摘要： Ultracold atoms sensor allowing rotational velocity to be measured about a measurement axis (14), said sensor comprising: means suitable for generating first and second ultracold atom traps (T1, T2), one trap allowing a cloud of ultracold atoms (12) to be immobilised in an internal state different from the other trap, at a preset distance from said measurement plane, said means comprising ◊ at least first and second waveguides (CPW1, CPW2) that are suitable for propagating microwaves with angular frequencies ωa and ωb, said waveguides being non-secant and placed symmetrically with respect to an axis called the axis of symmetry (Sy), ◊ and conductive wires integrated into said chip (1) and suitable for passing DC currents; said means being configured to modify the energy of said ultracold atoms so as to create a potential minima for the ultracold atoms in the internal state |a> and a potential minima for the ultracold atoms in the internal state |b>, thus forming said first and second ultracold atom traps, and to move said traps (T1, T2) along a closed path (16), said path being traced in one direction by the ultracold atoms of the first trap and in the opposite direction by the ultracold atoms of the second trap.

摘要： Waveguide includes fork with first and second bifurcated ends coupled to loop section and separated by angle determined based on velocities of portions of quantum mechanical wavefunction of atoms traveling above waveguide. Waveguide propagates blue-detuned laser having first evanescent field that repels atoms away from waveguideand red-detuned laser having second evanescent field that attracts atoms toward waveguide, together creating potential minimum/well. Laser cooling atoms, causing atoms positioned in potential minimum/well to move toward first fork section following potential minimum/well. Atomic state initialization section initializes atomic states of atoms to known ground-state configuration. Beam splitter section splits quantum mechanical waveform of each atom above surface of diverging waveguide into first portion at first velocity that travels into first end of first fork section into first loop section and second portion at second velocity that travels into second end of first fork section into first loop section.
