Abstract: A system is provided for imaging trapped ions in a quantum computer. The system includes an ion trap that traps qubit ions and includes electrodes that shuttle individual qubit ions between a first position and a second position spatially different from the first position. The system includes a first imaging lens that collects fluorescence from a qubit ion that is trapped over a surface of the ion trap; a first sensor in a first optical path output from the first imaging lens; a first pick-off mirror in a second optical path output from the first imaging lens that is different than the first optical path; a second imaging lens that collects fluorescence that is reflected from the first pick-off mirror; and a second sensor in a third optical path. Moreover, a controller controls the electrodes to shuttle the qubit ion from the first position to the second position.

Abstract: Aspects of the present disclosure may include a method and/or a system for spatially aligning microfabrication processes and laser writing processes on a wafer by preparing a pattern of alignment features across a wafer with known relative locations and orientations between elements of the pattern, aligning one or more laser writing processes to the alignment patterns, laser writing features into the wafer based on the prior process alignment, aligning one or more microfabrication processes to the microfabrication alignment patterns, and processing the wafer via the microfabrication steps using the results of the prior alignment step.

Abstract: Aspects of the present disclosure describe techniques for fast stabilization of multiple controller beams with continuous integrating filter. For example, a method is described for intensity stabilization of laser beams (e.g., ion controller beams) in a trapped ion system, where the method includes applying a linear array of laser beams to respective ions in a linear array of ions in a trap, performing, in response to the laser beams being applied, parallel measurements on the ions, the parallel measurements including multiple, separate measurements on each of the ions to identify fluctuations in intensity in the respective laser beams at each ion, and adjusting the intensity of one or more of the laser beams in response to fluctuations being identified from the parallel measurements. A corresponding system for intensity stabilization of laser beams in a trapped ion system is also described.

Abstract: A shaped central electrode is described that is placed between a pair of radio frequency (RF) rails of a trap configured to hold atomic-based qubits to control aspects of the operation of the trap. In one aspect, the shaping may involve forming a pinched region in the middle of the central electrode. The middle of the central electrode may correspond to the middle portion of the trap. The shaping of the central electrode may be achieved in different ways and may involve varying the width of the central electrode. The trap may be fabricated on a glass die or substrate, which itself may be shaped or not. The trap may be fabricated by various methods such as, but not limited to, patterned metal layers on glass or silicon substrates. A quantum information processing (QIP) system is also described that may include a trap having any of these features.

Abstract: Aspects of the present disclosure may include a method and/or a system for providing an acousto-optic deflector (AOD), emitting, toward a first deflector plate, a source beam, deflect the source beam, via the first deflector plate, to generate a deflected source beam toward the AOD, diffract, via the AOD, the deflected source beam to generate at least one diffracted beam, toward a second deflector plate, and deflect the at least one diffracted beam, via the second deflector plate, to generate a deflected diffraction light, wherein the source beam and the deflected diffraction light are collinear or substantially collinear.

Abstract: The disclosure describes various aspects of a software-defined quantum computer. For example, a software-defined quantum computing architecture for allocating qubits is described that includes an application programming interface (API); a quantum operating system (OS) on which the API executes, with the quantum OS including a resource manager and a switch; and a plurality of quantum cores connected by the switch of the quantum resource OS. Moreover, the resource manager of the quantum resource OS determines an allocation of a plurality of qubits in the plurality of quantum cores.
