Symmetry-adapted sample-based quantum diagonalization: Application to lattice model
Kosuke Nogaki, Steffen Backes, Tomonori Shirakawa +2
We present a symmetry-adapted extension of sample-based quantum diagonalization (SQD) that rigorously embeds space-group symmetry into the many-body subspace sampled by quantum har…

Bosonic Nevanlinna Analytic Continuation
Kosuke Nogaki, Hiroshi Shinaoka
Analytical continuation (AC) connects theoretical calculations and experimentally measurable quantities. The recently proposed Nevanlinna AC method is capable of accurately reprodu…
