    Guide to the Alan Bersin papers

    Get PDF
    The Alan Bersin papers consist of records collected by Bersin during his tenure as the Superintendent of San Diego City Schools and the Secretary of Education for the State of California. The vast majority of the records are in the form of correspondence, memoranda, meeting minutes, reports, and newspaper articles. These records delve into the workings of Bersin\u27s office, planning behind such programs as the Blueprint for Student Success, the Institute for Learning, Special Education, and Charter Schools. Correspondence, news articles, and court cases document reaction to those programs from the public, labor unions, and the San Diego Board of Education. Records also include meeting minutes and meeting preparatory material for the Board of Education as well as correspondence between Bersin and Board members. Also included are grant proposals and grant reports for a variety of Foundations, as well as legislative records to assist funding San Diego City Schools. The Alan Bersin papers also consist of California-wide education records collected during his tenure as Secretary of Education. Records cover topics such as standards, testing, curriculum, facilities, funding, charter schools and implementation of No Child Left Behind. Transition materials related to Bersin\u27s time as Superintendent of San Diego City Schools, as well as letters from the public regarding Bersin\u27s successes and failures, are also included.

    Leading Learning & Development (L&D): ELE Leader Members Test-Drive Josh Bersin Academy

    Get PDF
    ELE would like to recruit members to create a 5-week cohort to experience semi-synchronous collaborative learning. As learning professionals, we’re faced with a largely new landscape and increasing demand for our work, as organizations begin to see why learning is now a business imperative. The Leading L&D Program by Nomadic Learning explores these changes and offers tools for developing new strategies that align with what both employees and organizations need to thrive. In the Leading L&D program, learners will get hands-on, practical guidance and time-tested wisdom from peers, and will explore together: What is the benefit of learning in cohorts rather than individually? How can L&D serve as a response to this period of ongoing uncertainty? What are the benefits of shifting our thinking away from learning systems and toward a culture of learning? How can we measure the effectiveness of learning with clear, impactful data? Pre Read: Key takeaways on how the Great Resignation is changing talent acquisition, internal mobility, and L&D.

    Threshold Order: Bilateral Law Enforcement and Regional Public Safety on the U.S./Mexico border

    Get PDF
    The Mexican/United States border region presents a study in contrast and ambivalence in both countries as well as between them. The border marks the collision of international boundaries--the beginning and end of nations as well as a merger of them. It composes a binational corridor and channel where currents of free trade, family ties, migration, cultural exchange, illegal firearms, and drug trafficking boil most actively in tandem. Cross-border perspectives and organizations that promote and share a sense of regional identity are, therefore, increasingly essential to a satisfactory working relationship between the United States and Mexico

    A Quantum Router Architecture for High-Fidelity Entanglement Flows in Quantum Networks

    Full text link
    The past decade has seen tremendous progress in experimentally realizing the building blocks of quantum repeaters. Repeater architectures with multiplexed quantum memories have been proposed to increase entanglement distribution rates, but an open challenge is to maintain entanglement fidelity over long-distance links. Here, we address this with a quantum router architecture comprising many quantum memories connected in a photonic switchboard to broker entanglement flows across quantum networks. We compute the rate and fidelity of entanglement distribution under this architecture using an event-based simulator, finding that the router improves the entanglement fidelity as multiplexing depth increases without a significant drop in the entanglement distribution rate. Specifically, the router permits channel-loss-invariant fidelity, i.e. the same fidelity achievable with lossless links. Furthermore, this scheme automatically prioritizes entanglement flows across the full network without requiring global network information. The proposed architecture uses present-day photonic technology, opening a path to near-term deployable multi-node quantum networks.Comment: 8 pages, 4 figure

    Super-resolution localization and readout of individual solid-state qubits

    Thesis: S.M., Massachusetts Institute of Technology, Department of Electrical Engineering and Computer Science, 2018.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (pages 67-74).A central goal in quantum information science is to establish entanglement across multiple quantum memories in a manner that allows individual control and readout of each constituent qubit. In the area of solid state quantum optics, a leading system is the negatively charged nitrogen vacancy center in diamond, which allows access to a spin center that can be entangled to multiple nuclear spins. Scaling these systems will require the entanglement of multiple NV centers, together with their nuclear spins, in a manner that allows for individual control and readout. Here we demonstrate a technique that allows us to prepare and measure individual centers within an ensemble, well below the diffraction limit. The technique relies on optical addressing of spin-dependent transitions, and makes use of the built-in inhomogeneous distribution of emitters resulting from strain splitting to measure individual spins in a manner that is non-destructive to the quantum state of other nearby centers. We demonstrate the ability to resolve individual NV centers with subnanometer spatial resolution. Furthermore, we demonstrate crosstalk-free individual readout of spin populations within a diffraction limited spot by performing resonant readout of one NV during a spectroscopic sequence of another. This method opens the door to multi-qubit coupled spin systems in solids, with individual spin manipulation and readout.by Eric Bersin.S.M
