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…
