Wheel Traps. A Scalable Solution for Quantum Ion Control 

Wheel traps are advanced 3D ion confinement systems used in cutting-edge quantum technologies (QT). Their radial architecture, where electrodes are arranged in a wheel-like pattern, allows precise trapping of ions in vacuum environments. This makes them ideal for applications in quantum computingquantum sensing, and quantum metrology.

Why Wheel Traps Matter

Unlike linear or surface traps, wheel traps offer:

  • Compact 3D geometry for high-density integration
  • Symmetric RF fields (10–100 MHz) for stable ion confinement
  • Multi-zone operation, enabling parallel qubit manipulation

These features support the scalability and precision needed in quantum information processing (QIP).

Microfabrication with Ultrafast Laser Structuring

At FEMTOPRINT, wheel traps are manufactured via ultrafast laser micromachining (ULM) in fused silica (SiO₂). This monolithic fabrication ensures:

  • Resolution: ~1 µm; XY/Z tolerances: ±1–2 µm
  • Aspect ratio: ≥1:500 with ≤0.1° sidewall deviation
  • Surface roughness: Sa ≤ 10 nm (post-treatment)
  • Wafer-scale integration: Up to Ø 300 mm

Glass Advantage for Quantum Platforms

Using optical-grade glass like fused silica ensures:

  • High optical transparency for laser-ion interaction
  • Thermal stability for low-drift performance
  • Vacuum compatibility

Future Integration and Photonic Hybridization

Next-gen quantum systems will require modular ion trap arrays, interconnected by:

  • On-chip integrated optics 
  • Waveguide-coupled ion readout
  • Hybrid platforms combining photonics

Wheel traps are a key enabler of scalable and reliable quantum hardware

Thanks to high-precision glass microfabrication, platforms like those from FEMTOPRINT are setting new standards for the future of quantum-enabled devices (QED).

Optimized for advanced optical atomic clocks, quantum sensors, and quantum cryptography, wheel traps require extreme manufacturing precision. FEMTOPRINT’s capabilities ensure accurate geometries, optical pathways to reduce uncertainties in experimental setups.
