IonQ Inc. (NYSE:IONQ) is one of the worst AI stocks to invest in according to financial media. On September 4, IonQ announced a technological breakthrough in collaboration with Element Six, which is a De Beers Group company that specializes in synthetic diamond materials. They have successfully developed high-quality, quantum-grade diamond films that are compatible with standard semiconductor manufacturing techniques.

The innovation is crucial because synthetic diamonds are essential for building quantum memory systems and the photonic interconnects that link individual quantum computers, both of which are key to building scalable quantum networks and clustered compute. The advancement overcomes a major barrier in the production of quantum hardware.

Previously, creating micro- and nano-structured devices from diamonds required bespoke, R&D-scale techniques that were not suitable for reliable, at-scale production. IonQ’s new method allows for the bonding of quantum-grade diamond films onto common substrates like silicon and silicon nitride. This provides two major benefits: foundry compatibility for the mass production of diamond-based quantum devices using the same tools as the $1 trillion semiconductor industry, and heterogeneous integration for the creation of hybrid on-chip systems that combine quantum materials with classical ones.

IonQ Inc. (NYSE:IONQ) develops quantum computers and networks in the US. It sells access to quantum computers of various qubit capacities.
