Indirect detection of gravitons through quantum entanglement

We propose an experiment that the entanglement between two macroscopic mirrors suspended at end of equal-arm interferometer is destroyed by noise gravitons through bremsstrahlung. By calculating correlation function noise, we obtain decoherence time from functional. estimate induced in squeezed states stemming inflation approximately 20 seconds for 40 km long arms and kg mirrors. Our analysis shows observation quantum has potential to detect indirectly. This indirect detection would give strong evidence gravity.
