Quantum Art, a developer of full-stack, fault-tolerant quantum computers based on trapped-ion qubits, announced on June 16, 2026, that its multi-qubit gate architecture supports scalable fault-tolerant quantum computing. The findings, validated through detailed microscopic noise modeling and fault-tolerance simulations, demonstrate a practical threshold for error correction, a crucial step toward building large-scale quantum systems.
The company's research shows that multi-qubit gates, which offer computational efficiency and reduced overhead, exhibit controlled error propagation. The simulations revealed finite-threshold behavior at the 1% level using surface codes, indicating that logical error correction improves as the system scales. This validates that multi-qubit gates are not only efficient but also compatible with fault-tolerant codes, addressing long-standing questions in the field.
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 emphasized that errors remain local and controlled, providing a clear path for scaling such architectures.
The research, detailed in the paper 'Trapped-Ion Multi qubit Gates are Compatible with Scalable Quantum Error Correction' by O. Grossman, Y. Kadish, S. Gazit, A. Ben-Kish, R. Ozeri, and Y. Shapira, is available on the company's website. The milestone supports Quantum Art's roadmap toward its Perspective platform, a 1,000-qubit multi-core quantum computer, and the next-generation Landscape series with thousands of logical qubits.
Quantum Art, founded in 2022 and spun out from Prof. Roee Ozeri’s research group at the Weizmann Institute of Science, focuses on trapped-ion quantum computing for optimization, simulation, and advanced computing applications. The company's architecture combines scalable hardware with software for real-world problems.
