Amazon and Harvard University have created a “quantum network” that transmitted an entangled photon from one quantum computer to another over 35 kilometers of fiber-optic cable. Researchers from Harvard and Amazon’s AWS Center for Quantum Networking put a set of nodes around the Boston area to build a network capable of “efficiently catching, storing, and transferring information initially stored in light.
The photon then makes a round trip through an underground fiber network before returning to Harvard, where it is converted back to visible frequency. > This journey accomplished, the photon is bounced off a different quantum memory in a different lab, thus transferring the entanglement from the photon onto this second memory.
