    Summary

     

    The Quantum Encryption and Science Satellite provides a platform to develop and deploy quantum sensing and metrology via photonic channels. This project will build upon ‘free-space’ quantum communication technology and explore new approaches and methods to advance two primary applications: quantum-enhanced telescopes, and spectroscopic sensing for methane detection in the atmosphere. For the telescope application we will develop novel methods for imaging using multi-photon interference, such as in long-baseline telescopes. For greenhouse gas monitoring, we will perform a detailed analysis of a two-photon sensing setup, prepare a feasibility study on trace gas metrology using quantum communication channels, and move the demonstration from in-lab to outdoors, and finally to field deployment (two optical telescopes). This project also supports long-distance quantum communication by providing a framework and justification for quantum repeater networks. We expect these advancements will find wider application in enhanced performance of atmospheric environmental monitoring and imaging.

    Quantum Light Sources Based on Deterministic Photon Subtraction

    Summary   This project develops new sources of light that utilize quantum entanglement to enhance imaging resolution and detection. We aim to go beyond simple photon pairs and advance our understanding and control of new quantum states of light. Our approach uses deterministic single-photon subtraction (removing of a specific photon from a pulse of light) […]

    Quantum Dynamics of Cavity Interactions with Spin Ensembles

    Summary   High quality factor cavities can be powerful control elements for ensembles of spins, enabling unitary control as well as on demand cooling. They can also be used to couple two otherwise non-interacting ensembles. The goal of the project is to explore the physics and engineering of such systems both theoretically and experimentally. The laboratory contains a […]

    Novel Superconducting Qubits for Error-Corrected Processors

    Summary In this project, we develop novel superconducting qubits for error-corrected processors to enable large-scale quantum computing. Our design efforts will specifically target error-corrected architectures through a variety of paths. Possible features will include built-in parity measurements and the use of bosonic codes, such as Fock state and Cat codes, as our starting focus. Early […]

    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 […]
