IonQ to Acquire Geneva-Based ID Quantique, Enters Into Global Quantum Strategic Partnership with SK Telecom

ID Quantique's renowned team, technology, and products to join IonQ portfolio

With addition of nearly 300 quantum networking patents from ID Quantique; issued and pending quantum patents IonQ controls will total more than 900 worldwide

SK Telecom and IonQ enter into Memorandum of Understanding for strategic partnership

Acquisition furthers IonQ's leading position in the global quantum networking market

Today, IonQ (NYSE:IONQ) announced that it has reached a definitive agreement with each of SK Telecom and ID Quantique (IDQ), a global leader in quantum safe networking and sensing headquartered in Geneva, Switzerland with offices in Seoul (South Korea), Vienna (Austria), and Boston (USA), to acquire a controlling stake in IDQ. Alongside the transaction, IonQ expects to enter into a strategic partnership focused on quantum with SK Telecom, the largest wireless telecommunications operator in South Korea.

The transaction consideration will be paid in IonQ common stock.

As part of the transaction, once closed, IonQ will bring IDQ's team, pioneering products, and growing book of quantum networking business into its global quantum ecosystem. In addition, IDQ's patent portfolio of nearly 300 patents and patent applications will bring the total count of granted and pending patents that IonQ owns or controls to nearly 900.

"This strategic transaction and the expertise of ID Quantique furthers IonQ's role as a global leader in next generation secure communications," said Peter Chapman, Executive Chair of IonQ. "And once finalized, we expect that our intended strategic partnership with SK Telecom, one of the most powerful technology companies in Asia, will significantly enhance the distribution of IonQ quantum technology, leading to many commercial and technical opportunities."

SK Telecom has a pioneering history in quantum networking, having deployed the largest quantum network in South Korea.

"Quantum technology is not an option but an essential element for the advancement of AI," said Ryu Young-sang, CEO of SK Telecom, who further explained the reason for the strategic partnership with IonQ by stating, "SKT will continue to make proactive investments and collaborations to become a leading company in the AI field."

With more than 20 years of experience, IDQ offers a broad range of products across quantum networking and quantum-safe communication, including quantum key distribution, quantum random generators and quantum detection systems, key pillars of the quantum industry. IDQ has been deploying quantum-safe networks around the world. Recent examples are the implementation of the Nationwide Quantum Safe Network Plus (NQSN+) in Singapore, the deployment of a 800km-long nationwide network in South Korea as well as key projects as part of Europe's quantum communications infrastructure (EuroQCI). In addition, ID Quantique commercializes high-performance single-photon detectors which are key components to build quantum memories and scalable quantum computers. McKinsey estimates that the quantum networking market will grow to between $10-15 billion by 2035¹ – scaling to become as large if not larger than the quantum computing industry itself.

"ID Quantique is excited to be joining the IonQ portfolio, to continue its journey providing quantum networking technology worldwide," said Grégoire Ribordy, Co-Founder and CEO of IDQ. "IonQ has been a pioneer in the quantum industry, developing powerful computing systems combined with dedication to quantum networking–vital infrastructure underpinning the entire global economy. We have long admired IonQ's work, and know that the combination of IDQ and IonQ will be powerful, accretive, and impactful worldwide."

IonQ and IDQ believe quantum networks will be fundamental infrastructure in the future, with uses in many important sectors, especially defense, finance, and energy. The technology allows many nodes to communicate using entangled qubits, resulting in highly secure communications, precise timing, distributed quantum computing, and quantum sensing.

IonQ has long recognized that quantum networking is a key strategy to scale its quantum computers. IonQ's architecture intends to use photonic interconnects to create a more powerful computing cluster by networking multiple quantum computers together. The years IonQ has spent developing this technology for its distributed computing efforts have allowed it to move quickly in advancing its quantum networking offerings.

IonQ anticipates closing the acquisition in the next nine months, subject to the satisfaction of customary closing conditions.

IonQ's transaction with IDQ directly follows a series of recent announcements from IonQ in the quantum networking space. Last month, IonQ announced the consummation of its acquisition of substantially all of the assets of Qubitekk, Inc., a quantum networking leader in the U.S., bringing Qubitekk's team, customer base, and portfolio of 118 U.S. and international patents in quantum networking to IonQ. IonQ also announced the close of two quantum networking contracts with the United States Air Force Research Lab (AFRL) in 2024, including the largest known 2024 U.S. Quantum Contract Award of $54.5 million to design, develop and deliver quantum networking technology as well as another $21.1 million award that involves the creation of groundbreaking capabilities to establish free-space optical links from ground stations to drones.

IonQ has also demonstrated growing momentum in South Korea. In January 2025, IonQ also announced the signature of a Memorandum of Understanding with the Metropolitan Government of Busan, the second largest city in South Korea known as a key technology and economic hub, to advance quantum technology. Previously, IonQ has announced customer contracts and strategic partnerships with Hyundai Motor Group and Sungkyunkwan University (SKKU), a leading university based in Seoul. The expected strategic partnership with SK Telecom builds on IonQ's history of success in South Korea.
