Tungsten-183 nuclear-spin qubits aim for longer coherence and scalable integration
Quantum researchers from the University Paris-Saclay, CUHK and collaborators have demonstrated a new type of solid-state quantum processor based on nuclear spins of tungsten-183. The architecture promises robust qubits that can retain quantum information for extended periods, a cornerstone for practical quantum computers.
Unlike noisy intermediate-scale qubits seen today, this platform focuses on material stability and compatibility with superconducting technologies, making industrial scaling more realistic. By leveraging nuclear rather than electronic spins, the design reduces environmental interference — one of the main enemies of quantum coherence.
If successful, the approach could lead to quantum hardware that is both more compact and more resilient, potentially accelerating the transition from laboratory experiments to real-world commercial systems.
Conclusions:
This development reinforces the growing diversity of quantum architectures. Rather than a single “winner”, multiple platforms may coexist — each optimized for specific workloads such as communication, cryptography, or heavy-duty computation.
