We have studied the interferometric sensitivity for gravitational wave detection explicitly including the photodetector efficiency. We show that the sensitivity is very strongly affected by non-ideal photodetector efficiency when we inject a squeezed signal, as compared to the ordinary vacuum case. Quantum limits and resonance are also discussed for short time detections.
