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…

Cayley's First Hyperdeterminant is an Entanglement Measure
Isaac Dobes, Naihuan Jing
Previously, it was shown that both the concurrence and -tangle on -qubit pure quantum states can be expressed in terms of Cayley's first hyperdeterminant \cite{dobes2024qubi…
