# Is Open-Source Trapped-Ion Hardware Finally Becoming Manufacturable?

South Korean systems integrator SDT is now the primary hardware manufacturing partner for Open Quantum Design (OQD), the Canadian non-profit that publishes fully open-source trapped-ion quantum computer blueprints. The agreement, announced at Quantum Korea 2026, assigns SDT responsibility for fabricating physical trapped-ion quantum processing units (QPUs) directly from OQD's publicly available schematics — covering ultra-high vacuum (UHV) chambers, microfabricated surface ion-trap electrodes, and free-space laser optics — and for building the control electronics and user-interface software needed to make those systems commercially deployable.

The partnership is a concrete test of whether open-source hardware models can survive contact with real manufacturing constraints. OQD's value proposition is reproducibility: universities, national laboratories, and defense agencies should be able to obtain a complete, documented quantum system without depending on a single proprietary vendor. SDT's role is to close the gap between a published schematic and a functioning QPU that ships to a customer.

Separately, SDT is running its QuREKA Quantum Computing as a Service (QCaaS) platform out of a Quantum-AI Hybrid Data Center in Seoul, integrating [IonQ](https://quantumintel.tech/companies/ionq) trapped-ion systems alongside local superconducting QPUs and classical emulators — including QPerfect's MIMIQ engine — to target South Korea's bio-pharmaceutical sector.

## What OQD Actually Publishes — and What SDT Must Build

OQD's open-source stack is unusually complete for the quantum hardware space. The organization releases public designs for UHV chamber assemblies, surface ion-trap electrode geometries, control electronics schematics, laser optics layouts, and an open software stack with drivers. This is not a software API or an abstraction layer — it is, in principle, a buildable system.

SDT's manufacturing mandate covers the full hardware stack:

- **Precision fabrication** of vacuum ion traps from OQD's electrode designs
- **Free-space optical assembly** for the laser systems that manipulate trapped ions
- **Control electronics** build-out
- **Co-development of user-interface software**, including integration with SDT's QuREKA QCaaS cloud interface

SDT has also joined the preferred-supplier network for LightFlow, a cloud-based design and manufacturing platform for free-space optical systems, giving it a role in producing optical subsystems for OQD deployments beyond the primary manufacturing agreement.

The [coherence time](https://quantumintel.tech/glossary/coherence-time) and [gate fidelity](https://quantumintel.tech/glossary/gate-fidelity) characteristics of the resulting systems are not specified in the announcement — a notable gap. Open-source blueprints are only as good as the manufacturing tolerances applied to them, and surface ion traps are acutely sensitive to electrode fabrication quality, surface contamination, and stray electric fields. Whether SDT can hit the fidelity floors required for scientifically useful operation will determine whether this partnership produces real instruments or demonstration units.

## The QuREKA Platform: A Parallel Commercial Bet

Independently of the OQD agreement, SDT is building commercial quantum-classical compute access through its QuREKA platform. The system, operated from SDT's Seoul data center, integrates CUDA-Q toolchains with three compute modalities: local superconducting QPUs, [IonQ](https://quantumintel.tech/companies/ionq) trapped-ion systems accessed externally, and high-performance classical emulators via QPerfect's MIMIQ engine. The target application domain is bio-pharmaceutical — specifically molecular modeling, protein structure analysis, and drug candidate discovery.

This positions QuREKA as a [hybrid quantum-classical](https://quantumintel.tech/glossary/hybrid-quantum-classical) stack aimed at near-term, domain-specific workloads rather than fault-tolerant computation. The inclusion of QPerfect's MIMIQ emulator is strategically significant: it allows QuREKA to benchmark and develop quantum circuits at scales that current hardware cannot execute, maintaining commercial utility while physical qubit capabilities mature. (BTQ's acquisition of QPerfect for this purpose is covered separately in our prior reporting.)

The bio-pharma focus is commercially sensible. Molecular simulation is one of the few application areas where quantum hardware — even [NISQ](https://quantumintel.tech/glossary/nisq)-era devices — can plausibly offer near-term value, and South Korea's pharmaceutical sector represents a concentrated, well-funded domestic customer base.

## Geographic Ambition: ASEAN and South America

Led by SDT CEO Ji-won Yoon and OQD Co-Founder and CEO Greg Dick, the alliance explicitly targets expansion of OQD's open-source ecosystem across the ASEAN region and South America. This is a meaningful geographic bet. Both regions have growing national quantum programs but limited domestic hardware manufacturing capacity, making them plausible early adopters of a reproducible, open-source system that does not require vendor lock-in to a North American or European supplier.

SDT's position as a South Korean systems integrator gives it supply-chain and regulatory credibility across ASEAN markets that a Canadian non-profit alone would struggle to establish. Whether OQD's open-source model can compete with proprietary offerings from well-capitalized vendors — in regions where procurement decisions often favor established relationships — remains an open question.

## Industry Context: Open Hardware as Infrastructure

OQD's model is structurally different from every major commercial trapped-ion vendor. [IonQ](https://quantumintel.tech/companies/ionq), Quantinuum, and Alpine Quantum Technologies all maintain proprietary hardware stacks. OQD is betting that the quantum industry needs something analogous to open-source software infrastructure: a shared, auditable hardware foundation that lowers entry barriers for research institutions and national programs that cannot or will not pay commercial system prices.

The SDT partnership is the most concrete step OQD has taken toward making that model manufacturable at scale. The critical validation — systems delivered, characterized, and performing at specified fidelity — is still ahead.

## Frequently Asked Questions

**What is Open Quantum Design (OQD)?**
OQD is a Canadian non-profit that develops and publicly releases complete, open-source blueprints for trapped-ion quantum computers, including hardware schematics for vacuum systems, ion-trap electrodes, laser optics, control electronics, and software stacks.

**What will SDT actually manufacture for OQD?**
SDT will fabricate physical trapped-ion QPU hardware modules — including UHV chambers, microfabricated surface ion-trap electrodes, and free-space laser optical assemblies — build control electronics, and co-develop user-interface software based on OQD's open-source designs.

**What is the QuREKA platform?**
QuREKA is SDT's Quantum Computing as a Service (QCaaS) platform, operated from a Quantum-AI Hybrid Data Center in Seoul. It integrates CUDA-Q toolchains with IonQ trapped-ion systems, local superconducting QPUs, and QPerfect's MIMIQ classical emulator, targeting bio-pharmaceutical research workloads.

**How does this compare to commercial trapped-ion vendors like IonQ or Quantinuum?**
Those vendors maintain proprietary, closed hardware stacks. OQD's model publishes complete schematics so that universities, research labs, and government agencies can procure or build systems without single-vendor dependency. Whether open-source manufacturing can match proprietary fidelity benchmarks is unproven.

**Which regions does the SDT-OQD partnership target?**
The alliance explicitly targets ASEAN (Southeast Asia) and South America as primary expansion markets, in addition to SDT's existing South Korean base.
