Abstract: The disclosure describes various aspects of a software-defined quantum computer. For example, a software-defined quantum computing architecture for allocating qubits is described that includes an application programming interface (API); a quantum operating system (OS) on which the API executes, with the quantum OS including a resource manager and a switch; and a plurality of quantum cores connected by the switch of the quantum resource OS. Moreover, the resource manager of the quantum resource OS determines an allocation of a plurality of qubits in the plurality of quantum cores.

Abstract: The disclosure describes various aspects of a software-defined quantum computer. For example, a method is described for generating an intermediate representation of source code for a software-defined quantum computer. The method includes performing a lexical analysis on a high-level intermediate representation of a quantum programming language; performing semantic analysis on an output of the lexical analysis; and generating a mid-level intermediate representation of the quantum programming language based on an output of the semantic analysis.

Abstract: Methods and apparatus for long-distance quantum communication and scalable quantum computation are disclosed. The methods and apparatus are based on probabilistic ion-photon mapping. Scalable quantum computation is achieved by forming deterministic quantum gates between remotely located trapped ions by detecting spontaneously emitted photons, accompanied by local Coulomb interaction between neighboring ions. Long-distance quantum communication and scalable quantum communication networks formed by employing a number of remote nodes that each include an ion trap and by employing probabilistic photon-mediated entanglement between the ions in each ion trap.

Abstract: An orthopedic nail for intramedullary fixation of fractures in long bones has an axially outwardly opening mouth in a first end thereof including a pair of side edge portions and an inward bight portion. A method of fixation of a fracture of a long bone includes driving a distal fastener transverse the bone on a medial frontal plane and axially inserting the mouth end of the nail into the medullary canal with the mouth on the same plane as the distal fastener. The fastener should be received within the mouth and seated against the bight portion due to the axial movement of the nail. A special jig is provided for accurately locating a second distal fastener if one is indicated. A retractable insertion device covers the mouth during nail insertion to reduce the likelihood of snagging vessels.
