Quantinuum Apollo
Quantinuum Apollo is a trapped ions quantum computer operated by Quantinuum in USA. Its physical qubit count has not been published. 6 sourced specs are in the spec sheet. No benchmark figures are recorded for it yet.
Also known as Apollo
Fault-tolerant machine targeted by the end of the decade with logical error rates below 1e-6. Quantinuum says its Helix architecture, shown on Helios in September 2026, is the path to Apollo. Nothing has been built and no qubit count is fixed.
Spec sheet
Technical details as the builder or a paper states them, each with its own source. A blank is a fact we could not source, not a zero. Fidelity and coherence figures are in the benchmark table below.
| Spec | Value | Basis | Note | Source |
|---|---|---|---|---|
| Processor | Apollo fifth-generation QCCD trapped-ion processor (planned, not built) | Vendor reported | Announced 2024-09-17 as a fifth-generation system with thousands of physical qubits and physical error rate target of 1e-4. | quantinuum.com |
| Topology | 2D array of trapping locations (2D grid), all-to-all connectivity target | Vendor reported | Design statement from the 2024 roadmap post; nothing has been built. | quantinuum.com |
| Native gates | Physical variable-angle one-qubit and two-qubit gates (planned) | Vendor reported | Planned feature list from the 2024 roadmap post. | quantinuum.com |
| Fabrication | Ion trap chip fabricated with standard CMOS processing technology (planned) | Vendor reported | Chip is stated as CMOS-fabricated; separate 2026-09-08 release names GlobalFoundries (300mm wafers) as one foundry for next-generation traps, not specific to Apollo. | quantinuum.comquantinuum.com |
| Predecessor | Quantinuum Sol | Vendor reported | Roadmap runs Helios, then Sol, then Apollo. | quantinuum.com |
| Roadmap | Universal fully fault-tolerant system with hundreds of logical qubits by the end of the decade | Vendor reported | Stated 2024-09-17 with logical error rates better than 1e-6; Quantinuum repeated on 2026-09-08 that Helix on Helios is its path to Apollo. | quantinuum.comquantinuum.com |
