  2. Quantum Sensing of Thermoreflectivity in Electronics - Hamza Ather

    Optical signals carrying quantum correlations can be used to illuminate objects, enabling in-principal quantum-enhanced sensing of the object or its properties. Here, we demonstrate quantum-enhanced temperature sensing of microelectronics using bright quantum optical signals. Relying on lock-in detection of thermoreflectivity, we measure the temperature change of a micro-wire induced by a current with an accuracy of better than 0.04 degrees averaged over 0.1 seconds. The results show a nearly...

  3. Long-range dipole-dipole interactions in nanophotonic media - Thrinadha Ashwin Kumar Boddeti

    Dipole-dipole interactions (DDIs) govern ubiquitous fundamental physical phenomena such as Casimir Forces, collective Lamb shifts, co-operative decay, and resonant energy transfer. The electromagnetic environment plays a crucial role in such interactions. We modify the nanophotonic environment in the vicinity of interacting emitters to enhance the strength and range of DDIS between an ensemble of emitters. Host: Dongyang Li

  4. Characterizing Thermal Emission From High-Temperature Radiators - Aashish Poudel

    High-temperature application materials are crucial for the future of the technological revolution. From increasing efficiency in energy harvesting to building thermal barrier coatings, materials that can withstand the impacts of high temperatures, and stay functionally, physically and chemically stable will become the fundamental building blocks in these fields. In this talk, I will discuss our experimental and theoretical endeavors in characterizing and optimizing materials'...

  6. Organic dye molecules as a platform for coherent light-matter interactions - Christian Lange

    A high-efficiency source of identical photons is the building block for many quantum technologies, and organic dye molecules have shown promise as a competitive platform for coherent light-matter interaction. In this talk, I will give an overview of solid state single-photon emission and discuss the applications of organic molecules in quantum science. Christian Lange is a Ph.D. student in the Dept of Physics and Astronomy. Host: Dongyang Li

  7. A general quantum algorithm for simulating open quantum dynamics - Zixuan Hu

    Open quantum dynamics describes the time evolution of a system interacting with an environment and has important applications in physical chemistry, materials science, applied physics, etc. Despite its importance, there are relatively few developments of quantum algorithms for simulating open quantum dynamics, and a main challenge is to design a general quantum algorithm for physical models beyond the 2-level system and Markovian systems. To this end, we present such a general quantum...

  8. Preparation of ultracold LiCs molecule for quantum applications - Saumitra Phatak

    Even though the ultimate theory that explains most of the universe is quantum mechanics, it is difficult to observe its effects on a macroscopic scale. First, we have to preserve the quantum nature of a system and understand it to an extent that we can exploit its unique properties, for applications like quantum computation or simulation. To this end, there are many model systems people are interested in, one of which is "ultracold molecules". Why ultracold? Why molecules? Why LiCs? How to...

  9. A Brief Introduction of Topological Quantum Computation - Bowen Yan

    A Brief Introduction of Topological Quantum Computation Abstract: I will start with basic ideas of quantum computation such as braiding, fusion space and some famous constructions of topological computational model. Moreover, I would talk about a recent dynamically generated model.

  10. Examining quantum states in high-dimensional systems - Alexandria Moore

    The quantum regime can be accessed on a variety of platforms, from superconducting qubits to trapped ions to photons. Quantum states are introduced in their most general form: high-dimensional qudits, which are of particular interest in photonic systems. Both polarization and frequency entangled photons are used to introduce various means of analyzing quantum states. Bell state analzers (BSA), quantum state tomography (QST), and quantum entanglement certification are covered. Recent work on...

  11. Atom-light interaction with cold atoms on a nanophotonic circuit - Xinchao Zhou

    Cold atoms trapped and interfaced with guided light in nanophotonic circuits form exciting new platforms for fundamental research on atom-light interactions and applications in quantum optics, quantum many-body physics and quantum networks. In this seminar, I will first talk about the experimental techniques about laser cooling and trapping by starting from the basics of atom-light interaction. In the second part, I will present experimental platform in our group about combining cold atoms...

  12. Superconducting Qubits, Hybrid Devices, and Circuit Architectures - Ramya Suresh

    Superconducting circuits are a popular platform for quantum computing and simulations, demonstrating several advantages such as improved coherence and robustness compared to trapped-ion, NV center, or ultracold-atom technologies. Custom circuits can be easily designed to mimic the physics of natural or artificial systems, making them relevant to a wide range of research fields. Over the years, qubit architectures have evolved towards improved scalability, lower losses, and improved...

  13. A Brief Overview of Quantum Communications - Yisheng Lei

    In this seminar, I will explain the working principles of quantum key distribution (BB84 & Ekert 91 protocols), quantum repeater (entanglement swapping, entanglement purification & quantum memory), Bell state measurement, quantum teleportation and also its recent experimental progress.
