Linear combination of Hamiltonian simulation for non-unitary dynamics with optimal state preparation cost
内容： We propose a simple method for simulating a general class of non-unitary dynamics as a linear combination of Hamiltonian simulation (LCHS) problems. LCHS does not rely on converting the problem...
