Abstract: Example methods and mechanisms are described herein for implementing and adiabatically operating a topological quantum computing (TQC) phase gate that complements the existing Clifford operations, and thereby allows universal quantum computation with Majorana systems. Further embodiments include a testing system for the phase gate that is feasible with Majorana zero modes and demonstrates violations of the CHSH-Bell inequality. Further, the design used for the testing of the inequality leads directly to a practical platform for performing universal TQC with Majorana wires in which explicit braiding need never occur.

Abstract: An apparatus includes an electrostatic discharge (ESD) protection device configured to protect a circuit from ESD conditions. The protection device includes an emitter region having a first diffusion polarity; a collector region laterally spaced apart from the emitter region, and having the first diffusion polarity; and a barrier region interposed laterally between the emitter region and the collector region while contacting the emitter region. The barrier region has a second diffusion polarity opposite from the first diffusion polarity. The device can further include a base region having the second diffusion polarity, and laterally surrounding and underlying the emitter region and the barrier region. The barrier region can have a higher dopant concentration than the base region, and block a lateral current flow between the collector and emitter regions, thus forming a vertical ESD device having enhanced ESD performance.

Abstract: A “dry” packaging in which a prosthetic heart valve is packaged within a container with hydrogel that can be provided in many forms. Certain embodiments include hydrogel that is preloaded with glycerol or the like. The hydrogel regulates the humidity within the container through a diffusion-driven mechanism if a gradient of humidity between the inside and the outside of the hydrogel exists. Humidity regulation is important to prevent the tissue of the valve structure from drying out. When the partially-hydrated hydrogel is present within container, which is saturated with air of a predefined humidity, the water molecules from the air will be absorbed by the hydrogel if the air humidity is high (i.e. when the thermodynamics favor hydrogel hydration) or vice versa. Various embodiments are configured to also house at least a portion of a delivery device for delivering the prosthetic heart valve.

Abstract: Aspects of the disclosure relate to “wet” transcatheter prosthetic heart valve or other implant packaging and assemblies in which a prosthetic heart valve or other implant is loaded into a first portion of a delivery device and positioned within a container in which sterilizing fluid is retained to sterilize interior portions of the container as well as provide moisture to prevent the implant from drying out. The disclosure also relates to methods of sterilizing the disclosed assemblies. Some disclosed methods include at least two sterilizing steps and adjustment of a mechanical seal member or formation of multiple seals so that areas proximate the seals are also sterilized during the sterilization process.
