WebApr 1, 2024 · With different gate biases, channel electron mobility is varied by PCF scattering. Furthermore, a more negative gate bias and a lower ratio of l g / l s d (gate length/source-drain space) of the device causes the PCF scattering to have stronger influence on channel electron mobility. This work is the first to apply PCF scattering to a … WebResearchers used gate set tomography to show that the processor’s logic gates surpass 99 percent fidelity. The Science. Tiny quantum computing processors built from silicon have finally surpassed 99 percent fidelity in certain logic operations ("gates”). Quantum computers store information in the quantum state of a physical system (in this ...
WebOct 13, 2016 · Gate set tomography (GST) is a tool for characterizing logic operations in a qubit system. By analysing carefully constructed experiments consisting of state preparation, quantum operation sequences, and measurements, it self-consistently characterizes the experimental system. GST operates with minimal assumptions about physical … WebSep 9, 2015 · Quantum gate set tomography (GST) has emerged as a promising method for the full characterization of quantum logic gates. In contrast to quantum process tomography (QPT), GST self-consistently and correctly accounts for state preparation and measurement (SPAM) errors. It therefore provides significantly more accurate estimates …
