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…
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…
Gutzwiller wave function on a digital quantum computer
Bruno Murta, Joaquín Fernández-Rossier
The determination of the ground state of quantum many-body systems via digital quantum computers rests upon the initialization of a sufficiently educated guess. This requirement be…
Berry Phase Estimation in Gate-Based Adiabatic Quantum Simulation
Bruno Murta, G. Catarina, J. Fernandez-Rossier
Gate-based quantum computers can in principle simulate the adiabatic dynamics of a large class of Hamiltonians. Here we consider the cyclic adiabatic evolution of a parameter in th…
