An electronic state splitter for atoms comprises an atom supplier, an atom movement path, a probe laser source, and a magnetic field generator. The atom supplier supplies atoms moving at a constant velocity along the atom movement path. The probe laser source supplies a probe laser propagating in the atom movement path in the same direction as or opposite to the motion of the atoms on the same axis as the atom movement path. The magnetic field generator generates a magnetic field orthogonal to the atom movement path in the atom movement path to mix the wave function of the clock upper state with the electronic state allowing electric dipole transitions, allowing pulsed excitation of clock transitions by the probe laser uniform in time and space. Accordingly, continuous spectroscopy of atomic transitions and frequency control of the probe laser are possible, which improves the stability of the atomic clock.

The atomic electronic state separator (1) of the present invention includes: an atomic supply unit (11), an atomic movement path (12), a probe laser source (13), and a magnetic field generating unit (M). The atomic supply unit (11) supplies atoms that move in the atomic movement path (12) at a certain speed. The probe laser source (13) supplies a probe laser that propagates coaxially with the atomic movement path (12) in a direction opposite to or the same as the direction of atomic movement. The magnetic field generating unit (M) generates a magnetic field orthogonal to the atomic movement path (12) in the atomic movement path (12) and mixes it with the wave function of the electronic state that allows electric dipole transitions, thereby enabling pulse excitation of clock transitions based on the same probe laser in time and space. Alternatively, a magnetic shielding member can pulse excite clock transitions by shielding the magnetic field applied in the atomic movement path (12) and spatially changing the Zeeman frequency shift, thereby enabling pulse excitation of clock transitions by the same probe laser in time and space. As a result, it is possible to continuously perform spectral analysis of atomic transitions and frequency control of the detection laser, thereby improving the stability of the atomic clock.

Quantum mechanical systems, such as for instance electronic states in molecules or solid bodies, can be simulated using quantum computers. However, at present quantum computers only provide a limited quantity of qubits for the calculation. This deficiency is attributable to unsolved problems in connection with inherent noise and scalability, with the result that quantum computers currently only enable simulations of small quantum systems. A method simulates and evaluates an electronic system with a continuous spectral density on the basis of the interruption of the quantum simulation by measurements. The quantum simulation is interrupted to read the qubits, the qubit measurements are stored in a classical parity register and restored to the qubits, and the simulation is continued after the restore.
