Abstract
The disclosure includes a multiplexed telecommunication-band quantum network that utilizes atomic arrays in optical cavities. An example quantum networking system includes at least one quantum repeater node. The quantum repeater node includes an array of neutral atoms disposed in an optical cavity and a fiber-optic switch (FOS). The FOS is optically coupled to the optical cavity. The quantum repeater node also includes at least one beamsplitter. The at least one beamsplitter is optically coupled to the FOS.
Claims18
A quantum networking system comprising:
- at least one quantum repeater node, wherein the quantum repeater node comprises:
- an array of neutral atoms disposed in an optical cavity, wherein the array of neutral atoms is formed by using one or more optical tweezers;
- a fiber-optic switch (FOS), wherein the FOS is optically coupled to the optical cavity;
- and
- at least one beamsplitter, wherein the at least one beamsplitter is optically coupled to the FOS.
A quantum networking method comprising:
- providing a first array of neutral atoms in a first quantum repeater node;
- providing a second array of neutral atoms in a second quantum repeater node, wherein providing the first array of neutral atoms and providing the second array of neutral atoms is performed by way of one or more optical tweezers;
- performing atom-photon entanglement of at least one neutral atom of the first array of neutral atoms via a four-wave mixing process so as to form a plurality of atom-photon Bell pairs;
- distributing entangled Bell pairs between the first quantum repeater node and the second quantum repeater node;
- and
- performing an entanglement purification processes on two or more Bell pairs to produce at least one new Bell pair with higher fidelity.
