Challenges and Barriers: Technical, Regulatory, and Supply Chain

Quantum photonic upconversion devices, which convert low-energy photons into higher-energy photons, are emerging as critical components in quantum communication, sensing, and imaging. However, as the field moves into 2025, several challenges and barriers—technical, regulatory, and supply chain—continue to shape the pace and direction of commercialization and deployment.

Technical Challenges remain significant. Achieving high upconversion efficiency at the single-photon level, which is essential for quantum applications, is still a major hurdle. Many devices rely on nonlinear crystals or rare-earth-doped materials, which often require cryogenic cooling or precise phase-matching conditions. Companies such as Hamamatsu Photonics and Thorlabs are actively developing upconversion modules, but scaling these devices for robust, room-temperature operation with low noise and high fidelity is an ongoing research focus. Integration with silicon photonics platforms is another technical barrier, as material incompatibilities and fabrication complexities can limit device performance and scalability.

Regulatory Barriers are beginning to emerge as quantum photonic technologies approach real-world deployment. Quantum communication systems, for example, may be subject to export controls and cryptographic regulations, especially in regions with heightened concerns over data security. International standards for quantum photonic devices are still in development, with organizations such as the International Electrotechnical Commission (IEC) and International Telecommunication Union (ITU) working to establish interoperability and safety guidelines. The lack of harmonized standards can slow cross-border collaboration and market entry.

Supply Chain Constraints are also a pressing concern. The production of high-purity nonlinear crystals, rare-earth elements, and advanced photonic chips is concentrated among a small number of specialized suppliers. For instance, Crylink and CAST Photonics are among the few companies capable of producing custom nonlinear optical materials at scale. Disruptions in the supply of rare-earth elements—often sourced from geopolitically sensitive regions—can impact device availability and cost. Furthermore, the fabrication of integrated photonic circuits for upconversion devices depends on advanced foundries, such as those operated by LioniX International, which face their own capacity and technology transfer challenges.

Looking ahead, addressing these challenges will require coordinated efforts across industry, academia, and regulatory bodies. Advances in material science, standardization, and supply chain diversification are expected to gradually lower barriers, but the timeline for widespread adoption of quantum photonic upconversion devices will likely extend into the latter half of the decade.
