    摘要: Described herein are systems and methods for assessing a computing network's physical robustness to node and/or link failure during operation of the computing network. In one or more examples, the systems and methods can incorporate graph modeling and analysis techniques to assess the impact of node removal from a computing network and determine the impact that such removal has on the overall physical connectivity of the network. In one or more examples, a user or other entity can provide the system with a graph representation of a computing network, as well as specify the number of nodes to be removed (i.e., to simulate failure) to test the connectivity of the network. The system using these inputs can determine a worst-case scenario operating condition based on the inputs provided by the user, and can also assess the “network merit” which can represent a user-programmable definition that can represent a plurality desired types of connectivity.

    摘要: A degenerate four-wave mixing (DFWM) squeezed light apparatus includes one or more pump beams, a probe beam, a vapor cell, a repump beam, and a detector. The one or more pump beams includes an input power of no greater than about 150 mW. The vapor cell includes an atomic vapor configured to interact with overlapped pump and probe beams to generate an amplified probe beam and a conjugate beam. The repump beam is configured to optically pump the atomic vapor to a ground state and decrease atomic decoherence of the atomic vapor. The detector is configured to measure squeezing due to quantum correlations between the amplified probe beam and the conjugate beam. The one or more pump beams, the probe beam, and the repump beam are configured to generate two-mode squeezed light by DFWM with squeezing of at least 3 dB below shot noise.
