Oct 12 (Reuters) – Quantum computing company IonQ said on Monday it would buy cybersecurity firm Elisity in an all-stock deal ​valued at up to $1.3 billion, as ‌it looks to expand its quantum security business.

IonQ said the acquisition would provide it with expanded channels to bring its quantum offerings to both enterprise and ‌government ​customers, helping them deal with ⁠current threats and prepare ⁠for attacks from future quantum computers.

• Elisity, founded in 2019, has more than 100 customer deployments worldwide and has doubled ​its revenue and customer base year-over-year, IonQ said

• The deal value includes up to $150 ⁠million in earn-outs tied to ⁠Elisity’s performance, it added

• The ​number of IonQ shares to be issued will ​be calculated at a price between $33.07 and $49.61 ‌per share

• “Q-Day is coming much faster than predicted,” IonQ CEO Niccolo de Masi said, referring to the point when quantum computers ⁠could break widely used encryption

• Elisity CEO James Winebrenner will continue to lead the acquired business ⁠after the ‌deal closes

• The transaction is expected ⁠to close in the fourth ​quarter ‌of 2026, subject to regulatory approval

• ​IonQ ⁠completed its acquisition of chipmaker SkyWater Technology earlier this year to bring semiconductor manufacturing in-house and boost the development of its next-generation quantum processors
