Element Six (E6), a world leader in synthetic diamond innovation and part of De Beers Group, celebrates the acquisition of Lightsynq, a US-based start-up focused on quantum interconnect solutions in which synthetic diamonds play a key enabling role, by IonQ, a leader in enterprise-grade quantum computing and networking.
This milestone marks a significant step forward in the strategic roadmap for quantum networking and computing, reinforcing the strategic vision behind Element Six’s early investment in Lightsynq, as announced last year.
Founded by Harvard PhD’s and former research leads at the AWS Center for Quantum Networking (CQN), Lightsynq has pioneered photonic interconnect and quantum memory technologies that are essential to scaling quantum systems. Since its initial investment, E6 has proudly supported Lightsynq’s mission to unlock the full potential of these novel technologies through its engineered synthetic diamond solutions.
“From the outset, we recognized Lightsynq’s bold vision and technical excellence,” said Siobhán Duffy, CEO of Element Six. “Its acquisition by IonQ is a testament to the strength of Lightsynq’s innovation and the growing importance of diamond photonics and quantum devices for our future. We are thrilled to continue supporting Lightsynq’s journey as its strategic partner, helping shape the future of scalable, fault-tolerant quantum systems.”
Element Six’s advanced synthetic diamond materials have played a critical role in enabling Lightsynq’s photonic platforms, offering unmatched stability and performance for quantum interconnects.
The partnership between Lightsynq and Element Six, as well as Lightsynq’s recent acquisition by IonQ, demonstrate how fundamental science and engineering expertise can converge to accelerate progress in quantum technologies - one of the most transformative sectors of our time.
