Fig. 1: Illustration of proposed TFLN-enabled quantum node.

Light from a laser is fiber-coupled to TFLN PIC and then passes through a laser control unit (LCU) that consists of an amplitude modulator (AM) followed by a phase modulator (PM). The LCU provides amplitude and frequency control of the input CW laser, needed to address a quantum memory module (Q-Mem). We emphasize that while the Q-Mem is shown on chip for illustrative purposes, it can be effectively linked to the main control PIC via optical fiber and low-loss couplers demonstrated in this work. Another PM enables frequency control of single photons entangled with the Q-Mem. Finally, a switch network is used to multiplex the various memories together. Photons passed through the switch are routed to either on-chip single photon detectors (SNSPDs) or to a low-loss output fiber coupler to route photons to the off-chip fiber network.
