SUMMARY:Семинар на МЦМН
DESCRIPTION:Дата: 13.02.2024 г.\, 14:00 ч. \nМясто: Зала 403\, ИМИ – БАН \nДокладчик: Jean-Pierre Gazeau (APC\, Université Paris – Cité) \nДоклад: Quantum circuit complexity for light polarisation or complexity with no complex numbers \nДопълнителна информация: https://icms.bg/quantum-circuit-complexity-for-light-polarisation-or-complexity-with-no-complex-number-talk-by-jean-pierre-gazeau/ \nРезюме. I will present a form of quantum circuit complexity that extends to open systems. To illustrate the methodology\, I focus on a basic model where the Hilbert space of states is represented by the Euclidean plane. Specifically\, the investigation is about the dynamics of mixed quantum states as they undergo interactions with a sequence of gates. The approach involves the analysis of sequences of density matrices. Each density matrix evolves within the framework of a Gorini-Kossakowski-Lindblad-Sudarshan (GKLS) process during the time interval between consecutive gates. Notably\, when considering an upper limit for the cost function\, the optimal number of gates follows a power-law relationship.
