Summary
Many disruptive information technologies (such as quantum technologies and 6G communication) have been emerging as critical enablers to significantly promote human wellbeing, such as ultra-fast computers and mobile Internet. However, due to civilized development and growing volumes of data, it has aroused higher requirements of data-processing power and wireless communication efficiency. Exploring new approaches to improve the performance in advanced information technology is a destination that scientists have been constantly pursuing. One promising technology for achieving such goals in a spatially and temporally controllable manner utilizes an artificially engineered array of active elements, known as space-time metasurfaces. This project will use one of two-dimensional (2D) materials (graphene) to design and fabricate space-time metasurface, addressing a key question in the fields of quantum information and photonics: how to dynamically manipulate the quantum states of entangled photons or nonlinear light based on different degree of freedom, such as frequency and polarization. The key objective of the project is to build a practical prototype of space-time quantum metasurfaces based on graphene for the first time. This project will focus on three different objectives: theoretical design of time-modulated algorithm and optimized space distribution, fabrication of space-time metasurfaces with gated-tuned graphene nanopatterns, and quantum imaging applications of space-time metasurfaces. The multidisciplinary nature of the project is strong, involving a combination of well developed optics, information science, quantum technology, 2D materials and nanofabrication. This proposal includes both the transfer of knowledge to the host institution and the training of the candidate in new advanced techniques. Results have the potential capacity to increase the competitiveness of quantum technology and nanophotonics.

Original description
Many disruptive information technologies (such as quantum technologies and 6G communication) have been emerging as critical enablers to significantly promote human wellbeing, such as ultra-fast computers and mobile Internet. However, due to civilized development and growing volumes of data, it has aroused higher requirements of data-processing power and wireless communication efficiency. Exploring new approaches to improve the performance in advanced information technology is a destination that scientists have been constantly pursuing. One promising technology for achieving such goals in a spatially and temporally controllable manner utilizes an artificially engineered array of active elements, known as space-time metasurfaces. This project will use one of two-dimensional (2D) materials (graphene) to design and fabricate space-time metasurface, addressing a key question in the fields of quantum information and photonics: how to dynamically manipulate the quantum states of entangled photons or nonlinear light based on different degree of freedom, such as frequency and polarization.
