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…
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…
Homological Quantum Rotor Codes: Logical Qubits from Torsion
Christophe Vuillot, Alessandro Ciani, Barbara M. Terhal
We formally define homological quantum rotor codes which use multiple quantum rotors to encode logical information. These codes generalize homological or CSS quantum codes for qubi…
