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…
Putting fermions onto a digital quantum computer
Riley W. Chien, Mitchell L. Chiew, Brent Harrison +8
Quantum computers are expected to become a powerful tool for studying physical quantum systems. Consequently, a number of quantum algorithms for studying the physical properties of…
QB Ground State Energy Estimation Benchmark
Nicole Bellonzi, Joshua T. Cantin, Mohammad Reza Jangrouei +14
Ground State Energy Estimation (GSEE) is a central problem in quantum chemistry and condensed matter physics, demanding efficient algorithms to solve complex electronic structure c…
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…
A Sierpinski Triangle Fermion-to-Qubit Transform
Brent Harrison, Mitchell Chiew, Jason Necaise +3
In order to simulate a system of fermions on a quantum computer, it is necessary to represent the fermionic states and operators on qubits. This can be accomplished in multiple way…
