Quantum Art, a developer of full-stack fault-tolerant quantum computers based on trapped-ion qubits, announced research results verifying that its multi-qubit gate architecture advances scalable fault-tolerant quantum computing. The validation, detailed in a paper titled "Trapped-Ion Multi qubit Gates are Compatible with Scalable Quantum Error Correction," demonstrates that multi-qubit gates can support fault-tolerant operation under realistic noise conditions.
The research, published on June 16, 2026, shows that by constructing a detailed microscopic noise model and performing comprehensive fault-tolerance simulations, Quantum Art's architecture exhibits a finite threshold at the 1% level using surface codes. This threshold is a key benchmark for scalable fault-tolerant quantum computing. Importantly, the results indicate that logical error correction continues to improve as the system scales, affirming the architecture's viability.
Dr. Amit Ben-Kish, CTO and co-founder of Quantum Art, stated: "The most important result is that multi-qubit gates, favorable candidates for large scale quantum computation schemes, are also fully compatible and advantageous for fault tolerant codes." He added that while the industry has focused on systems built from sequential one- and two-qubit operations, the analysis shows that errors from multi-qubit gates remain local and controlled, with a practical threshold existing.
Quantum Art's multi-qubit gate architecture offers significant advantages in computational efficiency, circuit compression, and system scalability. The findings reveal that although all-to-all connected multi-qubit gates enable circuit depth compression and reduced computational overhead by orders of magnitude, error propagation remains small and bound by the gate's connectivity mapping. This provides strong evidence that the architecture can scale while remaining compatible with fault-tolerant quantum computing requirements.
The milestone validates Quantum Art's roadmap toward large-scale fault-tolerant systems, including its planned Perspective platform, a 1,000-qubit multi-core quantum computer designed to support commercially relevant applications with 10s-100 logical qubits, and the next-generation Landscape series supporting 1000s of logical qubits. The full research is available here.
Quantum Art, founded in 2022 and spun out from Prof. Roee Ozeri’s research group at the Weizmann Institute of Science, develops systems and solutions for complex computational problems using a full-stack trapped-ion quantum computing approach.
