Quantum simulation of time-dependent Hamiltonians via commutator-free quasi-Magnus operators
Pablo Antonio Moreno Casares, Modjtaba Shokrian Zini, Juan Miguel Arrazola
Hamiltonian simulation is arguably the most fundamental application of quantum computers. The Magnus operator is a popular method for time-dependent Hamiltonian simulation in compu…
