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…

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…

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…
