Preparing Valence-Bond-Solid states on noisy intermediate-scale quantum computers
Bruno Murta, Pedro M. Q. Cruz, J. Fernández-Rossier
Quantum state preparation is a key step in all digital quantum simulation algorithms. Here we propose methods to initialize on a gate-based quantum computer a general class of quan…

One-to-one correspondence between thermal structure factors and coupling constants of general bilinear Hamiltonians
Bruno Murta, J. Fernández-Rossier
A theorem that establishes a one-to-one relation between zero-temperature static spin-spin correlators and coupling constants for a general class of quantum spin Hamiltonians bilin…
