Techniques for the fabrication of electrodes and the shaping of glass dies or substrates are described to produce metal-on-glass ion traps. These ion traps may be configured to have open light access and high aspect trenches for the electrodes. For example, the glass substrate may be shaped to provide high numerical aperture (NA) light access by having angled cutouts, electrode structures with high aspect trenches, angled wire bonds for electrical connections, the angled wire bonds providing additional clear access by one or more laser beams, or a combination of any of these features. A quantum information processing (QIP) system is also described that may include an ion trap having any of these features.

A method of creating an optical atom trap comprises the steps of providing an incoherent light field with a light source apparatus, by creating a pulsed laser light beam of laser pulses with a repetition rate equal to or above 100 kHz and a relative spectral width of 10.sup.−4 to 10.sup.−2, coupling the pulsed laser light beam to an input end of a multimode waveguide device and guiding the pulsed laser light beam by total internal reflection to an output end of the multimode waveguide device, wherein the incoherent light field is provided at the output end, and creating the optical atom trap for trapping atoms in an atom trap chamber device by coupling the incoherent light field to the atom trap chamber device, wherein the optical atom trap has a trap frequency and the atoms have multiple resonance frequencies, and the laser pulses for providing the incoherent light field are created such that the repetition rate is above the trap frequency and the spectral width is below a spectral range between the resonance frequencies. Furthermore, an optical atom trap apparatus for optically trapping atoms is described.

The polarization-dependent characteristics of a tightly focused optical trap are utilized to realize triaxial electric field force calibration of particles through a one-dimensional electric field quantity calibration device. The method of the present application enables a particle electric field force calibration system to be compatible with particle delivery and particle detection systems; the device is simplified and calibration complexity is reduced.

An ion trap apparatus is provided. The ion trap apparatus comprises two or more radio frequency (RF) rails formed with substantially parallel longitudinal axes and with substantially coplanar upper surfaces; and two or more sequences of trapping and/or transport (TT) electrodes with each sequence formed to extend substantially parallel to the substantially parallel longitudinal axes of the RF rails. The two or more RF rails and the two or more sequences of TT electrodes define an ion trap. The two or more sequences of TT electrodes are arranged into a number of zones. Each zone comprises wide matched groups of TT electrodes and at least one narrow matched group of TT electrodes. A wide TT electrode is longer and/or wider in a direction substantially parallel to the substantially parallel longitudinal axes of the RF rails than a narrow TT electrode.

A quantum-mechanics station (Ψ-station) and a cloud-based server cooperate to provide quantum mechanics as a service (ΨaaS) including real-time, exclusive, interactive sessions. The Ψ-station serves as a system for implementing “recipes” for producing, manipulating, and/or using quantum-state carriers, e.g., rubidium 87 atoms. The cloud-based server acts as an interface between the station (or stations) and authorized users of account holders. To this end, the server hosts an account manager and a session manager. The account manager manages accounts and associated account-based and user-specific permissions that define what actions any given authorized user for an account may perform with respect to a Ψ-station. The session manager controls (e.g., in real-time) interactions between a user and a Ψ-station, some interactions allowing a user to select a recipe based on wavefunction characterizations returned earlier in the same session.
