  • Publication number: 20240256936
    Abstract: A quantum computing four-tone phase insensitive Mølmer-Sørensen gate system comprises a confinement apparatus, manipulation source(s), and beam path system(s). The confinement apparatus is configured to confine quantum objects. A qubit space of the quantum objects is defined comprising two qubit states. The manipulation source(s) is configured to generate first, second, third, and fourth manipulation signals. The first and fourth manipulation signals are configured to interact to provide a red sideband signal corresponding to a Raman transition between the two qubit states. The second and third manipulation signals are configured to interact to provide a blue sideband signal corresponding to the Raman transition. The beam path system(s) defines first and second beam paths. The first (second) beam path is configured to provide the first and second (third and fourth) manipulation signals to the defined location. A non-zero angle exists between the first and second beam paths at the defined location.

  • Publication number: 20240183583
    Abstract: A method for cooling an atomic object is provided. The method includes controlling voltage sources to cause a confinement apparatus to confine the atomic object at a position defined by the confinement apparatus, where motion of the atomic object at the position defined by the confinement apparatus comprises contributions from one or more radial motional modes of the atomic object and contributions from one or more axial motional modes of the atomic object; and causing at least one first control signal to be provided to at least one control electrode of the plurality of control electrodes, where an oscillating potential is generated at the position defined by the confinement apparatus and configured to cause at least one radial mode of the one or more radial modes of the atomic object to couple to at least one axial mode of the one or more axial modes of the atomic object.

  • Publication number: 20230409941
    Abstract: Embodiments of the present disclosure provide for qubit reuse within a quantum computing environment for a quantum program in a quantum computing environment. In this regard, embodiments generate an optimized quantum program based on an initial quantum program. In some embodiments, the optimized quantum program may utilize fewer computing resources, such as qubits, than the initial quantum program. In some embodiments, the optimized quantum program may be compiled and executed in the quantum computing environment.

  • Publication number: 20230125251
    Abstract: A controller of a QCCD-based quantum computer is configured to perform arbitrary angle two-qubit gates using global single-qubit gates and rotations of arbitrary angles and/or individual single-qubit gates that include two-qubit gate primitives, such as a phase-independent anti-symmetric two-qubit gate, and that are not individually addressed.

  • Publication number: 20230049490
    Abstract: An atomic object confined in a particular region of an atomic object confinement apparatus is cooled using an S-to-P-to-D EIT cooling operation. A controller associated with the atomic object confinement apparatus controls first and second manipulation sources to respectively provide first and second manipulation signals to the particular region. The first manipulation signal is characterized by a first wavelength corresponding to a transition between an S manifold and a P manifold of a first component of the atomic object and detuned from the S-to-P transition by a first detuning. The second manipulation signal is characterized by a second wavelength corresponding to a transition between the P manifold and a D manifold of the first component and detuned from the P-to-D transition by a second detuning. The first and second detunings selected to establish a dark state associated with a two-photon transition between the S manifold and the D manifold.

  • Publication number: 20220382709
    Abstract: A quantum computer controller receives a quantum circuit comprising circuit slices. The first slice comprises a past causal cone of a first system qubit wire at a fully evolved level of the circuit. An i-th slice contains all gates that are within a past causal cone of a system qubit wire that reaches the fully evolved level in slice i that are not in the past causal cone of a system qubit wire that reaches the fully evolved level in slice i?j. The controller causes execution of the i-th slice using the physical qubits; causes a physical qubit that was evolved along a system qubit wire to the fully evolved level via execution of the i-th slice to be reinitialized and reintroduced onto a system qubit wire at a base level of the i+m-th slice; and causes the quantum computer to use the physical qubit to execute the i+m-th slice.

  • Patent number: 10733524
    Abstract: A quantum computing D-state AC-Stark shift gate system comprises at least one gate manipulation source and one or more ions trapped in an ion trap. The at least one gate manipulation source is configured to generate a first gate manipulation signal and a second gate manipulation signal. The first and second gate manipulation signals couple an ion between a set of S-states and a set of D-states. The first and second gate manipulation signals apply a force to an ion of the one or more ions that is dependent on the internal state of the ion. The first and second gate manipulation signals are configured to couple internal states of the ions to their motional state without appreciably altering a population of the ions within the set of S-states.
