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 supports scalable fault-tolerant quantum computing. The findings, published in a paper titled 'Trapped-Ion Multi qubit Gates are Compatible with Scalable Quantum Error Correction,' demonstrate a practical fault-tolerance threshold at the 1% level using surface codes, validating a scalable path toward logical qubits.
The research constructed a detailed microscopic noise model for multi-qubit gates and analyzed the performance of such models in scalable error correction codes. The results showed that dominant noise sources can be described as effective single- and two-qubit error channels, aligned with the gate's multi-qubit connectivity mapping, while unwanted long-range error propagation remains significantly weaker. This finite-threshold behavior provides an important bridge between device-level physics and quantum error-correction performance.
Dr. Amit Ben-Kish, CTO and co-founder of Quantum Art, emphasized the significance: '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. 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.'
Quantum Art's multi-qubit gate architecture offers significant advantages in computational efficiency, circuit compression, system scalability, and overall hardware footprint. The findings show that all-to-all connected multi-qubit gates enable circuit depth compression and reduced computational overhead by orders of magnitude, while error propagation remains small, controlled, and bound by the gate's connectivity mapping. This provides strong evidence that Quantum Art's 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 quantum applications with 10s-100 logical qubits, as well as the next-generation Landscape series supporting 1000s logical qubits. The research results are detailed in the paper authored by O. Grossman, Y. Kadish, S. Gazit, A. Ben-Kish, R. Ozeri, and Y. Shapira, available here.
