Distribution Complexity of Electronic Structure Simulations on Quantum Supercomputers
Jason Necaise, Namit Anand, Gaurav Gyawali +3
Efficient simulation of strongly-interacting fermionic systems on quantum processing units (QPUs) is a challenging task due to nonlocal mode entanglement generation. However, it is…
Group Theory and Representation Theory for Identical Particles
James Daniel Whitfield
Few, if any, applications of quantum technology are as widely known as the quantum simulation of quantum matter. Consequently, many interesting questions have been sparked at the i…
Gaussianity and Simulability of Cliffords and Matchgates
Andrew M. Projansky, Jason Necaise, James D. Whitfield
Though Cliffords and matchgates are both examples of classically simulable circuits, they are considered simulable for different reasons. The celebrated Gottesman-Knill explains th…
Fermionic Mean-Field Theory as a Tool for Studying Spin Hamiltonians
Thomas M. Henderson, Brent Harrison, Ilias Magoulas +5
The Jordan--Wigner transformation permits one to convert spin operators into spinless fermion ones, or vice versa. In some cases, it transforms an interacting spin Hamiltonia…
