Quantum Brilliance Quoll at ORNL
Quantum Brilliance Quoll at ORNL is a other quantum computer operated by Oak Ridge National Laboratory in USA. It has 6 physical qubits. It ranks 2 of 4 other machines in this table by physical qubit count. 4 sourced specs are in the spec sheet. No benchmark figures are recorded for it yet.
Also known as Quoll, ORNL Quantum Brilliance QDK cluster
Quantum Computing Report (2 September 2025) calls Quoll ORNL's first on-site commercial quantum computer cluster: three parallelized QPUs giving six qubits in total, run by the Oak Ridge Leadership Computing Facility to study co-scheduling, performance tuning and workflow orchestration with classical HPC. The OLCF write-up says each QDK has a two-qubit QPU, that the team reassembled and calibrated the kit in an ORNL laser lab, and that it sits in the Advanced Computing Ecosystem testbed for OLCF staff; no T2, fidelity or power figures are given. Fraunhofer IAF's release names ORNL as the first buyer of the second-generation QB-QDK2.0 (see quantum-brilliance-fraunhofer-iaf). Not to be confused with the Pawsey Quantum Brilliance accelerator, quantum-brilliance-pawsey, which is a separate site.
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 | Three Quantum Brilliance QDKs, each with a two-qubit diamond QPU | Vendor reported | Total of six qubits across three parallelized QPUs. | quantumcomputingreport.comolcf.ornl.gov |
| Qubit type | nitrogen-vacancy centres in synthetic diamond | Vendor reported | quantumcomputingreport.comolcf.ornl.gov | |
| Cooling and environment | Room temperature, no cryogenics | Vendor reported | olcf.ornl.gov | |
| Access and pricing | On-site cluster for OLCF staff exploring quantum-HPC integration | Vendor reported | olcf.ornl.govquantumcomputingreport.com |
