Local symmetries and extensive ground-state degeneracy of a 1D supersymmetric fermionic chain
Shuyu Zhang, Hiroki Sukeno, Kazuki Ikeda +1
We study a D supersymmetric (SUSY) hard-core fermion model first proposed by Fendley, Schoutens, and de Boer [Phys. Rev. Lett. 90, 120402 (2003)]. We focus on the full Hilbert s…
Constant-depth preparation of matrix product states with adaptive quantum circuits
Kevin C. Smith, Abid Khan, Bryan K. Clark +2
Adaptive quantum circuits, which combine local unitary gates, midcircuit measurements, and feedforward operations, have recently emerged as a promising avenue for efficient state p…
Bulk and boundary entanglement transitions in the projective gauge-Higgs model
Hiroki Sukeno, Kazuki Ikeda, Tzu-Chieh Wei
In quantum many-body spin systems, the interplay between the entangling effect of multi-qubit Pauli measurements and the disentangling effect of single-qubit Pauli measurements may…
Kennedy-Tasaki transformation and non-invertible symmetry in lattice models beyond one dimension
Aswin Parayil Mana, Yabo Li, Hiroki Sukeno +1
We give an explicit operator representation (via a sequential circuit and projection to symmetry subspaces) of Kramers-Wannier duality transformation in higher-dimensional subsyste…
Measuring Topological Field Theories: Lattice Models and Field-Theoretic Description
Yabo Li, Mikhail Litvinov, Tzu-Chieh Wei
Recent years have witnessed a surge of interest in performing measurements within topological phases of matter, e.g., symmetry-protected topological (SPT) phases and topological or…
