Trapped Ions Are Moving into the Fab

TRAPPED IONS · MANUFACTURING

Trapped ions are moving into the fab.

Manufacturing, control and cooling must scale together

01

Control

• Microwave-driven approaches
• Control closer to the qubits

02

Manufacture

• Foundry process compatibility
• Repeatable device fabrication

03

Integrate

• Packaging and interconnects
• Architecture-specific cooling

Watch for: Process repeatability · Packaging yield · System benchmarks

Scaling qubits is not the same as scaling quantum computers. Here's how manufacturing and control shape trapped-ion systems

Lasers → Microwaves

• Universal Quantum and eleQtron control ions with microwaves
• Control moves onto the chip
• A simpler control stack

Lab → Fab

• Universal Quantum's iQPU, with hundreds of ion qubits, is built on a standard 200mm line
• Quantinuum × GlobalFoundries on 300mm
• Quantum starts to follow semiconductor logic: yield and cost per qubit

Cooling needs differ

• Superconducting: cryogenic is a must
• Trapped ions: cooling is an option, for performance

Not solved yet. System-level data will tell. But the quantum race is increasingly a manufacturing race.

As control electronics move closer to the qubits, will cryogenic semiconductors become the cross-platform layer? And where does Taiwan fit?
