Quantum repeater for optical network and method

A quantum repeater system including a plurality of nodes, including an end node coupled to a quantum computer device, the system comprising:

• one or more intermediary repeater devices numbered from 1 to N, where N is an integer greater 1;
• each of the repeater devices comprising:
• a first fiber optical cable having a first end region and a second end region, the first end region having a first end, and the second end region having a second end;
• a first fiber Bragg Grating configured on the first end region;
• a second fiber Bragg Grating configured on the second end region;
• a nanofiber region configured from a center portion of the fiber optic cable and coupled between the first end region and the second end region;
• a first taper region configured from a first portion of the nanofiber region within a vicinity of the first fiber Bragg Grating and a second taper region configured from a second portion of the nanofiber region within a vicinity of the second fiber Bragg Grating;
• a cavity formed from the nanofiber and tapered regions between the first fiber Bragg Grating and the second fiber Bragg Gratings;
• a plurality of atoms comprising an alkali metal atom including a cesium and a rubidium, an alkaline-earth metal and an alkaline-earth-like atom including an ytterbium or a strontium and other laser coolable atoms such that a number of the atoms range from one to 100,000 and are evanescently coupled at least the nanofiber region between the first fiber Bragg grating and the second fiber Bragg grating;
• an optical system comprising an imaging system, the optical system comprising an optical tweezer array and an optical addressing tweezer array to trap and manipulate two or more of the plurality of atoms;
• and
• an optical cable coupled between each pair of repeater devices to configure the initial quantum repeater device, the intermediary repeater device, and final quantum repeater device in a serial connection by transmitting one or more photons from the initial quantum repeater device to a neighboring intermediary repeater device to then to the neighboring final quantum repeater device to distribute a quantum entanglement between a pair of adjacent quantum repeaters.
