摘要
Ultra-cold atom sensor for measuring a rotational velocity along a measurement axis comprises: means designed to generate a first and a second ultra-cold atom trap, one trap making it possible to immobilize a cloud of ultra-cold atoms in an internal state different from the other trap, at a predetermined distance from the measurement plane, the means comprising, at least one first and one second waveguide that are designed to propagate microwaves with angular frequencies ωa and ωb, the waveguides being non-secant and positioned symmetrically about an axis called the axis of symmetry, conductive wires integrated into the chip and designed to be flowed through by DC currents, the means being configured to modify the energy of the ultra-cold atoms in such a way as to create a potential minimum for the ultra-cold atoms in the internal state |a and a potential minimum for the ultra-cold atoms in the internal state |b, thus forming the first and second ultra-cold atom traps, and to move the traps along a closed path, traveled in one direction by the ultra-cold atoms of the first trap and in the opposite direction by the ultra-cold atoms of the second trap.
