Abstract: Systems and techniques for active quantum memory (AQM) and quantum teleportation circuits with feedback are described. For instance, one or more aspects of the present disclosure may enable the indefinite storage of one or more qubits via a sequence of quantum teleportations involving the rapid periodic executions of a standard teleportation protocol with feedback (e.g., provided the total feedback cycle time is less than the decoherence time for a qubit). For each qubit stored, a pair of entangled qubits are injected on each feedback cycle and two qubits are measured. The stored quantum state may be passed repeatedly back-and-forth between two of the qubits, and the stored quantum state may be maintained by the input energy on each cycle required to initialize the entangled qubit pair (e.g., where the cycle period is chosen to be less than the decoherence time of the qubits to maintain state information over many cycles).

Abstract: A method and apparatus for evaluating the task-processing style of an individual by presenting that individual with a simulated situation and recording the individual's responses while resolving the situation. A subject undergoing the assessment is asked to assume the responsibilities of an Assistant Superintendent of Parks, replacing an individual who has unexpectedly left that position. The subject is first trained in the use of a touch-sensitive screen display for accessing data that may be useful in fulfilling the responsibilities of the simulated position and for providing input data used in the exercise. Each action by the subject undergoing the assessment is recorded in a raw data stream, along with the time that it occurred, and is statistically analyzed with respect to several parameters that define the subject's task-processing style.
