Beijing is explicitly treating photonic chips—which use light instead of electrons—as a sanctions-evasion pathway, since current US export controls target silicon-based semiconductors but lack equivalent restrictions on optical computing architectures. Photonic systems face different manufacturing constraints than traditional chips and may be harder to choke off through existing supply-chain leverage, though they're still years from commercial viability at scale. The move suggests China won't wait for semiconductor self-sufficiency through incremental node advances; instead it's hedging by pursuing computing paradigms that weren't contemplated in the original restrictions regime.
