Complexity Bounds for Hamiltonian Simulation in Unitary Representations
Naihuan Jing, Molena Nguyen
For any unitary representation on a finite-dimensional Hilbert space \(V\) with differential \(dρ: \mathfrak{g} \to \mathfrak{u}(V)\) for the Lie algebra , we cons…

Zassenhaus Expansion in Solving the Schrödinger Equation
Yali Du, Naihuan Jing, Molena Nguyen +1
A fundamental challenge in quantum simulation is approximating the time-evolution operator \(U(t)=e^{-i\mathcal{H}t}\) generated by a large sum of typically non-commuting Hamiltoni…
