A cold atom generation apparatus comprising:

• a first cooling means that cools and traps, with a first light and a magnetic field, atoms in a first state in a first region;
• a means that the atoms trapped in the first region are relaxed to a second state by an optical pump caused during a laser cooling process;
• a means that moves the atoms to a second region where a magnetic field is non-zero due to equilibrium between a magnetic force acting on the atoms in the second state, a force of gravity, and a radiation pressure of a second light illuminated onto the atoms in the second state;
• a second cooling means that irradiates, in the second region, the second light to the atoms in the second state, to thereby cool the atoms in the second state;
• a means that optically pumps the atoms to a third state, insensitive to a magnetic field, in the second region;
• and
• a means that transports the atoms in the third state from the second region to a post device by a moving optical lattice or an optical dipole guide, wherein
• the atoms in the first state which are input to the first region are cooled by the first cooling means and are transitioned to the second state,
• the atoms in the second state are moved from the first region to the second region by the equilibrium between the magnetic force, the force of gravity, and the radiation pressure from the second light,
• a state of the atoms moved to the second region is changed to the third state through an optical pumping manipulation after cooling by the second cooling means, and
• the atoms in the third state are trapped in the moving optical lattice of the optical dipole guide, and are transported from the second region to the post device.

A method of generating cold atoms, the method comprising:

• a first cooling step of cooling and trapping, with a first light and a magnetic field, atoms in a first state in a first region;
• a magnetic trap step of trapping, with a magnetic force, atoms optically pumped to a second state;
• a step of moving the atoms from the first region to a second region;
• a second cooling step of irradiating with a second light onto the atoms in the second state moved from the first region to the second region, to thereby cool the atoms in the second state;
• and
• a supply step of optically pumping the atoms to a third state, insensitive to a magnetic field, in the second region, and transporting the atoms to a post device by a moving optical lattice or an optical dipole guide.
