Quantinuum

What Quantinuum does

Quantinuum is a full-stack quantum computing company formed in November 2021 from the merger of Honeywell Quantum Solutions and Cambridge Quantum Computing, headquartered in Broomfield, Colorado, with engineering operations in Cambridge, UK. The company builds and operates trapped-ion quantum computers based on its proprietary Quantum Charge-Coupled Device (QCCD) architecture, with a current flagship system Helios offering 98 physical qubits, 48 logical qubits, all-to-all connectivity, and a 99.921% average two-qubit gate fidelity independently validated by Sandia National Laboratories and published in Nature. The product portfolio spans three generations of hardware (H1 linear, H2 racetrack, Helios), the Nexus cloud platform for unified access, and a vertically integrated software stack including the TKET compiler, InQuanto computational chemistry suite, Quantum Origin quantum random number generator, Guppy programming language, and lambeq for quantum natural language processing.

Quantinuum generates revenue through four primary streams: Hardware-as-a-Service for on-premise deployment of quantum systems (notably used by research institution Riken, which accounts for over half of 2024 revenue), cloud-based Quantum-as-a-Service access via the Nexus platform, software and developer tool licensing, and enterprise consulting for algorithm co-development with named clients including BMW Group, JPMorganChase, bp, SoftBank, Synopsys, and Amgen. Distribution combines direct enterprise field sales with channel partnerships through IBM's quantum network, HPE Cray supercomputing integration, AWS Braket, and Microsoft. FY2025 revenue was $30.9 million (up 35% from $23 million in FY2024) with FY2025 bookings of $79.3 million against a net loss of $192.6 million and approximately $263 million in free cash flow burn.

The company completed its IPO on Nasdaq under ticker QNT on June 4, 2026, raising $1.68 billion at a $15.6 billion valuation in the largest pure-play quantum computing IPO on record, with Honeywell retaining approximately 49.1% voting control. The capital base supports a hardware roadmap targeting Sol and Apollo systems planned for 2029 with hundreds of logical qubits, alongside $100 million in US Department of Commerce preliminary funding under the CHIPS quantum initiative. Quantinuum competes in the early-stage fault-tolerant quantum computing market alongside IonQ, Rigetti, IBM, and Google, with differentiators centered on trapped-ion fidelity, all-to-all connectivity, and full-stack software integration validated by peer-reviewed publications and strategic partnerships with Microsoft, Sandia, and major enterprise end-users.
