Programmable Quantum Simulation in Carbon Nanotube Exciton-Polariton at Room Temperature

Quantum simulation is an analog quantum computation, one of the quantum computing streams, which mimics a real system in a small device to solve physics problems, in the context of the Hamiltonian engineering. There are several quantum simulation platforms, trapped-ion simulators, ultracold atom simulators, and superconducting simulators. Exciton-polariton is relatively easy to access to the measurements and obtain the results. Amongst polariton cases, strongly coupled interaction between a photon and matter, microcavity exciton-polariton is normally employed, which comes from a miniaturized Fabry-Pérot cavity to capture photons to couple with gain media. Conventional gain media, III-V materials, have been investigated with outstanding results, but cryogenic temperature is required due to the small binding energy and high-cost fabrication technique. For the room temperature operation, gain media of large-bandgap semiconductors, organic materials, transition metal dichalcogenides (TMDCs), and perovskites are studied. Here we introduce single-walled carbon nanotubes (SWCNTs) as SWCNTs are known to have high binding energy with selective energy bandgaps depending on the chirality. Furthermore, we would like to introduce programmable lattices with laser profile engineering with a spatial light modulator in order to tackle a variety of physics problems.
