Spectral functions on a quantum computer through system-environment interaction
Etienne Granet, Ramil Nigmatullin, David T. Stephen +1
Spectral functions measured with angle-resolved photoemission spectroscopy (ARPES) provide key insight to elucidate the band structure of materials. Comparison with theory requires…
Superconducting pairing correlations on a trapped-ion quantum computer
Etienne Granet, Sheng-Hsuan Lin, Kevin Hémery +31
The Fermi-Hubbard model is the starting point for the simulation of many strongly correlated materials, including high-temperature superconductors, whose modelling is a key motivat…
Density Classification with Non-Unitary Quantum Cellular Automata
Elisabeth Wagner, Federico Dell'Anna, Ramil Nigmatullin +1
The density classification (DC) task, a computation which maps global density information to local density, is studied using one-dimensional non-unitary quantum cellular automata (…
Experimental Demonstration of Break-Even for the Compact Fermionic Encoding
Ramil Nigmatullin, Kevin Hemery, Khaldoon Ghanem +8
The utility of solving the Fermi-Hubbard model has been estimated in the billions of dollars. Digital quantum computers can in principle address this task, but have so far been lim…
