Abstract: In a general aspect, a gate is formed for a quantum processor. In some implementations, an arbitrary program is received. The arbitrary program includes a first sequence of quantum logic gates, which includes a parametric XY gate. A native gate set is identified, which includes a set of quantum logic gates associated with a quantum processing unit. A second sequence of quantum logic gates corresponding to the parametric XY gate is identified, which includes a parametric quantum logic gate. Each of the quantum logic gates in the second sequence is selected from the native gate set. A native program is generated. The native program includes a third sequence of quantum logic gates. The third sequence of quantum logic gates corresponds to the first sequence of quantum logic gates and includes the second sequence of quantum logic gates. The native program is provided for execution by the quantum processing unit.

Abstract: Systems and methods for cleansing blood are disclosed herein. The methods include acoustically separating target particles from elements of whole blood. The whole blood and capture particles are flowed through a microfluidic separation channel formed in a thermoplastic. At least one bulk acoustic transducer is attached to the microfluidic separation channel. A standing acoustic wave, imparted on the channel and its contents by the bulk acoustic transducer, drives the formed elements of the blood and target particles to specific aggregation axes.

Abstract: A prosthetic valve assembly includes an annular frame having an inner radial surface, an outer radial surface, and defining an inner lumen. The prosthetic valve assembly further includes a leaflet assembly including at least one leaflet having an inner radial surface and an outer radial surface. The at least one leaflet is disposed at least partially within the inner lumen of the annular frame. The prosthetic valve assembly includes a crimping accessory device having a handle and at least one shielding member removably disposed between the outer radial surface of the at least one leaflet and the inner radial surface of the annular frame. The at least one shielding member is configured to reduce physical contact between the at least one leaflet and the inner radial surface of the annular frame.

Abstract: Embodiments of an apparatus, and a method for crimping expandable stents or prosthetic valves having a radially expandable and compressible annular body and one or more protruding anchors extending from the body using the apparatus, where the apparatus comprise a housing, a plurality of circumferentially arranged nesting jaws, and an actuator configured to move the jaws radially inwardly to reduce the size of the crimping aperture, thereby radially compressing the annular body of the prosthetic valve or stent. In particular embodiments, a selected set of the jaws, each having a front side and a recessed portion in its front side adjacent to its inner end. The recessed portions of the selected jaws collectively are sized and shaped to receive the one or more anchors of the prosthetic valve when the annular body is positioned within the crimping aperture.
