- All-stock deal includes up to $150 million in performance earnouts
- Elisity brings more than 100 global customer deployments
- Deal to close in the fourth quarter, pending regulatory approval
IonQ has agreed to acquire zero trust security company Elisity in an all-stock transaction valued at up to $1.3 billion, adding network access controls to a quantum security portfolio the company has been assembling through acquisitions throughout the year.
The College Park, Maryland, company said Monday the deal includes up to $150 million in earnouts tied to Elisity’s performance and is expected to close in the fourth quarter pending regulatory approval.
Elisity will continue operating under CEO James Winebrenner after closing.

Quantum threats and cryptographic migration are reshaping federal security planning. The Potomac Officers Club will host the 2027 Defense R&D Summit on Feb. 4 in Virginia, where Department of War and national security technology officials will discuss quantum computing, trusted AI and battlefield information dominance.

What Does Elisity Offer?
Founded in 2019 and based in California, Elisity offers a software policy layer that governs which users, devices, workloads and artificial intelligence agents can communicate across a network, then enforces those limits without depending on the underlying network technology. Its IdentityGraph product pulls identity, asset and risk data from native and partner sources to set least-privilege rules, which teams can simulate before switching on.
The company reported more than 100 global deployments and said revenue and customer counts have doubled year over year with no churn among deployed customers. IonQ put the microsegmentation market Elisity competes in at more than $10 billion.
IonQ has built a security arm around post-quantum cryptography and quantum key distribution, and said it has deployed quantum-safe national communications networks in Switzerland, Poland, Romania and Slovakia. According to the company, Elisity’s customer base and relationships with chief information security officers give IonQ additional channels into enterprise and government networks.
What Is Driving the IonQ-Elisity Deal?
The deal’s timing tracks a federal deadline. Executive Order 14412, signed in June, directs agencies to move high-value assets and high-impact systems to post-quantum cryptography for key establishment by the end of 2030 and for digital signatures by the end of 2031, excluding national security systems. The order also requires the Federal Acquisition Regulatory Council to propose a rule requiring covered contractors to meet National Institute of Standards and Technology-approved Federal Information Processing Standards that incorporate post-quantum algorithms by the end of 2030. CyberScoop reported that the order advanced the federal migration target from 2035.
Meeting those dates will take sequencing. Winebrenner told CyberScoop that enterprises first have to identify what needs protecting, then map the identities, communications and cryptographic dependencies supporting it, migrating what they can while tightly controlling access around systems that need more time. Under a shared road map, IonQ will provide IdentityGraph with cryptographic inventory and risk information, which could help customers decide which systems to upgrade first.
IonQ’s government footprint is widening on other fronts. The company signed memorandums of understanding in the second quarter with Anduril Industries, covering quantum technologies for defense and national security and joint proposals for government bids, and with Sandia National Laboratories on quantum co-design.
How Does the Deal Fit IonQ’s Acquisition Run?
The Elisity transaction marks the latest in a series of strategic acquisitions for IonQ this year. In January, the company completed its purchase of Skyloom Global, adding free-space optical communications and photonic systems engineering to advance its quantum networking road map. IonQ followed with a $1.8 billion deal for SkyWater Technology, a U.S.-based semiconductor foundry that now operates as a subsidiary under CEO Thomas Sonderman, who reports to IonQ Chairman and CEO Niccolo de Masi. In September, IonQ acquired Nexus Photonics to drive integrated photonics and hardware miniaturization.
IonQ reported second quarter revenue of $80.1 million, up 287 percent year over year.
