Hamiltonian Determination with Restricted Access in Transverse Field Ising Chain
Mohammad Ali Fasihi, Shu Tanaka, Mikio Nakahara +1
We propose a method to evaluate parameters in the Hamiltonian of the Ising chain under site-dependent transverse fields, with a proviso that we can control and measure one of the e…
Estimation of Spin-Spin Interaction by Weak Measurement Scheme
Yutaka Shikano, Shu Tanaka
Precisely knowing an interaction Hamiltonian is crucial to realize quantum information tasks, especially to experimentally demonstrate a quantum computer and a quantum memory. We p…
Entanglement in valence-bond-solid states on symmetric graphs
Hosho Katsura, Naoki Kawashima, Anatol N. Kirillov +2
We study quantum entanglement in the ground state of the Affleck-Kennedy-Lieb-Tasaki (AKLT) model defined on two-dimensional graphs with reflection and/or inversion symmetry. The g…
