    Summary

     

    As part of an effort to improve quantum sensing, we are developing new semiconductor p-n junctions and designing novel nanowire arrays that have the potential to significantly enhance the ability to detect light at the single photon level over an unprecedented wavelength range from the ultraviolet to infrared. We are working to demonstrate high-speed single-photon detection with broadband high efficiency from the visible to near-infrared range (450-900 nm), with no need for cryogenic cooling. In the future, it will be possible to extend detection into the infrared wavelengths by changing the semiconductor material from InP to InGaAs. Applications resulting from this work can improve a broad range of technologies. These include quantum computing, quantum cryptography, single-molecule fluorescence spectroscopy, laser remote sensing (LIDAR), and single oxygen luminescence for cancer treatment dose monitoring.

    Plasmon Control of Quantum States in Semiconductor Nanocrystals

    Summary   Thanks to the light-induced collective oscillations of free charges at the boundary between a conducting material and a dielectric, known as surface plasmon resonance, metallic nanostructures can exhibit strong light absorption and scattering. The sensitivity of these resonances to the local environment and shape of the metallic structures allows them to be used, […]

    A Reformulation of Quantum Game Theory

    Summary Classical game theory – conducted at the interface between economics and computer science – has found applications in topics ranging from networking and security to online markets. Despite over 20 years of research into connections between game theory and quantum information, we have yet to see any significant implications of quantum information when applied […]

    Tuning Spin-Exchange Interactions in Low-Dimensional Metal Halide Perovskites: A New Class of Semiconductor Quantum Materials

    Summary  Leakage current in electronic components is one of the limiting factors for the performance of conventional computers which use charges and currents as physical information carriers. Spintronics offers an alternative by using electron spin for information transfer, processing and storage, enabling the design of non-volatile computer memory and more energy-efficient electronic devices. In this […]
