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…
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…
Classifying fermionic states via many-body correlation measures
Mykola Semenyakin, Yevheniia Cheipesh, Yaroslav Herasymenko
Understanding the structure of quantum correlations in a many-body system is key to its computational treatment. For fermionic systems, correlations can be defined as deviations fr…
Efficient learning of quantum states prepared with few fermionic non-Gaussian gates
Antonio Anna Mele, Yaroslav Herasymenko
The experimental realization of increasingly complex quantum states underscores the pressing need for new methods of state learning and verification. In one such framework, quantum…
