Quantum state driving: measurements versus pulses
Yi-Hsiang Chen
The quantum Zeno effect is well-known for fixing a system to an eigenstate by frequent measurements. It is also known that applying frequent unitary pulses induces a Zeno subspace…

Quantum algorithm for time-dependent Hamiltonian simulation by permutation expansion
Yi-Hsiang Chen, Amir Kalev, Itay Hen
We present a quantum algorithm for the dynamical simulation of time-dependent Hamiltonians. Our method involves expanding the interaction-picture Hamiltonian as a sum of generalize…
