Optimizing fermionic Hamiltonians with classical interactions
Maarten Stroeks, Barbara M. Terhal, Yaroslav Herasymenko
We consider the optimization problem (ground energy search) for fermionic Hamiltonians with classical interactions. This QMA-hard problem is motivated by the Coulomb electron-elect…
Complexity of Fermionic 2-SAT
Maarten Stroeks, Barbara M. Terhal
We introduce the fermionic satisfiability problem, Fermionic -SAT: this is the problem of deciding whether there is a fermionic state in the null-space of a collection of fermio…
Quantum Phase Estimation without Controlled Unitaries
Laura Clinton, Toby S. Cubitt, Raul Garcia-Patron +3
In this work we demonstrate the use of adapted classical phase retrieval algorithms to perform control-free quantum phase estimation. We eliminate the costly controlled time evolut…
Solving Free Fermion Problems on a Quantum Computer
Maarten Stroeks, Daan Lenterman, Barbara Terhal +1
Simulating noninteracting fermion systems is a common task in computational many-body physics. In absence of translational symmetries, modeling free fermions on modes usually r…
Optimizing sparse fermionic Hamiltonians
Yaroslav Herasymenko, Maarten Stroeks, Jonas Helsen +1
We consider the problem of approximating the ground state energy of a fermionic Hamiltonian using a Gaussian state. In sharp contrast to the dense case, we prove that strictly -…
Spectral estimation for Hamiltonians: a comparison between classical imaginary-time evolution and quantum real-time evolution
Maarten Stroeks, Jonas Helsen, Barbara Terhal
We present a classical Monte Carlo (MC) scheme which efficiently estimates an imaginary-time, decaying signal for stoquastic (i.e. sign-problem-free) local Hamiltonians. The decay…
