Abstract: A quantum network may use long-lived quantum memories with optical interfaces incorporated into a scalable architecture. Color-center quantum emitters in diamond have emerged as a promising quantum-memory modality due to their optical properties and compatibility with scalable integration. Here, we disclose a cryogenically stable and network-compatible quantum-emitter module for use as a quantum memory. This quantum-emitter module includes a diamond microchiplet with quantum emitters in the form of silicon vacancies or other color centers. The diamond microchiplet is integrated with a silicon photonic integrated circuit (PIC), which is secured to a silicon bench with cryo-compatible epoxy. Waveguides in the PIC are butt-coupled to optical fibers in a silicon V-groove array, which is secured to the same silicon bench with more cryo-compatible epoxy.

Abstract: A system and method for providing customized content using emotional preference is disclosed. In one embodiment, the system comprises a web analytics server, at least one website server and at least one user device all communicating through a network. The web analytics server collects a user's emotional preference and monitors a user's activity on a website. In one embodiment, the system further comprises an advertisement server that customizes advertisement using the information provided. In another embodiment, the system further comprises a recommendation engine and a product provider server. The recommendation engine recommends products from the product provider server and provides a link such that the user can purchase the product online.
