Development of room-temperature exciton-polariton quantum simulator

This MITACS project between the University of Waterloo (UW, host supervisor: Prof. Na Young Kim) and Yonsei University (YU, home supervisors: Prof. Jong-Souk Yeo and Prof. Chae-Yeun Park) aims to develop a room-temperature exciton-polariton quantum simulator. The room-temperature system can contribute to solving a complex many-body problem, since it does not require cryogenic cooling that limits the scalability of quantum information processors. The exciton-polariton quantum simulator is a solid-state platform that can be fabricated using conventional deposition/lithography techniques. Since the exciton-polariton is a bosonic quasiparticle that also interacts strongly with matter, both bosonic and fermionic dynamics can be emulated. The room-temperature operation can be demonstrated by utilizing transition metal dichalcogenides that have exciton binding energies larger than 25.9 meV. We plan to theoretically understand and design the simulator to describe the Bose-Hubbard Hamiltonian, fabricate and characterize a unit exciton-polariton system, and correlate the experimental results with the defined Hamiltonian. This project will be successfully conducted leveraging the UW’s outstanding expertise in quantum simulation and YU’s extensive experience in nanomaterials engineering. The collaboration between the UW and YU, which was officially initiated by signing a Memorandum of Understanding (MOU), will be further strengthened and expanded thanks to the MITACS project.
