The PI of our group will be teaching a specialized course on quantum entanglement in Spring 2021. This course is offered by the Department of Physics at Southern Illinois University to teach students the basic knowledge about quantum entanglement and its applications for quantum communication, quantum computing, and quantum sensing. The level of this course is appropriate for both graduate students and advanced undergraduates with engineering or science backgrounds.
Our recent work in collaboration with Suhail Zubairy on evaluating single-mode nonclassicality has been published in Phys. Rev. A. We use an operational resource-theoretic measure of nonclassicality of a single-mode quantum state to study the abilities of different classes of states for quantum-enhanced sensing. In particular, we find a class of states that are as good as squeezed vacuum states, which are important for certain sensing tasks including the laser interferometer gravitational-wave laboratory (LIGO) experiments. **10/09/2020**
Our recent work in collaboration with experimentalists Shaun Burd, Daniel Slichter, John Bollinger, and many others is available on arXiv. We have demonstrated over 3-fold enhancements of interaction strength between trapped-ion qubits using parametric amplification of the ion's external motion. Our idea can increase entangling-gate fidelities and can potentially reduce the energies used in coupling the trapped-ion qubits and the external motion. Our method could enable exploration of new parameter regimes and enhanced quantum information processing. **09/29/2020**
