Equal1 Bell-1
Equal1 Bell-1 is a silicon spin quantum computer operated by Equal1 in . It has 6 physical qubits. It ranks 2 of 2 silicon spin machines in this table by physical qubit count. 11 sourced specs are in the spec sheet. No benchmark figures are recorded for it yet.
Also known as Bell-1 server, UnityQ
Launched in March 2025 at about 1,600 W in a standard rack. Equal1 announced the RacQ successor on 14 May 2026. No customer installation or location was confirmed, so country is blank, and Equal1 publishes fidelity figures only at the level of its silicon spin-qubit platform, not for this 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 | UnityQ 6-qubit quantum system-on-chip | Vendor reported | Equal1 lists a UnityQ 6-qubit quantum processing system in a 600 x 1000 x 1600 mm rack of about 200 kg (March 2025). | ucd.iethequantuminsider.com |
| Qubit type | Silicon electron-spin qubit | Vendor reported | Equal1's technology page describes silicon spin qubits using electron spin up/down; the UnityQ line is family-wide, not Bell-1 specific. | equal1.comthequantuminsider.com |
| Single-qubit gate time | 140 ns | Vendor reported | Average single-qubit gate duration on Equal1's technology page for its silicon spin-qubit work, a family-wide figure not tied to a Bell-1 unit. | equal1.com |
| Two-qubit gate time | 200 ns | Vendor reported | Average two-qubit gate duration on Equal1's technology page for its silicon spin-qubit work, a family-wide figure not tied to a Bell-1 unit. | equal1.com |
| Cooling and environment | Self-contained closed-cycle cryocooler, no dilution refrigerator | Vendor reported | Equal1 states Bell-1 needs no external dilution fridge or special cooling plant. | ucd.iethequantuminsider.com |
| Operating temperature | 300 mK | Vendor reported | Equal1 quotes 0.3 K for the silicon processor; an October 2024 article cited 500 mK for earlier UnityQ plans. | ucd.iethequantuminsider.com |
| Power draw | 1.6 kW | Vendor reported | Quoted as 1600 W from a standard power socket, comparable to an enterprise GPU server. | ucd.iethequantuminsider.com |
| Fabrication | Standard CMOS foundry process, GlobalFoundries 22FDX per Equal1 | Vendor reported | The 22FDX node is from Equal1's technology page for UnityQ; Equal1 also works with TNO nanofabrication facilities in the Netherlands. | equal1.comthequantuminsider.com |
| Access and pricing | Rack-mounted server for on-premises data-centre deployment | Vendor reported | Marketed as plug-and-play for HPC sites; no cloud service or price was found. | ucd.iethequantuminsider.com |
| Successor | Equal1 RacQ | Vendor reported | Equal1 announced RacQ on 15 May 2026 as the next-generation evolution of the Bell-1 server, with the same 1600 W and 0.3 K figures. | thequantuminsider.comequal1.com |
| Roadmap | Scale UnityQ QSoC processors from 6 to 1,000 qubits by 2030 | Vendor reported | Target stated in October 2024; Equal1's roadmap page gives phases (NISQ, early fault-tolerant, fault-tolerant) without dates. | thequantuminsider.comequal1.com |
