IONQ Marks Significant Milestone Advancing Ion-Ion Entanglement

IonQ, (IONQ) a leading player in the quantum computing industry, has reached a major milestone on its path to scaling quantum systems by demonstrating remote ion-ion entanglement. Building on the ion-photon entanglement breakthrough announced in February, this September milestone marks the second of four key steps needed to develop photonic interconnects, a crucial component of IonQ’s strategy for quantum networking and system scalability.

“With these recent advancements, our focus now shifts to the next phase – transferring ion-ion entanglement to the QPU. We are dedicated to pushing the boundaries of this technology and advancing photonic interconnects to a level where they can be integrated into commercially available quantum computers,” said Peter Chapman, President & CEO of IonQ.

In this latest achievement, IonQ’s R&D team successfully entangled two trapped ion qubits from separate wells using photons and is a critical part of establishing quantum communication links, key to scaling quantum systems. The IonQ team achieved remote entanglement by developing a system to collect photons from two trap wells and routing them to a single detection hub.  No company has previously demonstrated this technology at a stage where it can be integrated into enterprise-grade quantum computers.

IonQ continues to make strides toward modular quantum computing systems through its focus on performance, scalability, and enterprise-grade capabilities.
