Generalizations of quantum amplitude amplification and amplitude estimation algorithms work with non-boolean oracles (by way of definition, the action of a non-boolean oracle U φ on an eigenstate |x is to apply a state-dependent phase-shift φ(x); unlike boolean oracles, the eigenvalues exp(iφ(x)) of a non-boolean oracle are not restricted to be ±1). The non-boolean amplitude amplification algorithm preferentially amplifies the amplitudes of the eigenstates based on the value of φ(x). Starting from a given initial superposition state |ψ 0 , the basis states with lower values of cos(φ) are amplified at the expense of the basis states with higher values of cos(φ). The non-boolean quantum mean estimation algorithm uses quantum phase estimation to estimate the expectation ψ 0 |U φ |ψ 0 (i.e., the expected value of exp(iφ(x)) for a random x sampled by making a measurement on |ψ 0 ). The quantum mean estimation algorithm offers a quadratic speedup over its counterpart boolean algorithm known in the art.

A quench protection system, and associated methods of manufacturing and operating the same, including a bifilar coil defined by first and second insulated conductors co-wound to form a persistent current loop. A first coil splice electrically connects the first insulated conductor start-to-end to the second insulated conductor; and a second coil splice electrically connects the second insulated conductor start-to-end to the first insulated conductor. First and second current leads electrically connect to the first and second coil splices, respectively. An input current received by the first current lead (e.g., from a power supply or a capacitor) is split by the first coil splice into a first portion passed clockwise through the first insulated conductor and into a second portion passed counterclockwise through the second insulated conductor, to define a parallel differential mode. The bifilar coil in the parallel differential mode may be characterized by an inductance L of approximately 0.

Beam delivery and/or beam aiming subsystems included in a fast neutron therapy system. The beam delivery subsystem comprises a beamline having linear and curved portions. Quadrupoles along the beamline focus particles conveyed between an axled input and a neutron source (e.g., beryllium). A bend magnet(s) directs the particles to collide with the neutron source to release neutrons. A gantry (e.g., concrete, steel) includes an annular rim and opposing annular flanges that form a radial cavity and a perimeter “shield zone” channel. A collimator assembly (e.g., steel) projects radially inward from a slot void in the annular rim. A secondary collimator (e.g., steel, hydrogenous material) presents a barrel extending radially toward the gantry isocenter. The two collimators contour the neutrons into a high linear energy transfer (LET) beam. A drive rotates the gantry to set the delivery angle over approximately 360 degrees about the isocenter (e.g., patient table).

A method comprising: 1) positioning an inflatable pipe plug inside a high-vacuum beam line assembly proximate an axial gap between two beam tubes mechanically connected by a bellows-encased radio frequency (RF) shield; 2) inflating a balloon of the pipe plug proximate the axial gap to exert a uniform pressure along dislocated fingers of the RF shield; 3) angularly bending the bellows to enlarge a repair portion of the axial gap to a width larger than the dislocated finger(s); and 4) returning the dislocated finger(s) to the operation-ready RF shield position under the uniform pressure before 5) deflating and removing the inflatable pipe plug. A corrector system kit may comprise a set of custom-sized balloon(s) of a nitrile material type, a fixed-length or tailorable delivery hose, and a connector(s). A fluid (e.g., gas, liquid) pump delivers pressured fluid to the selected/tailored connector, through the delivery hose, and into the balloon.

A digital-to-analog converter circuit that creates an analog waveform from an input digital waveform. Operating the circuit comprises using the input digital waveform to 1) operate a charge control switch to set a charge time period, 2) operate a discharge control switch to set a discharge time period, 3) set a charge current magnitude using a charge gain, and 4) set a discharge current magnitude using a discharge gain. A charge source electrically charges a load capacitor during the charge time period (i.e., the charge mode). A discharge source electrically discharges the load capacitor during the discharge time period (i.e., the discharge mode). A circuit output transmits the analog waveform defined by the charge mode and the discharge mode. A charge current magnitude greater than the discharge current magnitude produces an upward-sloping analog waveform. A charge current magnitude less than the discharge current magnitude produces a downward-sloping analog waveform.
