Abstract: An optical cavity array includes a plurality of mirrors that form an optical cavity, a first lens system located within the optical cavity, and a second lens system located within the optical cavity. The first lens system has a first output facing a first mirror of the plurality of mirrors and a second output facing a second mirror of the plurality of mirrors. The second lens system has a second input facing the first input and a second output facing the second mirror. The first and second lens systems are configured such that the optical cavity supports longitudinal modes that are transversely non-degenerate, forming spatially separated waists that lie along a focal plane that is axially located between the first and second inputs. When the longitudinal modes are excited, the waists may be used as an array of optical dipole traps.

Abstract: Technologies for resource-efficient quantum error correction are disclosed. A quantum computer may include physical gate qubits, capable of general quantum gate operations such as single-qubit operations and nearest-neighbor two-qubit operations. Each physical qubit gate may be controllably coupled to a quantum memory. The quantum memory may have a lower per-gate error rate than the physical qubit gates as well as a lower per-qubit cost. Because errors accrue at a lower rate in the quantum memory, the physical gate qubits may be able to perform error correction for a large number of logical qubits in the quantum memory, even if the physical gate qubits have an error rate relatively close to an error threshold.

Abstract: Technologies for tuning a resistance of tunnel junctions such as Josephson junctions are disclosed. In the illustrative embodiment, a Josephson junction is heated to 85 Celsius, and an electric field is applied to the Josephson junction. The heat and the electric field cause the resistance of the Josephson junction to increase. Monitoring the Josephson junction during the application of the electric field allows for the resistance of the Josephson junction to be adjusted to a particular value.

Abstract: A millimeter-wave resonator is produced by drilling a plurality of holes into a piece of metal. Each hole forms an evanescent tube having a lowest cutoff frequency. The holes spatially intersect to form a seamless three-dimensional cavity whose fundamental cavity mode has a resonant frequency that is less than the cutoff frequencies of all the evanescent tubes. Below cutoff, the fundamental cavity mode does not couple to the waveguide modes, and therefore has a high internal Q. Millimeter waves can be coupled into any of the tubes to excite an evanescent mode that couples to the fundamental cavity mode. The tubes also provide spatial and optical access for transporting atoms into the cavity, where they can be trapped while spatially overlapping the fundamental cavity mode. The piece of metal may be superconducting, allowing the resonator to be used in a cryogenic environment for quantum computing and information processing.

Abstract: Technologies for a long-lived 3D multimode microwave cavity are disclosed. In the illustrative embodiment, a series of overlapping holes are drilled into a monolithic block of aluminum forming a cavity. The dimensions of the cavity formed by the overlapping holes can be made long by drilling a long series of holes in a row and can be made high by drilling holes a certain depth into the cavity. If two dimensions of the cavity are bigger than the diameter of the holes used to create the cavity, then the cavity can support electromagnetic waves that cannot propagate through the holes, leading to a long lifetime in the cavity. A superconducting qubit or other non-linear element can be inserted into the cavity, which can controllably interact with each of several modes of the cavity. In this way, the modes of the cavity can act as components in a quantum memory.

Abstract: An exemplary method for achieving an error divisible gate in a quantum system includes selecting an intrinsic gate error rate threshold for a gate coupled between a pair of qubits, and determining a first gate time to execute a full entangling gate rotation with a first error rate less than the intrinsic gate error rate threshold. The exemplary method further includes, based on the time to execute the full entangling gate, applying, to the gate, a second gate rotation having a second gate time less than the first gate time to determine a second error rate. The exemplary method further includes selecting the second gate time as a final gate time when the second error rate is smaller than the first error rate.
