  • Publication number: 20240346352
    Abstract: Dynamically reconfigurable architectures for quantum information and simulation are provided. A plurality of neutral atoms is provided. Each neutral atom is disposed in a corresponding optical trap. Each of the plurality of neutral atoms is prepared in a mF=0 clock state. A pair of neutral atoms of the plurality of neutral atoms is entangled by directing a laser pulse thereto. The laser pulse is configured to transition the pair of neutral atoms through a Rydberg state. The optical trap corresponding to at least one neutral atom of the pair is adiabatically moved, thereby moving one atom of the pair relative to the other atom of the pair without destroying entanglement of the pair.

  • Patent number: 12014246
    Abstract: Systems and methods are disclosed for making a quantum network node. A plurality of scoring function F values are calculated for an array of at least two photonic crystal cavity unit cells, each having a lattice constant a and a hole having a length Hx and a width Hy. A value of a, a value of Hx, and a value of Hy are selected for which a scoring function value is at a maximum. A waveguide region and the array of at least two photonic crystal cavity unit cells based on the selected values are formed on a substrate. At least one ion between a first photonic crystal cavity unit cell and a second photonic crystal cavity unit cell are implanted and annealed into a quantum defect. A coplanar microwave waveguide is formed on the substrate in proximity to the array of at least two photonic crystal cavity unit cells.

  • Publication number: 20240185113
    Abstract: Error detection and correction in a quantum computer are provided. The quantum computer includes qubits encoding a plurality of data qudits and an ancilla qudit. The qubits encoding the plurality of data qudits are arranged into a grouping wherein the qubits encoding each of the data qudits are within an interaction distance of an interacting state of the qubits encoding the ancilla qudit. A leakage error of a first data qudit of the plurality of data qudits into the interacting state is detected by detecting a state of the ancilla qudit. Quantum states of the qudits are selected such that angular momentum selection rules prohibit mixing between the selected quantum states during a leakage error of one of the qudits into a noninteracting state. The leakage error is corrected by optical pumping of the noninteracting state, preserving coherence of the selected quantum states in the absence of the leakage error.

  • Patent number: 11985451
    Abstract: A method of generating uniform large-scale optical focus arrays (LOT As) with a phase spatial light modulator (SLM) includes identifying and removing undesired phase rotation in the iterative Fourier transform algorithm (IFTA), thereby producing computer-generated holograms of highly uniform LOT As using a reduced number of iterations as compared to a weighted Gerchberg-Saxton algorithm. The method also enables a faster compensation of optical system-induced LOT A intensity inhomogeneity than the conventional IFTA.
