<p>A temporally continuous matter wave beam splitter comprises a plurality of intersecting and interfering laser beams kL which act as waveguides for a matter wave beam. The laser beams of the waveguides each have a frequency detuned below a frequency of an internal atomic transition of the matter wave and the matter wave has a wavevector which is an integral multiple of the wavevector of the laser beams within a region of intersection of the laser beams. The continuous matter wave beam splitter may be formed on the surface of a solid-state device, preferably as part of an atom interferometer. A cold atom gyroscope, a cold atom accelerometer or a cold atom gravimeter comprising such a solid state device are also disclosed, as is a quantum computer comprising such a solid state device, wherein atoms of the matter wave beam are in an entangled quantum state.</p> |
