Fault-Tolerance Validation of Multi-Qubit Gates
Quantum Art announced on June 16, 2026 that simulations of its trapped-ion multi-qubit gate architecture reveal a finite error-correction threshold near 1 % and decreasing logical error rates as system size grows.
Architecture and Noise Modeling
The design employs all-to-all Mølmer-Sørensen entangling operations; a microscopic noise model captures photon-scattering-induced correlated errors and stochastic Pauli errors, showing error propagation stays confined to gate connectivity.
Lead Researchers
Chief Technology Officer Dr. Amit Ben-Kish co-founded Quantum Art; the study was co-authored by O. Grossman, Y. Kadish, S. Gazit, R. Ozeri and Y. Shapira.
Key Metrics
The simulations show a ~1 % physical error threshold for rotated surface codes; logical error rates improve as the number of qubits increases, enabling circuit-depth compression by orders of magnitude and reducing hardware overhead.
Broader Significance
Demonstrating fault-tolerant multi-qubit gates expands design space for large quantum processors, potentially accelerating applications in optimization, simulation, and advanced computing by significantly substantially lowering circuit depth and control complexity.
Company and Media Commentary
Quantum Art’s press release described the work as a bridge between device physics and error-correction performance; Quantum Computing Report highlighted compatibility verification, while CityBuzz noted resolution of a key industry challenge.

Verbatim Quotes
- “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.,” — Dr. Amit Ben-Kish, CTO and co-founder, Quantum Art
- “For years, the quantum computing industry has largely focused on fault-tolerant systems built from vast numbers of sequential one- and two-qubit operations, leaving open questions about whether large multi-qubit gates could support the same path. Our analysis shows that the errors remain local and controlled, and that a practical threshold exists. That puts multi-qubit gates firmly in the fault-tolerant regime and provides a clear path for scaling such architectures.” — Dr. Amit Ben-Kish
- “PRESS RELEASE — Quantum Art, a developer of full-stack, fault tolerant quantum computers based on trapped-ion qubits and a proprietary scale-up architecture, today announced research results verifying that its multi-qubit gate architecture advances scalable fault-tolerant quantum computing, validated through a detailed microscopic noise model and comprehensive fault-tolerance simulations.” — Quantum Art press release
- “Trapped-ion quantum hardware developer Quantum Art has released comprehensive numerical simulations verifying that its proprietary multi-qubit (MQ) gate architecture is fully compatible with large-scale quantum error correction (QEC).” — Quantum Computing Report
Future Roadmap
Quantum Art plans to build the 1,000-qubit Perspective platform targeting 10-100 logical qubits, followed by the higher-density Landscape series aimed at thousands of logical qubits.
