limited to a single press release and one technical paper; no other independent verification or long-term operational data is provided.
