The new study was published in Science Bulletin. Four scholars from Tsinghua University, Li Hang, Gao Xun, Xin Tao and Long Guilu, collaborated with a scholar from Southern University of Science and Technology, Yung Man-Hong. In the study, they solved two-fold and three-fold Forrelation problems in nuclear spins and controlled the spin fluctuation to within a threshold value using a set of optimized GRAPE pulse sequences. It is widely believed that quantum computers have an advantage over classical computers in many computational problems. In the black-box model, many quantum algorithms exhibit quantum speedups. This raises a question: Within the black-box model, just how large a quantum speedup is possible? Specifically, in query complexity, can we find the largest separation between classical and quantum query complexities? Two years ago, Aaronson and Ambainis introduced a new property-testing problem called Forrelation, which determines whether one Boolean function is highly correlated with the Fourier transform of another Boolean function. And they showed that it gave the largest quantum black-box speedup yet known. Professor Long Guilu and his collaborators designed a quantum circuit for implementing multi-fold Forrelations. They realized the two-fold and three-fold case of Forrelations on a nuclear magnetic resonance spectrometer by measuring the value of Forrelation to determine if it was larger than 3/5 or the absolute value was less than 1/100. This is the first experimental realization of the Forrelation problem reported in literature. Their results are shown in figure 1. Professor Long Guilu, who directed the experiment, says, "One of the difficulties is achieving a high fidelity of the final states, since the value of Forrelation is highly sensitive to the measurement. To control the error within a threshold value, we utilized an optimized gradient ascent pulse engineering technique instead of a composite pulse sequence of hard pulses and J-coupling evolutions." Professor Yung Man-Hong points out the future development of their work: "All the quantum algorithms are implemented on a three-qubit quantum information processor, which may not present the power of quantum computation over classical computation due to the present experimental techniques. However, this prototype experiment indicates that we may gain quantum supremacy in relatively simple quantum devices in the near future."

The project will apply a tested methodological approach--a multi-metric approach to assess the impact of STEM instructional multimedia on undergraduate teaching and learning-- to the subject matter of electronic health records (EHR). The project deploy three comprehensive multimedia case studies that introduce undergraduate STEM students to electronic health records and assess the effect of this approach on student learning, including impact on higher order cognitive skills. Three constructs and criteria will be used to assess students actual learning: 1) Learning-Driven factor, 2) Content-Driven factor, and 3) Higher-Order Cognitive Skills factor. Three inter-related qualitative and quantitative matrices will be developed to assess students perceived learning (Perceived Learning Matrix), actual learning (Actual Learning Outcome Matrix), and learning processes (Learning Process Matrix). The innovative multimedia instructional approach developed in this project is expected to give students first-hand observational experience of EHR operations and can be used to teach other information technology topics where visualization is very important as opposed to traditional text book lecture on emerging technology issues.

This award is one component of a collaborative effort to fund the Laser Interferometer Gravitational-wave Observatory (LIGO) Science Education Center Partnership between Southern University in Baton Rouge (SUBR), LA, the LIGO Livingston site in Livingston, La, through the Baton Rouge Area Foundation (BRAF), and the Exploratorium. The managing institution for LIGO itself is California Institute of Technology. The project is the continuation of the LIGO Science Education Center Partnership focused on scientific outreach to the general public, teacher training, and teacher education focused on LIGO activities in Louisiana. A previous award helped create the SEC building, with a classroom and a large exhibit hall, with exhibits developed by the Exploratorium and staffed by SUBR student docents and a (separately funded) professional staff. The multilayered partnership of HBCUs, a cutting edge research facility and a renowned informal science center created a model for future partnerships. With the expansion of this partnership the model is extended, and research on the effects of these extensive partnerships can provide information for future attempts at leveraging the resources of research laboratories for educational purposes.
This project will use the LIGO-SEC Partnership to amplify and nurture a Science, Technology, Engineering, Education and Mathematics (STEEM) pipeline that taps into under-represented audiences and engages them in techniques that encourage students to advance their education in STEEM fields. The docent program and the teacher programs will increase participation of under-represented audiences within the STEEM fields. The docent program will train between sixty and eighty under-represented STEEM majors to become community ambassadors in conjunction with LIGO Science Education Centers outreach program, and the docents will interact with between 12,500 and 5,000 participants. The teacher professional development activities target high-need areas in New Orleans and Baton Rouge. The activities will develop around 250 teachers familiarity with engineering design processes and underlying science concepts. These teachers will create and build interactive science activities to use in the classroom to engage with students. Graduate students will conduct new research in the use of inquiry and informal science methods within the formal (School) and informal (LIGO-SEC) environments. The graduate students dissertations will contribute to the literature on Informal Science Education. The project is guided by an on-going evaluation.

Gas Electron Multiplier (GEM) based fluorescence X-ray gas detector is an indispensable tool for characterizing dilute elements of 10 parts per million (ppm) and below using X-ray Fluorescence Spectroscopy (XFS). When atoms of a dilute element in a sample are excited by a tuned energy synchrotron radiation beamline, they emit weak X ray fluorescence signal. The fluorescence X-ray signal has low penetrating power, is severely attenuated by air, and ionizes few electrons in an ionization chamber. Detecting the small primary electronic charge signal is very difficult using conventional fluorescence detectors with low signal to noise (S/N) ratio. To improve the S/N ratio, we propose to use a single and multiple gas electron multiplier (GEM) to amplify the ionized primary electronic charge without noise in an ionization chamber. The amplified charge will enhance the S/N ratio, improve the detection, analysis, and facilitate to characterize dilute samples. Conventional fluorescence detectors are affected by micro phonic vibrations, temperature, light, have small S/N ratio, and occasional gain drift with time. The GEM based detector is rigid, gas leak proof, allows cascaded multiple GEMs for gain control, avoids spark discharge from high fields due to a single GEM, has noise free electron amplification, and allows measuring fast signal with high rate capability. The detector has flexible window size for x-ray entrance, flexible solid angle of acceptance, variable GEM dimension, uses multiple gas mixtures, operates at atmospheric pressure, and at room temperature. This project is performed in collaboration with Morgan State University, Brookhaven National Laboratory (BNL), and Southern University Baton Rouge to enhance, educate and train minority students in building new detectors that will be used at the National Synchrotron Light Source (NSLS) and at other national and international laboratories.
Detecting dilute elements of ten parts per million and below, in natural or manufactured samples requires a high signal to noise (S/N) ratio detector. When a dilute element under test is excited by a tuned energy synchrotron beamline, it releases a characteristic fluoresce X-ray that is used to ionize a noble gas producing a charge signal. This primary charge signal is too small to be detected because of the large noise interference introduced by electronic amplifiers. The proposed detector uses a gas electron multiplier (GEM) that multiplies or amplifies the small primary charge created by the dilute element fluorescence X-ray. The GEM amplified charge signal amplitude far exceeds the level of the noise produced by the electronic amplifiers providing a high S/N ratio. This will allow better detection and characterization of dilute elements in various samples. This project is performed in collaboration with Morgan State University, Brookhaven National Laboratory (BNL), and Southern University Baton Rouge to enhance, educate, and train minority students in building new detectors that can be used at the National Synchrotron Light Source (NSLS) and at other national and international laboratories.

Smaller universities including Historically Black Colleges and Universities (HBCU), Minority Serving Institutions (MSI), Hispanic Serving Institutions (HSI) and American Indian Serving Engineering Institutions (AISEI) often lack resources required to prepare faculty for highly competitive and critically important STEM education research. As a result, many of the faculty are handicapped when they attempt to acquire funding to investigate and implement new educational ideas. Furthermore, this makes the adoption of modern pedagogy and new STEM education ideas difficult at these institutions. Ultimately, it is the students who suffer because they may not receive the benefits of the newest STEM education discoveries.
This project is assisting critical schools to develop their STEM faculty so they are better able to compete with larger, resource richer institutions. Stronger STEM faculty will translate to stronger universities and to more and stronger STEM graduates. The project builds on prior research and incorporates previously successful faculty development activities. The work is also informed by an elite group of university deans who provided input to the project design. Outcomes are being assessed using an external evaluator and will be widely disseminated.

The Historically Black Colleges and Universities - Undergraduate Program (HBCU-UP) provides support to undertake an institutional self-analysis in preparation for a Broadening Participation Research Center. Broadening Participation Research Centers are expected to serve as a national hub for the rigorous study and broad dissemination of the critical pedagogies and culturally sensitive interventions that contribute to the success of HBCUs in educating African American STEM undergraduates. The project at Southern University seeks to investigate identified contributory factors envisioned to support advancing diversity and inclusion through global research engagement as a promising interventional approach with the potential to change the culture of science, technology, engineering and mathematics (STEM) education for underrepresented minority students.
The project seeks to frame a new model for transformative STEM teaching and learning that advances science and societal well-being through the 21st century; enhance the research knowledge base to better understand the multidimensionality of underlying issues affecting STEM workforce disparities; and incorporate research, education, outreach, and knowledge transfer into an integrated learning ecosystem that will inform STEM education practices and interventions. To address this grand challenge, the projects activities and strategies are designed to investigate the viability of global translation in: creating shareable knowledge; educating a new generation of scholars, practitioners, innovators, entrepreneurs, and leaders; positively impacting the inclusion of disproportionately represented diverse minorities in the STEM workforce; and developing practical solutions to the most pressing environmental, economic, and social challenges of sustainability. The project will be guided by formative and summative evaluation.
