PRESS RELEASE
Dynex Unveils Zeus-256: Room-Temperature NV-Diamond Quantum Processor Now Available to Customers
Room temperature quantum computing through Dynex QaaS backed by full register entanglement and 84 bit factorisation benchmarks. Quantum is Here.™
Baar, Switzerland - October 2026 Dynex Quantum Technologies AG (www.dynex.co), an award-winning global technology leader headquartered in Switzerland developing quantum and quantum-driven technologies, today announced that Zeus-256, its 256-qubit room-temperature nitrogen-vacancy (NV) diamond quantum processing unit (QPU), is now commercially available to customers through Dynex's cloud-based, qubit-agnostic platform architecture, marking a significant milestone in scientific quantum discovery. Available to read at http://arxiv.org/abs/2610.18245.
The commercial availability of Zeus-256 further strengthens Dynex's first-mover advantage in delivering quantum-driven solutions at industrial scale. Dynex has taken a seat at the forefront of quantum technological innovation and contributes to the acceleration toward mainstream adoption.
Enterprise and research customers can access the processor using the Dynex SDK and OpenQASM, bringing the Company's proprietary gate-based quantum hardware into their computing workflows.[1] Integrated into Dynex's cloud-based, qubit-agnostic platform architecture alongside its Apollo neuromorphic hardware and emulation capabilities, Zeus-256 enables organisations to develop and execute quantum circuits, evaluate quantum workloads and integrate complementary advanced computing technologies into their existing workflows.
Daniela Herrmann, Founder and CEO of Dynex, said:
"Through Dynex Quantum-as-a-Service (QaaS) technologies, our ambition is to bridge the gap between scientific breakthroughs and real-world commercial applications. The Zeus-256 benchmark results strengthen the technological foundation supporting that vision."
A programmable quantum processor for customer workloads
Zeus-256 provides 256 simultaneously active processor-level logical qubits in a 16 x 16 array, without time multiplexing or sequential qubit reuse. Its proprietary, optically programmable biomolecular quantum bus supports interactions between spatially separated fields. The architecture combines NV electron-spin computation with nuclear-spin memory and ancillary resources, and operates at room temperature without dilution refrigeration.[2]
The processor has been exercised across full-register entanglement and quantum Fourier transform circuits, Shor-family factorisation, quantum search, arithmetic, variational algorithms and application-oriented circuits. For customers, this provides a documented technical foundation for evaluating the QPU across different circuit structures and developing workloads suited to the architecture.
Customer availability today
Zeus-256 is available now through Dynex's platform and solution services. Organisations interested in access and application development can contact Dynex at info@dynex.ch or visit www.dynex.co.
The launch comes as commercial room-temperature diamond quantum computing is expanding. SAXON Q's SXQ128 is currently orderable with delivery within three months, while deliveries of its announced SXQ512 are scheduled to begin in Q2 2027.[3] SAXON Q specifies eight entangled qubits per SXQ128 core and 16 per SXQ512 core. Zeus-256 combines current customer availability with reported entanglement across its full 256-qubit register. These different register architectures are material when comparing headline system qubit counts.
Zeus-256 Performance Benchmarks
An academic paper by researchers affiliated with Dynex and the University of Surrey supports customer evaluation of QPU quality through state measurements and algorithm execution.[2] The supporting GHZ measurements, Shor circuits and execution logs-including recovered factors-are published on GitHub for customers and researchers to examine.[4]
Algorithm execution extending beyond fidelity measurements
The Shor-family programme reports factor recovery for all 11 tested integers from 8 to 84 bits. Its largest instance uses the full 256-qubit register and a circuit with 40,250,342 reported gates. The published execution log records the recovered factors 3,798,662,280,499 and 4,344,636,583,747, for the 84-bit target 16,503,807,113,155,763,618,449,753.[2,4]
The arithmetic workloads exercise the integrated compilation, control and readout stack, giving customers evidence of algorithm-level capability beyond state-fidelity measurements.
For perspective, a December 2025 hardware study by researchers at armasuisse, ETH Zurich and the Paul Scherrer Institute tested Shor order-finding circuits for N = 15, 21 and 35, with weaker, base-dependent evidence at N = 35.[5] A June 2026 hardware study of Shor's and Regev's algorithms focused on N = 15.[6] The Zeus-256 target is approximately 4.72 × 10²³ times the numerical value of 35-about 23.7 orders of magnitude larger-and has 14 times its bit length. This comparison describes integer size; computational difficulty also depends on the algorithm and circuit construction, and no corresponding speedup is inferred.
High fidelity across all 256 qubits
The full-register Greenberger-Horne-Zeilinger (GHZ) experiment yielded a state-fidelity point estimate of 99.8960% from 30,000 measurement shots, with a conservative 95% statistical confidence interval of 98.2342% to 100%.[2,4] This provides a measure of the processor's ability to prepare a coordinated entangled state across the complete register.
IBM Quantum's published 120-qubit GHZ experiment reported fidelity of 56% ± 3 percentage points.[7] Zeus-256's reported point estimate is approximately 43.9 percentage points higher, across 2.13 times as many qubits. This comparison illustrates the reported scale and state quality; the experiments use different qubit implementations and measurement procedures, including IBM's error detection, post-selection and readout-error mitigation, and are not a controlled head-to-head test.
Additional measurements include Bell-CHSH correlations of S = 2.8008 ± 0.0446, above the local-classical bound of 2; a three-qubit Grover search success rate of 93.55%, compared with an ideal reference of 94.53%; and execution of a full-register quantum Fourier transform containing 33,024 original OpenQASM gates.[2]
Building on a platform customers can access now
Zeus-256 provides the customer-accessible foundation for Dynex's next engineering target: a 9,984-qubit configuration using the same qubit modality and coupling principle. Scale-up includes control and optical channels, calibration, crosstalk management and manufacturing integration, with validation at increased scale. The processor available today and evaluated in the manuscript is Zeus-256.
Notes to editors
The supporting academic paper is Experimental Benchmarking of a 256-Qubit Room-Temperature NV-Diamond Quantum Processor with an Optically Programmable Biomolecular Quantum Bus, by Adams Ivanov, Daniela Herrmann and Erick Giovani Sperandio Nascimento. Supplementary materials are publicly available at github.com/DynexQuantum/zeus_paper and include 258 GHZ measurement records, analysis code, all 11 Short circuit archives and execution logs recording recovered factors.[2,4]
"Processor-level logical qubit" identifies the addressable electron-nuclear processor-field implementation and does not imply demonstrated fault-tolerant error correction. GHZ fidelity is specific to the measured target state. Its statistical interval assumes trusted local basis rotations and readout, stable preparation and independent trials, and does not include all measurement systematics. Gate counts describe the reported circuits and should be distinguished from compiled native-gate counts.
Comparisons use the named reference experiments and reported central values: 84 versus six input bits; approximately 23.7 orders of magnitude in integer value; 256 versus 120 qubits; and a 43.9-percentage-point GHZ fidelity difference. They do not constitute an exhaustive industry ranking. The 9,984-qubit configuration is a development target.
