We propose a theoretical scheme to study the Lee-Huang-Yang (LHY) quantum correction on the interference of two expanding Bose-Einstein condensates (BEC). The key is to consider a long-term expanding condensate whose wave function mimics the dynamic Gaussian wave. This enables to solve analytically the wave function at an earlier time when the LHY correction is active. Based on the GPE approach, we then perform the simulations for the interference, and a good agreement with the theory has been achieved. Our results suggest that interference might be a good candidate to identify the LHY correction in a BEC system.
