Beyond Trotterization: Variational Product Formulas for Quantum Simulation
Ibsal Assi, Michael Vogl, Meenu Kumari +1
We propose a variational alternative to the Trotter-Suzuki decomposition that provides greater control over errors while preserving the unitary structure of time evolution. The var…

NonHermitian Topological Phases in a Hermitian Modified Bosonic Kitaev Chain
Raditya Weda Bomantara, Ibsal Assi, J. P. F. LeBlanc +1
We present a modification to the bosonic Kitaev chain that, despite being Hermitian, supports both nonHermitian skin effect and nontrivial topological edge modes in its excitation…
