Abstract: A measurement based photonic quantum computing system includes an optical input generator configured for receiving first optical paired inputs, and second optical paired inputs, inducing a first predefined relative time delay into each optical paired inputs for making one mode of the first and one mode of the second optical paired inputs into coexisting optical inputs, representing a logic level of the quantum computing system, a delocalized measurement architecture configured for optically interfering coexisting optical inputs for generating intermediate outputs, optically interfering by first and second variable path-couplers for each intermediate output a first mode of the intermediate outputs to a second mode of first or second neighboring intermediate outputs, respectively, for generating interfered outputs, and detecting by two optical detectors, preferably homodyne optical detectors, each mode of the intermediate outputs and interfered outputs, such that the delocalized measurement architecture is conf

Abstract: An apparatus includes a processing pipeline with a stationary structure motion corrector, a stationary structure remover and a flowing structure detector. The stationary structure motion corrector is configured to motion correct stationary structure in a series of ultrasound images for subject motion, wherein the series of ultrasound images includes the stationary structure and flowing structure. The stationary structure remover is configured to remove the stationary structure from the motion corrected series of ultrasound images thereby producing flow images of the flowing structure. The flowing structure detector is configured to detect peaks of flow of the flowing structure in the flow images over time to generate images of detected flow peaks. The images of detected flow peaks are accumulated over time to generate a high resolution ultrasound image.
