Quantum Startups: Funding & Deals

IonQ announced an all-stock acquisition of Zero Trust security company Elisity valued at up to $1.3 billion, combining IonQ's post-quantum cryptography and quantum key distribution capabilities with Elisity's enterprise platform serving over 100 customers. The deal positions IonQ to address both current LLM threats and emerging quantum threats across the $10 billion microsegmentation market.

The U.S. Department of Energy announced the Quantum Genesis Q Competition with up to $215M in funding to develop quantum computers with at least 100 logical qubits capable of performing hundreds of millions of fault-tolerant operations. Phase II offers $100M split among awardees demonstrating 100 logical qubits, plus $50M bonus pools each for 150 and 200 logical qubits.

Korea Quantum Computing Co., Ltd. announced a definitive business combination agreement with Charlton Aria Acquisition Corporation to list on Nasdaq under the name KQC Quantum, Inc., with proceeds funding commercialization of its Qubiteer AI-driven hybrid quantum platform and quantum-safe security products. KQC has completed quantum computing projects with POSCO Holdings and Busan Transportation Corporation, and post-quantum security proofs of concept with Industrial Bank of Korea and LS ITC.

Shanghai-based Taiyi Quantum closed a new early-stage VC round bringing total funding to over $137.5 million in just eight months since founding, with investors including Jinqiu Fund, Yunbai Capital, and Hongruida Investment. The company has built a prototype ytterbium-atom quantum computing platform with 10-microsecond control latency, open-sourced its LUOSHU quantum compiler, and employs nearly 100 researchers and engineers.

Quantisimo Corp., formed by merging WISeQey and SEALSQ, signed a definitive business combination agreement with GigCapital8 Corp. to list on Nasdaq with a pro forma equity value of approximately $666.1 million at $10 per share. The combined entity will integrate quantum cybersecurity, secure semiconductors, post-quantum security products, and space infrastructure through contributions of Miraex SA, SEALCOIN AG, WeCan Group SA, and WISeSat.Space Holdings Corp.

IonQ demonstrated entanglement rates exceeding 1,000 events per second between a trapped-ion qubit and silicon-vacancy solid-state quantum memory using a photonic interconnect, more than four times faster than the previous trapped-ion record. The breakthrough supports IonQ's participation in DARPA's HARQ program and builds on commercial quantum networking system sales to the University of Maryland and South Korea's SDT.

izmo Microsystems and IIT Madras entered Phase II of the Centre for Programmable Photonic Integrated Circuits and Systems (CPPICS), a five-year silicon photonics program sanctioned by India's Ministry of Electronics and Information Technology with total outlay of ₹99.94 crore. izmo will contribute ₹2.40 crore and develop a 1.6 Tbps silicon photonics transceiver engine for applications including quantum technologies and photonic computing.

Atom Computing, Diraq, IBM, and IonQ advanced to Stage C of DARPA's Quantum Benchmarking Initiative on October 7, joining Microsoft and PsiQuantum to test whether utility-scale quantum systems can be built as designed by 2033. Stage C moves from plans to proof, with DARPA's team directly testing hardware and systems against each company's roadmaps across neutral atom, silicon spin qubit, superconducting, and trapped-ion approaches.

IonQ entered DARPA's Quantum Benchmarking Initiative Stage C under an agreement valued at up to $300 million. This represents a significant government commitment to test IonQ's trapped-ion quantum computing approach against its utility-scale roadmap.

Universal Quantum, a UK-based trapped-ion quantum company, raised over $100 million in Series A funding led by DCVC and Firgun Ventures, the largest Series A for a UK-headquartered quantum firm. The capital will fund development of modular fault-tolerant quantum computing technology and expansion in Singapore, the US, Japan, and Germany.

Oratomic, a neutral-atom quantum company founded in March 2026, announced $775 million in total funding including a Series B led by ARCH Venture Partners, Spark Capital, and Khosla Ventures. The company's founders' research claims that 10,000 reconfigurable atomic qubits could execute Shor's algorithm at cryptographically relevant scales, with 26,000 physical qubits potentially solving discrete logarithms on P-256 in days.
