Abstract
The present invention aims at enabling a gate-type quantum computer to deal with actual problems. There is provided a quantum computer including: a quantum register holding qubits, a control gate performing an operation on the quantum register, and a readout unit observing a state of the quantum register; and the quantum computer repeating longitudinal relaxation to the ground state by gradually changing Hamiltonian H(t) for a predetermined time, wherein the unitary operation determined by the Hamiltonian H(t) at each time is performed with the control gate for a time of about a longitudinal relaxation time, the quantum state is relaxed every time of about the longitudinal relaxation time, and the ground state prepared for an initial state is time-evolved to the ground state of the Hamiltonian which is defined as a problem.
