Azure Quantum — Quantinuum H2 Standard

Quantinuum H2 (56-qubit trapped-ion, QCCD) · trapped-ion · 56 physical qubits · 12 logical · 99.80% 2Q fidelity

verified primary

Pricing model

$125,000 per month subscription. Includes 10,000 HQCs on H2 hardware + 100,000 eHQCs on emulator. HQC formula = 5 + C(N_1q + 10·N_2q + 5·N_m) / 5000.

1.Representative workload costs

Concrete circuit costs for common workload sizes. Where the pricing model is non-linear (per-program minimums, per-month subscriptions), the table surfaces the floor and break-even points.

Table 1 — Workload cost reference

Workload	Cost (USD)	Note
$125K/mo subscription	$125,000	Floor cost. Not divisible.
10,000 HQCs on H2 hardware	Included	Effective per-HQC: $12.50 — but only useful if your workload structure earns the HQCs back.
100k eHQCs on emulator	Included	Useful for algorithm development before paying H2 HQCs.

2.Structural hardware advantage

56-qubit trapped-ion QCCD (Quantum Charge-Coupled Device) architecture from Quantinuum H2. 99.8% 2Q fidelity is the highest production figure in the cohort. 12 logical qubits demonstrated in 2024 Microsoft + Quantinuum collaboration — the only commercial hardware claiming logical-qubit demonstration at scale.

3.Position in the 2026 stack

Production, premium-tier. Quantinuum H2 is the highest-fidelity production trapped-ion hardware. The QCCD architecture is the technical bet for fault-tolerant quantum computing.

4.Best-fit workloads

Production quantum chemistry workloads (deep circuits)
Algorithm research that benefits from logical-qubit demonstrations
Frontier R&D buyers prioritising fidelity over per-shot cost

5.Pricing trap

Watch for: HQC formula is non-trivial. Run the formula on your representative circuit before subscribing — workloads with high 2-qubit gate counts burn HQCs fast. The 10K hardware HQC allocation feels generous until you compute it against a deep-circuit workload.

Verification note. $125K/mo includes 10k HQCs on H2 + 100k eHQCs on emulator. HQC = 5 + C(N_1q + 10·N_2q + 5·N_m)/5000.
