摘要： Aspects of the present disclosure describe techniques for using a parabolic Cassegrain-type reflector for ablation. For example, a system for ablation loading of a trap is described that includes a reflector having a hole aligned with a loading aperture of the trap, and an atomic source positioned at a focal point of the reflector, where one or more laser beams are reflected from a reflective front side of the reflector and focused on a surface of the atomic source to produce an atomic plume, and the atomic plume once produced passing through the hole in the reflector and through a loading aperture of the trap for loading the trap. A method for ablation loading of a trap within a chamber in a trapped ion system is also described.

摘要： Aspects of the present disclosure relate generally to systems and methods for use in the implementation and/or operation of quantum information processing (QIP) systems, and more particularly, to a double individual-addressing multi-beam Raman system for use in QIP systems. A technique is described in which a first multi-channel modulator (MCM), a first telecentric zoom lens, and a first interleaver that form a first optical path of the Raman system that receives a first array of beams and adjusts the first array of beams to individually address atomic-based qubits in a chain from a first direction. Moreover, a second MCM, a second telecentric zoom lens, and a second interleaver form a second optical path of the Raman system that receives a second array of beams and adjusts the second arrays of beams to individually address the atomic-based qubits in the chain from a second direction different from the first direction.

摘要： Systems and methods for use in the implementation and/or operation of quantum information processing (QIP) systems or quantum computers, and more particularly, to benchmark-driven automation for tuning quantum computers are described. A method includes identifying a set of quantum gates and a number of experimental shots to perform a benchmark algorithm for active stabilization of one or more observables of the set of quantum gates and executing the benchmarking algorithm based on the set of quantum gates and the number of experimental shots. Moreover, in response to the benchmarking algorithm being successful, executing an algorithm on the quantum computer, and in response to the benchmarking algorithm being unsuccessful, iterating the benchmarking algorithm by adjusting the set of quantum gates until the benchmarking algorithm is successful or a preset number of iterations is reached.

A technique is described in which a first muti-channel modulator (MCM), a first telecentric zoom lens, and a first interleaver that form a first optical path of the Raman system that receives a first array of beams and adjusts the first array of beams to individually address atomic-based qubits in a chain from a first direction. Moreover, a second MCM, a second telecentric zoom lens, and a second interleaver form a second optical path of the Raman system that receives a second array of beams and adjusts the second arrays of beams to individually address the atomic-based qubits in the chain from a second direction different from the first direction.

摘要： Aspects of the present disclosure describe techniques for measuring collision rate with spatial filtering of scattered light. For example, a method for characterizing vacuum in a chamber is described that includes generating, inside the chamber, a potential well having a single, shallow potential region within which an ion is trapped, the shallow potential region having a lowest potential of the potential well, optically monitoring the ion within the potential well, detecting, based on the optically monitoring, a movement of the ion away from the shallow potential region in response to a collision with a background gas, and determining a pressure inside the chamber based on a rate of detected movements of the ion.

摘要： Aspects of the present disclosure describe techniques for mitigating charging on optical windows. For example, a device for mitigating charges inside a chamber of a trapped ion system is described that includes an array of parallel wires formed from a single, conductive plate by cutting elongated gaps through an entire thickness of the conductive plate that separate the wires, an outer portion of the conductive plate to which the wires are attached is configured to position the wires to run parallel to one or more trapped ions in the chamber and to position the wires between a dielectric component of the chamber and the one or more trapped ions. A chamber with such an array of parallel wires and a method of using such an array of parallel wires are also described.
