Quantinuum Helios Singapore
Quantinuum Helios Singapore is a trapped ions quantum computer operated by Quantinuum in Singapore. It has 98 physical qubits. It ranks 4 of 17 trapped ion machines in this table by physical qubit count. 3 sourced specs are in the spec sheet. No benchmark figures are recorded for it yet.
Also known as Helios SG, Quantinuum Singapore Helios
Announced in November 2025 as the first Helios outside the United States, in partnership with Singapore's National Quantum Office and the National Quantum Computing Hub. Quantinuum's Singapore centre opened in March 2026, and Quantum Computing Report on 13 March 2026 said the Helios was scheduled for deployment later in 2026, so no installed unit is confirmed. Singapore researchers have cloud access to Helios meanwhile. The existing quantinuum-helios record covers the cloud unit.
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 | Helios, 98 fully connected trapped-ion qubits | Vendor reported | Trade report on the Singapore announcement; the same Helios generation as the cloud unit, and no installed Singapore unit is confirmed. | postquantum.com |
| Access and pricing | On-premises hardware-as-a-service at a new Singapore R&D centre, with cloud access for Singapore researchers meanwhile | Vendor reported | Both pages say Singapore researchers got cloud access to Helios immediately while on-premises installation was pending. | quantumcomputingreport.comnqo.sg |
| Roadmap | On-premises Helios installation in Singapore scheduled for later in 2026 | Vendor reported | Quantum Computing Report of 13 March 2026 says the system is scheduled for deployment later this year; the November 2025 NQO page said installation was expected in 2026. | quantumcomputingreport.com |
