Fig. 1. Conceptual illustration of the FPRM and its function demonstrations under different operating types. The bias voltages of the PIN diodes embedded into the reconfigurable meta-particle are controlled via FPGA, which can realize synchronous amplitude modulation with almost fixed phase in orthogonal CP channels. First, in both the ON and OFF states of two PIN diodes, arbitrarily polarized incident waves can be completely reflected and absorbed, respectively. In addition, when the PIN diodes are in transition states, the incident polarized waves can be converted to other polarized waves. The built-in zoom-in-view inset illustrates the detailed structure of the reconfigurable meta-particle in the dashed box. The height of the cuboid represents the amplitude of reflection, and the orange cuboids represent the invariant phase of 𝜃 .

Fig. 1. Schematic diagram of quantum link with quantum repeater. (a) Entanglement swapping between two neighboring elementary links. Each elementary link includes two sources of entangled photon pairs (EPPs), two quantum memories (QMs), and the Bell-state measurement (BSM) device composed of a beam splitter (BS) and two single photon detectors (SPDs). At each end of the elementary link, one member of EPPs is transmitted to the middle point of an elementary link to perform BSM through a long fiber. The result of BSM becomes a heralding signal to herald the establishment of entangled quantum memories at the two end points of each elementary link via entanglement swapping. The other member of EPPs is transmitted to the QM for storage and recall until the entanglement is established for the neighboring elementary link. The recalled member is sent to perform BSM, producing another heralding signal to announce the entanglement between the two neighboring elementary links. The achievement of long-distance entanglement relies on a hierarchical entanglement swapping among these adjacent elementary links. (b) Spectrally multiplexed light–matter interface. A spectrally multiplexed source of EPPs is generated with signal photons at 1532 nm and idler photons at 1549 nm. The signal photons are sent to the on-chip spectrally multiplexed quantum memory (on-chip SMQM) for simultaneous storage and recall, which is based on a fiber-pigtailed laser-written Er3+:LiNbO3 (Er3+:LN ) waveguide. The spectrally multiplexed idler photons and recalled signal photons are sent to a BSM for entanglement swapping.
