QuEra Testbed at NQCC
QuEra Testbed at NQCC is a neutral atoms quantum computer operated by National Quantum Computing Centre in United Kingdom. Its physical qubit count has not been published. 4 sourced specs are in the spec sheet. No benchmark figures are recorded for it yet.
Also known as QuEra error-corrected neutral-atom testbed
QuEra said in February 2024 it expected the NQCC testbed to be operational in early 2025. NQCC still describes it as a project to develop an error-corrected testbed, with no delivery date. The pages do not name a Gemini machine or give a qubit count.
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 | QuEra zoned neutral-atom testbed with atom shuttling and error correction | Vendor reported | No qubit count or machine name is stated; NQCC describes a project to develop an error-corrected neutral-atom testbed. | quera.comnqcc.ac.uk |
| Topology | All-to-all gate connectivity through movable optical tweezers in a zoned architecture | Vendor reported | QuEra release of 2024-02-05 describing planned capabilities, not a measured result. | quera.com |
| Access and pricing | On-premises testbed at NQCC Harwell for UK researchers and software developers; no access terms published | Vendor reported | Funded through the NQCC testbed programme under the SBRI framework. | quera.comnqcc.ac.uk |
| Roadmap | Zoned architecture with mid-circuit measurement, aiming at error-corrected operation and logical-qubit experiments | Vendor reported | QuEra said on 2024-02-05 it expected operation in early 2025; NQCC still shows no delivery date. | quera.com |
