IonQ announces intention to acquire Lightsynq to accelerate company's quantum computing and networking roadmaps

"IonQ's vision has always been to scale our quantum networks through quantum repeaters, and scale our quantum compute power through photonic interconnects. Today's announcement of our intention to acquire Lightsynq helps accelerate both roadmaps," said Niccolo de Masi, CEO of IonQ. "We are pleased to welcome Lightsynq founders Dr. Mihir Bhaskar, Dr. Bart Machielese, Dr. David Levonian and the rest of the Lightsynq team to IonQ. Their groundbreaking technology will accelerate IonQ's commercial quantum computer delivery to 10,000s and ultimately millions of qubits."

Lightsynq was founded by former Harvard quantum networking experts and Amazon Web Services (AWS) Center for Quantum Networking leaders, Dr. Mihir Bhaskar (CEO), Dr. Bart Machielse (CTO), and Dr. David Levonian (CPO) with the goal of building the leading photonic interconnect platform to enable high-fidelity, multi-nodal qubit operations. Lightsynq's approach not only supports modular scalability, but also advances fault-tolerance for creating the world's most powerful interconnected quantum systems. Lightsynq's unique architecture provides a powerful platform to support IonQ's quantum computers and advance the company's quantum networking roadmap.

"We're excited to work alongside the world-class quantum computing and networking teams at IonQ. Together we intend to move faster than any other player in the industry to deliver data-center-scale quantum computers that can deliver transformative value to customers," said CEO of Lightsynq, Dr. Mihir Bhaskar. "Our photonic interconnect will integrate with IonQ's quantum processing units (QPUs) to boost connection speeds and ensure long term market-leading scale and power in quantum computing. Our interconnect will also be critical for IonQ to build the quantum internet, enabling entirely new applications for customers in the financial, telecommunications, aerospace, and defense sectors."

IonQ will also acquire ownership of Lightsynq's portfolio of over 20 technology patents and patent applications related to quantum memory, further strengthening IonQ's growing intellectual property position.

The acquisition of Lightsynq follows IonQ's recent quantum computing and networking momentum, including the recently announced joint development of a new quantum computing innovation center with EPB in Chattanooga, TN, housing the first quantum computing and networking hub in the U.S. IonQ has also recently acquired Qubitekk and ID Quantique, two leaders in the quantum networking industry, and signed networking contracts with defense and intelligence organizations like the Applied Research Laboratory for Intelligence and Security (ARLIS) and the U.S. Air Force Research Laboratory (AFRL).
