DESCRIPTION:Title: Indirect detection of gravitons through quantum entangl
 ement\n\nSpeaker: Sugumi Kanno (Kyushu University)\n\nAbstract: We propose
  an experiment that the entanglement between two macroscopic mirrors suspe
 nded at the end of an equal-arm interferometer is destroyed by the noise o
 f gravitons through bremsstrahlung. By calculating the correlation functio
 n of the noise\, we obtain the decoherence time from the decoherence funct
 ional. We estimate that the decoherence time induced by the noise of gravi
 tons in squeezed states stemming from inflation is approximately 20 second
 s for 40 km long arms and 40 kg mirrors. Our analysis shows that observati
 on of the decoherence time of quantum entanglement has the potential to de
 tect gravitons indirectly. This indirect detection of gravitons would give
  strong evidence of quantum gravity.\n\nhttps://indico.itp.ac.cn/event/93/
