The 3.5-day Spring school will bring TCS researchers up to speed on the current excitement in quantum computing. The past decade had marked tremendous experimental progress, from one or two-qubit devices to dozens of qubits and more. What are the theoretical models for such devices, and what are their prospects? Can they be classically simulated, and if not, can they accomplish algorithmic speed-ups? What are the obstacles to full-blown fault-tolerant quantum computation? And what does all this tell us about complexity theory, cryptography, and quantum information?
What are the latest developments in quantum information science and computation?
What are the current challenges in algorithms, hardware, and technology transition to engineering applications?
NASA brought word leading scientist and industry leaders come together at Quantum Computing workshop to answer these questions and discuss future of the Quantum Computers.
Surface plasmons (SPs) are evanescent waves generated through the collective oscillations of electrons at a metal/dielectric interface under optical excitation. Due to the strong light-electron coupling and near-field nature, surface plasmons offer: (1) the opportunity for sub-wavelength spatial confinement of optical waves is enabled; and (2) giant local field enhancement of optical waves is permitted. These unique attributes lead to the long-envisaged optical circuits, and allowed breakthroughs in the generally termed “plasmonics” . For example, in the realizations of optical nano-...
The mission of the Kaufman Foundation is to support fundamental research in biology, chemistry, and physics at Pennsylvania institutions of higher education. The Kaufman Foundation grants to institutes of higher learning in Pennsylvania for scientists pursuing research that explores their field’s essential questions and/or crosses disciplinary boundaries. Mr. Kaufman believed in the potential impact of fundamental, curiosity-driven science and the strength of working across interdisciplinary boundaries. He also recognized the importance of supporting early and mid-career scientists, while acknowledging the major accomplishments achieved after a lifetime of high-impact contributions. When he died in 2010, Charles Kaufman, a respected chemical engineer, left $50 million to The Pittsburgh Foundation of which $40 million is earmarked for continuing his life-long commitment to scientific research with the potential to improve human life. Since 2013, and including 2017, the Foundation has awarded 43 grants totaling $9.1 million.
Secretary of the Air Force Heather Wilson announced in September 2017 inception of the "S&T Strategy 2030" study. The study's objective is to update the Air Force methods for conducting research and development to meet the projected national security challenges of 2030.
Secretary Wilson appointed the Air Force Research Laboratory (AFRL) to lead this strategy development. The Air Force's goals for the study are:1. Evaluate technical approaches and focus areas to advance the Air Force's mission through R&D; and 2. Improve Air Force processes and organizational structures to manage early stage research.
In recent decades, a large scientific effort has focused on harnessing spin transport for providing insights into novel materials and low-dissipation information processing. We introduce single spin magnetometry based on nitrogen-vacancy (NV) centers in diamond as a new and generic platform to locally probe spin chemical potentials which essentially determine the flow of spin currents. We use this platform to investigate magnons in a magnetic insulator yttrium iron garnet (YIG) on a 100 nanometer length scale. We demonstrate that the local magnon chemical potential can...
The chiral spin textures are a consequence of the anti-symmetric exchange interaction, which presents in the material systems with broken inversion symmetry, such as B20FeGe. This interaction enables chiral magnetic order, including topologically non-trivial magnetic skyrmions, which display rich new magnetic phenomena and require low critical current densities to manipulate. This makes magnetic skyrmions a promising platform for power-efficient spintronics applications. Therefore, a deeper understanding of the static and dynamic magnetic properties of these materials...
