Abstract

Recently both experimental and theoretical works have shown optically addressable molecular spins could have a great potential for quantum information processing. Experimental works such as spin qubit initialisation, coherence control, and readout suggest spin-bearing molecules can be a great candidate for quantum computing. Time-resolved electron spin resonance on molecular radicals at high temperature indicates molecular spins could be the cornerstones for high-temperature quantum gate operations, thus overcoming the low-temperature technical barrier for maintaining quantum circuits effectively. In this proceeding, we have discussed the potential of molecular materials, especially two dimensional molecular network, for optically driven quantum information processing, in combination with nanophotonic devices. Although this is only a theoretical proposal, we hope this can be inspiring for the future development of quantum computing. Obviously there are many difficulties on the way forward, such as single spin readout in molecules, optimal design of molecular networks and corresponding optical instruments, which are be solved in the future.
