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 findings, validated through a detailed microscopic noise model and comprehensive fault-tolerance simulations, demonstrate that multi-qubit gates can support fault-tolerant operation while maintaining compatibility with quantum error correction codes.
The company's architecture was tested by constructing realistic noise models for multi-qubit gates and analyzing their performance in scalable error correction codes. The results show a finite-threshold behavior at the 1% level using surface codes, a key benchmark for scalable fault-tolerant quantum computing. Importantly, the simulations revealed that logical error correction continues to improve as the system scales, providing a bridge between device-level physics and error-correction performance.
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 the industry has largely focused on systems built from one- and two-qubit operations, leaving questions about whether large multi-qubit gates could support fault tolerance. '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 advantages in computational efficiency, circuit compression, system scalability, and hardware footprint. The findings show that while 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 quantum applications with 10s-100 logical qubits, as well as the next-generation Landscape series supporting 1000s of logical qubits. The results are detailed in the paper 'Trapped-Ion Multi qubit Gates are Compatible with Scalable Quantum Error Correction,' authored by O. Grossman, Y. Kadish, S. Gazit, A. Ben-Kish, R. Ozeri and Y. Shapira, and is available here.
