In tensor network methods, MPOs allow for computation of local observables, which is particularly useful for algorithms like DMRG. Since most MPOs are nonunitary, current state-of-the-art methods favour block-encoding for implementation. However, utility is limited by circuit depth and ancilla overhead on current hardware. We propose a new, more hardware efficient implementation of Hermitian MPOs and show that both circuit width and depth are significantly reduced for the Transverse Field Ising Model.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>We are pleased to welcome back Naivasha Williams, formerly a PQM MPhys student, to report on her PhD research in Prof. Andrew Green&#8217;s group at the London Centre for Nanotechnology, UCL.
