A goal of cone-beam CT is to decrease the scan time needed to image a volume of the patient. Four things are required to meet this goal: (1) a detector with multiple rows of sensors, (2) higher bandwidth data acquisition system and image processor to handle the increased data rates and need for fast reconstruction, (3) high helical pitch, (4) a practical reconstruction algorithm that lends itse...
Arrays of multi-segmented hybrid nanostructures of carbon nanotube and gold nanowires have been synthesized using a combination of chemical vapour deposition and electrodeposition methods and we further demonstrate that ultra-high power electrochemical double layer capacitors can be engineered using these hybrid nanowires, resulting in very high power densities.
Single-photon-detector arrays can provide unparalleled performance and detailed information in applications that require precise timing and single photon sensitivity. Such arrays have been demonstrated using a number of single-photon-detector technologies, but the high performance of superconducting nanowire single photon detectors (SNSPDs) and the unavoidable overhead of cryogenic cooling make...
Two-dimensional arrays of solid state detectors have long been used in visible and infrared systems. Hybrid arrays with separately optimized detector and readout substrates have been extensively developed for infrared sensors. The characteristics and use of these infrared readout chips with silicon PIN diode arrays produced by MICRON SEMICONDUCTOR for detecting high-energy particles are reporte...
Atomic ions confined in segmented trap arrays provide a system for quantum information processing. We report on the execution of two simple quantum algorithms, quantum error correction and the quantum Fourier transform, using this implementation. The demonstration of these algorithms in a scalable system is one step towards the execution of useful, large-scale quantum algorithms.
