Optimal scheduling in probabilistic imaginary-time evolution on a quantum computer

Optimal scheduling in probabilistic imaginary-time evolution on a quantum computer

Ground-state preparation is an important task in quantum computation. The probabilistic imaginary-time evolution (PITE) method is a promising candidate for preparing the ground state of the Hamiltonian, which comprises a single ancilla qubit and forward- and backward-controlled real-time evolution o...
