From Heisenberg to Hubbard: An initial state for the shallow quantum simulation of correlated electrons
Bruno Murta, Joaquín Fernández-Rossier
The widespread use of the noninteracting ground state as the initial state for the digital quantum simulation of the Fermi-Hubbard model is largely due to the scarcity of alternati…
Quantum circuits to measure scalar spin chirality
L. I. Reascos, Bruno Murta, E. F. Galvão +1
The scalar spin chirality is a three-body physical observable that plays an outstanding role both in classical magnetism, characterizing non-coplanar spin textures, and in quantum…
Shallow unitary decompositions of quantum Fredkin and Toffoli gates for connectivity-aware equivalent circuit averaging
Pedro M. Q. Cruz, Bruno Murta
The controlled-SWAP and controlled-controlled-NOT gates are at the heart of the original proposal of reversible classical computation by Fredkin and Toffoli. Their widespread use i…
Density-matrix renormalization group: a pedagogical introduction
G. Catarina, Bruno Murta
The physical properties of a quantum many-body system can, in principle, be determined by diagonalizing the respective Hamiltonian, but the dimensions of its matrix representation…
