IonQ has demonstrated a quantum link that connects two different types of qubits at more than 1,000 entanglement events per second. The achievement could help engineers build larger quantum computers by allowing separate systems to exchange quantum information more efficiently.

The demonstration links a trapped-ion qubit with a silicon-vacancy (SiV) qubit inside a solid-state memory. A photonic interconnect carries the quantum connection between them using light. IonQ says the result exceeds the previous record for trapped-ion systems by more than four times.
