Abstract:
A method is presented, which includes trapping a charged particle at a first position using an electromagnetic trap and providing a static magnetic field at the first position such that a qubit transition of the charged particle is defined, and providing, using an entangling electrode, an oscillating magnetic field. The oscillating magnetic field present at the first position does not contain a polarisation component which directly couples to the qubit transition. The oscillating magnetic field has a spatial gradient at the first position, of the polarisation component of the oscillating magnetic field which couples the qubit transition to the motion of the charged particle.
Abstract:
A detector system comprises a first analytical stage configured to isolate ions from a sample, a field induced fragmentation stage configured to fragment the ions, a second analytical stage configured to characterize the ions, and at least one detector. The first analytical stage and the second analytical stage each comprise a differential mobility spectrometer. The field induced fragmentation stage comprises strips configured to create an electric field therebetween. In certain embodiments, the system further comprises a port configured between the first analytical stage and the field induced fragmentation stage, configured to introduce a reagent.
