"Reference-State Error Mitigation... correcting for errors due to noise... solving same problem on both conventional and quantum computer... reference state simpler description molecule than originally solved quantum computer and conventional computer both solve quickly... comparing results exact estimate error caused by noise... difference correct the solution when run quantum processor... calculating the intrinsic energy of small example molecules such as hydrogen and lithium hydride"
