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.

Mesoscopic systems as coherent control elements
Summary Mesoscopic systems provide a new tool for quantum systems design. In particular, they are enabling of robust quantum control. Here “mesoscopic system” refers to a connected network where each element, if studied alone, would be a quantum bit. The network is too big to be treated fully quantum mechanically. We do not have individual […]

Materials for Majorana-based Topological Qubits
Summary Topological qubits offer a novel pathway to scalable quantum computing by simultaneously allowing for ease of coupling between qubits and strong decoupling of qubits from noise and dissipation. The most promising direction explores the topologically induced protection of theoretically predicted exotic quasiparticles, the so-called Majorana Zero Modes or MZMs. To-date MZMs, which follow […]

Magnetoelectric Coupling in New Composite Multiferroic Nanostructures as High-Density Quantum Multistate Memory Elements
Summary Magnetoelectric multiferroics are materials that exhibit correlated ferroelectric and ferromagnetic properties (i.e., a magnetoelectric effect). The resulting ability of these materials to simultaneously store data in electric polarization and magnetic moment could increase data storage density and data processing speed while reducing energy consumption. This project aims to design and fabricate new composite multiferroic […]
