This paper demonstrates that a network of optical energy transfer between quantum nanostructures mediated by optical near-field interactions, occurring at scales far below the wavelength of light, could be utilized for solving constraint satisfaction problems (CSPs). The optical energy transfer, from smaller quantum dots to larger ones, a quantum stochastic process, depends on the existence of resonant energy levels between the quantum dots or a state-filling effect occurring at the larger quantum dots. Such a spatial and temporal mechanism yields different evolutions of energy transfer patterns in multiquantum-dots systems. We numerically demonstrate that optical energy transfer processes can solve a CSP. We consider such an approach pave the way for a novel computation paradigm beyond those of conventional optical or quantum computations.
