IonQ Demonstrates 1,000 Entanglement Events per Second in Quantum Interconnect

Insider Brief

• IonQ has demonstrated entanglement rates exceeding 1,000 events per second between a trapped-ion qubit and a silicon-vacancy solid-state quantum memory using a photonic interconnect.
• The company says the result is more than four times faster than the previous trapped-ion interconnect record and could support distributed quantum computing.
• The work supports IonQ’s participation in DARPA’s HARQ program and builds on commercial quantum networking system sales to the University of Maryland and South Korea’s SDT.

PRESS RELEASE — IonQ (NYSE: IONQ), the world’s leading full-stack quantum platform and foundry, today announced the achievement of entanglement rates above 1,000 per second (1 kHz) between a trapped ion qubit and a solid-state memory, through a photonic interconnect. Entanglement is the quantum connection that lets separate systems work together, and it is the essential ingredient for networking quantum computers. While the trapped ion qubit sets the standard for qubit coherence, the solid-state quantum memory has unmatched efficiency coupling to light. Their juxtaposition is the best of both worlds, demonstrating the fastest quantum interconnect rate between qubits of any platform.
