QuiX Quantum said its newly installed Feed-Forward Control Unit closes a deterministic 150-nanosecond loop from single-photon detection to settled on-chip output, enabling real-time adaptive operations in its photonic quantum stack.
The module targets measurement-based photonic computing, where later circuit routing must change instantly based on intermediate photon detections traveling at light speed through optical paths.
Dual FPGA processors, a custom analog front end, and a 32-input, 32-output routing matrix translate detector signals into immediate phase changes before a target photon moves about 30 meters through telecom fiber.
The installation completes a control layer in QuiX Quantum's full-stack platform, replacing static calibration of Mach-Zehnder interferometers with programmable optical routing.
QuiX says that hardware-level feedback is meant to support larger-scale universal photonic operations and tighter links between quantum systems, HPC infrastructure, and AI networks.
