Fault-tolerant modular quantum computing with surface codes using single-shot emission-based hardware
An arXiv preprint published on 2026-08-12 proposes a modular fault-tolerant quantum computing architecture combining surface-code error correction with hardware capable of single-shot photon emission. The scheme targets quantum computing using emitted photons for stabilizer measurements and module interconnects.

If single-shot emitters such as quantum dots or color centers can be operated with high efficiency and indistinguishability, this scheme could let early photonic modules perform surface-code stabilizer measurements without probabilistic Bell-pair generation, reducing qubit overhead and enabling small error-corrected demonstration systems within two years.
Single-shot emission removes a major bottleneck in photonic quantum computing, but the architecture still depends on demonstrated emitter performance and low-loss routing. Current photonic platforms have not yet met all threshold requirements, so this is credible but gated on hardware progress.
