Tuesday, October 15, 2024 11:00 MLIT Room 310, Online meeting via Webinar Online meeting in Webinar Alexander Yakovlev Development, creation and further evolution of the Event Picking Service within the ATLAS Event Index project Abstract: Event Picking Service, intended for mass selection of events from a set of ATLAS data, has been developed and launched into operation as part of the ATLAS Event Index project. During physical analysis, it is often necessary to extract a large number of specified events in order to study their properties using alternative or improved algorithms. The Event Picking service automates the procedure of searching and extracting individual events from the files in which they are stored and providing them to the service user. Yuri Palii Comparison of various optimization methods in the quantum QAOA algorithm for the Ising model Abstract: A simulation of the operation of the quantum approximation optimization algorithm (QAOA) examplified by searching for the state with the lowest energy in the Ising model with a longitudinal magnetic field on a simulator of quantum computing in the Cirq environment. The wavefunction ansatz, containing 6 parameters, was used to calculate the energy value, which was minimized via methods taken from the SciPy Optimization library. It is shown that modeling the measurement of the states of all register qubits requires more computer memory, but less calculation time compared to the Hadamard test, in which only the state of one additional qubit is measured.
