Abstract: Systems and methods relate to selectively arranging a plurality of qubits into a spatial structure to encode a quantum computing problem. Exemplary arrangement techniques can be applied to encode various quantum computing problems. The plurality of qubits can be driven according to various driving techniques into a final state. The final state can be measured to identify an exact or approximate solution to the quantum computing problem.

Abstract: The present application discloses methods and apparatus for optically addressing qubits. An optical addressing system includes a source of electromagnetic radiation, at least one multi-frequency modulator configured to modulate electromagnetic radiation generated by the source of electromagnetic radiation to simultaneously produce at least two beams of electromagnetic radiation having different frequencies, each of which is configured to, when applied to multi-level quantum objects, at least partially drive one or more transitions between energy levels of the multi-level quantum objects, and a router configured to selectively direct the at least two beams of electromagnetic radiation to the multi-level quantum objects.

Abstract: Systems and methods relate to arranging atoms into 1D and/or 2D arrays; exciting the atoms into Rydberg states and evolving the array of atoms, for example, using laser manipulation techniques and high-fidelity laser systems described herein; and observing the resulting final state. In addition, refinements can be made, such as providing high fidelity and coherent control of the assembled array of atoms. Exemplary problems can be solved using the systems and methods for arrangement and control of atoms.

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.
