IonQ and Elisity have signed a definitive agreement under which the quantum computing company will acquire the California-based zero-trust access vendor. The all-stock transaction carries a value of up to $1.3B, and as much as $150M of that total is earnout money tied to how the business performs. Closing is expected in the fourth quarter of 2026, provided regulators sign off.
Which users, devices, workloads and AI agents may exchange traffic, independent of the network underneath, is the question Elisity’s software policy layer answers. That capability is what IonQ wants sitting alongside its quantum computing business, where a security arm has been taking shape around post-quantum cryptography and quantum key distribution.
Ordinary intrusions moving at machine speed, and encrypted traffic being harvested today for decryption once quantum machines mature, form the two-front problem the two companies use to frame the deal. Niccolo de Masi, IonQ’s chairman and CEO, told investors that Q-Day is arriving sooner than forecast. Government timelines have already shifted: a recent US executive order pushes federal agencies to accelerate their migration to post-quantum encryption from 2035 to 2030.
Setting those target dates is one thing, meeting them is another, warned Elisity CEO James Winebrenner. His prescription avoids a wholesale rip-and-replace. Instead, teams should shift across whatever is ready, verify that it interoperates, and keep access clamped down on the systems that require additional runway. Ranking what to move first would be aided by adding cryptographic inventory and risk data to Elisity’s IdentityGraph product, under a roadmap that already counts AI agents as subjects of access policy.
