Building hardware and the Nexus platform
Quantinuum published a roadmap on Nov. 6 for Nexus, the cloud platform where customers write, test and run quantum programs. The plan ties each software release to a hardware generation: Helios today, Sol in 2027 and Apollo, a fault-tolerant machine, in 2029.

Targeting fully accurate, reliable quantum computers by 2029
Quantum computers could help with drug discovery, codebreaking and materials science, but only if they grow from dozens of quantum bits (qubits) to millions. The bottleneck is control: each qubit needs precisely steered light or microwaves, and thousands of cables run into refrigerators colder than deep space. Chipmakers are trying to move that control hardware onto standard production lines, as CU Boulder's December 2025 optical modulator did.

As of September 2026: Operator of the H2 trapped-ion processor used in the experiment
Researchers have shown that exotic quasiparticles called non-Abelian anyons can perform every operation a general-purpose quantum computer needs. Using 54 entangled qubits on Quantinuum's H2 trapped-ion processor, a team from the University of Chicago, Harvard, Stony Brook University, and Quantinuum combined two operations, braiding and fusion, to reach universal computation for the first time in a non-Abelian code.

As of May 2026: Filed confidential IPO registration targeting $20B+ valuation
D-Wave Quantum closed its $550 million acquisition of Quantum Circuits in January 2026, adding Yale's dual-rail qubit technology to its quantum annealing platform. The deal is part of a nine-month consolidation spree: IonQ spent $1.08 billion on Oxford Ionics in June 2025 and announced a $1.8 billion SkyWater Technology acquisition in January 2026.
