Scalable Photonic Platform for Real-Time Quantum Reservoir Computing

Quantum Reservoir Computing (QRC) exploits the information processing capabilities of quantum systems to solve non-trivial temporal tasks, improving over their classical counterparts. Recent progress has shown potential QRC exploiting enlarged Hilbert space, but real-time and achievement a advantage with efficient use resources are prominent challenges towards viable experimental realizations. In this work, we propose photonic platform suitable for based on physical ensemble reservoirs in form identical optical pulses recirculating through closed loop. While ideal operation achieves maximum capacities, statistical noise is undermine advantage. We strategy overcome limitation sustain performance when size system scaled up. The conceived implementations be current technology.
