摘要： The disclosure describes various aspects of techniques for elliptical beam design using cylindrical optics that may be used in different applications, including in quantum information processing (QIP) systems. In an aspect, the disclosure describes an optical system having a first optical component having a first focal length, a second optical component having a second focal length and aligned with a first direction, and a third optical component having a third focal length and aligned with a second direction orthogonal to the first direction. The optical system is configured to receive one or more optical beams (e.g., circular or elliptical) and apply different magnifications in the first direction and the second direction to the one or more optical beams to image one or more elliptical Gaussian optical beams. A method for generating elliptical optical beams using a system as the one described above is also disclosed.

摘要： The disclosure describes various aspects of a practical implementation of multi-qubit gate architecture. A method is described that includes enabling ions in the ion trap having three energy levels, enabling a low-heating rate motional mode (e.g., zig-zag mode) at a ground state of motion with the ions in the ion trap; and performing a Cirac and Zoller (CZ) protocol using the low-heating rate motional mode as a motional state of the CZ protocol and one of the energy levels as an auxiliary state of the CZ protocol, where performing the CZ protocol includes implementing the multi-qubit gate. The method also includes performing one or more algorithms using the multi-qubit gate, including Grover's algorithm, Shor's factoring algorithm, quantum approximation optimization algorithm (QAOA), error correction algorithms, and quantum and Hamiltonian simulations. A corresponding system that supports the implementation of a multi-qubit gate architecture is also described.

摘要： The disclosure describes a method, an apparatus, a computer-readable medium, and/or means for reducing two-qubit gates in quantum circuits may include receiving a netlist including information relating to a first plurality of two-qubit quantum gates that form the quantum circuits, performing a controlled gate cancellation operation on the information relating to a first plurality of two-qubit quantum gates to produce a second plurality of two-qubit quantum gates that is functionally equivalent to the first plurality of two-qubit quantum gates, wherein a first number of two-qubit quantum gates in the first plurality of two-qubit quantum gates is larger than a second number of two-qubit quantum gates in the second plurality of two-qubit quantum gates, generating a new netlist containing information about the second plurality of two-qubit quantum gates, and providing the new netlist to implement a functionality of the quantum circuits based on the second plurality of two-qubit quantum gates.

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： A computer-implemented method, system and a computer readable medium storing executable instructions for optimizing a quantum circuit are disclosed. The computer-implemented method includes receiving one or more parameters for simulation of evolution of at least one quantum state of a chemical entity to be simulated; generating a quantum circuit for the simulation; performing one or more operations to minimize quantum resources to be used for the generated quantum circuit based on the one or more parameters; and placing quantum resources among one or more elementary logical units (ELUs) based on any one or more of: frequency of occurrence of the quantum resources in the generated quantum circuit, order of occurrence of the quantum resources in the generated quantum circuit, connectivity parameters between one or more quantum resources, efficiency of gates between specific quantum resources, quality of gates between specific quantum resources or a combination thereof.

摘要： Aspects of the present disclosure describe techniques for independently controlling an angle (e.g., change in tilt) and/or position (e.g., change in lateral position) of an optical beam. For example, an optical beam control system may include a telescope with rotatable mirrors and lenses configured to provide a path to an optical beam to produce an output optical beam, which in turn is made into parallel optical beams following a diffractive optical element. The optical beam control system may also include a detector system to a beam angle and/or a beam position of one of the parallel optical beams to generate feedback signal or signals to control a rotation of one or more of the mirrors in the telescope such as to adjust the beam angle, the beam position, or both of the parallel optical beams. The optical beam control system may be part of a quantum information processing (QIP) system.

摘要： An apparatus, method and system for resolving an n-number of photons from an optical source multiphoton event, the apparatus includes a cryostat includes a single-pixel superconducting nanowire single-photon detector (SNSPD) configured to receive an optical signal and therefrom produce a corresponding electrical signal, and a current bias source configured to supply a bias current to the SNSPD. The apparatus further includes a low-noise amplifier configured to produce a low-noise amplified electrical signal from the electrical signal, a signal processing circuit configured to receive the low-noise amplified electrical signal having a waveform rising edge of an n-number photon event to produce either a time-differentiated electrical signal by processing the waveform rising edge with a differentiating circuit to generate a differentiated peak corresponding to the n-number photon event, or a time-to-amplitude electrical signal by processing the waveform rising edge with a precision timing circuit to generate a rise time measurement corresponding to the n-number photon event. The apparatus further includes an amplitude discriminating device configured to determine an integer n-number photon event based on measuring a value of the n-number photon event.
