A short introduction to Quantum Channels: Characterization and Methods (I)
by - -- 14 Oct '25

14 Oct '25

Desde el Grupo de Termodinámica y Computación Cuántica de la Universidad de Granada invitamos a la comunidad universitaria a participar de una nueva serie de seminarios. La primera sesión será el jueves 16. Speaker: Prof. Michalis Skotiniotis. QTCG-UGR Title: A short introduction to Quantum Channels: Characterization and Methods (I) Abstract: This series of lectures tackles the dynamics of open quantum systems from the point of view of Quantum Channels. These are Completely Positive, Trace Preserving (CPTP) maps acting on the space of linear operators. The first lecture concerns the derivation of the Gorini, Kossakowski, Sudarshan, Lindblad (GKSL) Master Equation from an entirely mathematical point of view using functional analysis. The second lecture concerns the characterization of CPTP maps and particularly their mathematical characterization in terms of the Matrix representation, Kraus representation, Stinespring Representation and Choi-Jamiolkowski representation. The third and final lecture will tackle the question of how to obtain the Kraus representation of a CPTP map given a master equation of GKSL form and present some examples. Date and Time: Thursday 16th of October 2025. 12pm. Place: Laboratorio de Física Computacional. Sección de Física de la Facultad de Ciencias, planta baja (junto al péndulo). Todos nuestros seminarios son posteriormente subidos a nuestro canal de YouTube. https://urldefense.com/v3/__https://www.youtube.com/@qtcg_ugr__;!!D9dNQwwGX… También puede suscribirse a nuestra lista de correo donde publicamos información sobre cursos, seminarios, conferencias, etc. https://onsager.ugr.es/mailman3/mailman3/lists/qtcg-info.onsager.ugr.es/ ————————————————————— Quantum Thermodynamics and Computation Group University of Granada https://ic1.ugr.es/members/qtc/

Topology and strong interactions in non-equilibrium quantum simulators at Institute of Fundamental Physics - CSIC > > PhD project on the theory of topological non-equilibrium phases in quantum simulators. > > Quantum simulators, such as superconducting circuits or trapped ions, enable the creation of new phases of quantum matter. These new phases are important from a fundamental viewpoint, as they challenge our understanding of quantum complex systems. They can also find applications for designing precise sensors and amplifiers. In recent years, our group has developed a novel formalism for describing topological non-equilibrium phases of matter in quantum simulators. However, many questions remain open, like the role of interactions and disorder. This project will develop a theoretical description of complex topological phases based on analytical approaches and numerical algorithms. We will analyse how interactions lead to exotic new topological phases and explore their dynamical and structural properties. > > The ideal candidate will have a solid theoretical background in quantum mechanics, quantum optics, and condensed matter physics. More specifically, you will: > > ● Modelize quantum simulators based on quantum optical setups using theoretical techniques from quantum open systems (master equations, Floquet theory) > ● Analyze quantum phase transitions and topological phases > ● Develop numerical algorithms based on phase-space methods (truncated Wigner approximation) or Matrix Product States to describe interacting phases. Numerical experience with Python is useful here. > > What we offer: > ● Funded PhD position within the 4-year research project (“FPI Grant” funded by the National Project PID2024-159152NB-I00) > ● A stimulating environment: the QUINFOG group at IFF-CSIC (6 faculty, several postdocs/PhDs) > ● Possibilities for international collaborations with theory and experimental groups. > > The search is restricted to students fulfilling the criteria of the call (European citizens > with certification of at least 300 ECTS, or students from outside the European Union > with the Spanish equivalent of 300 ECTS). > > The call is expected to mirror last year’s. Selected candidates will apply to the official > opening expected in November, with PhD start around January 2026 (exact dates > TBA). > > > Web: https://urldefense.com/v3/__https://quinfog.hbar.es/news/two-phd-opportunit…
