IonQ Breaks Ground in Quantum Networking and Compute with Synthetic Diamond Film Advancement.

IonQ and Element Six have developed high-quality, quantum-grade diamond films that can be made using standard semiconductor manufacturing techniques. This breakthrough is crucial for building large-scale quantum networks and clustered compute, as synthetic diamonds are a key component for quantum memory systems and photonic interconnects. The innovation will enable mass production of consistent, high-performance systems for commercial quantum networks.

Title: IonQ and Element Six Breakthrough in Quantum-Grade Diamond Films

IonQ (NYSE: IONQ), a leading quantum computing and networking company, has made a significant breakthrough in the development of quantum-grade diamond films. In collaboration with Element Six, a De Beers Group company specializing in synthetic diamond materials, IonQ has created high-quality diamond films that can be produced using standard semiconductor manufacturing techniques. This advancement is crucial for building large-scale quantum networks and clustered compute systems, as synthetic diamonds are key components for quantum memory systems and photonic interconnects.

The development of foundry-compatible, quantum-grade diamond films marks a pivotal move towards scalable, fault-tolerant quantum systems. This innovation allows IonQ to mass-produce consistent, high-performance systems designed for commercial quantum networks. The ability to integrate these diamond films into standard chipmaking processes supports scalable production of diamond-based devices such as quantum memories and sensors.

Niccolo de Masi, Chairman and CEO of IonQ, commented, "Foundry-compatible, quantum-grade diamond films change the game in photonic interconnects, compute processors, and quantum networking. This innovation will allow us to mass-produce consistent, high-performance systems designed for commercial quantum networks."

Siobhán Duffy, CEO at Element Six, added, "Synthetic diamond is one of the most promising platform materials for quantum technologies, with use-cases across the entire ecosystem, especially in sensing and networking. These synthetic diamond thin films will enable at-scale fabrication of high-performance devices."

The breakthrough overcomes the previous limitations of producing micro- and nano-structured devices, which were previously limited to bespoke, R&D-scale techniques. This new approach allows for the bonding of quantum-grade diamond films onto common substrates like silicon and silicon nitride, enabling heterogeneous integration and foundry compatibility.

IonQ’s advancements are part of its ongoing progress along the photonic interconnect roadmap, which includes the recent completion of the Lightsynq acquisition. The integration of Lightsynq’s photonic interconnect and quantum memory technologies will accelerate IonQ’s roadmap towards scalable, fault-tolerant quantum systems.
