(English) Weekly Quantum Group Webinar: Dr Garry Kemp, A generalized dominance ordering for 1/2-BPS states

Zoom

Title of talk: A generalized dominance ordering for 1/2-BPS states. Speaker: Dr Garry Kemp. Abstract: I discuss a generalized dominance ordering for irreducible representations of the symmetric group $S_{n}$ with the aim of distinguishing the corresponding states in the 1/2-BPS sector of $U(N)$ Super Yang-Mills theory when a certain finite number of Casimir operators are …

(English) Weekly Quantum Group Webinar: Dr Latévi M. Lawson, Path integral in position deformed Heisenberg algebra

Zoom

Title of talk: Path integral in position deformed Heisenberg algebra. Speaker: Dr Latévi M. Lawson. Abstract: The deformed Heisenberg algebra is one of the promising candidate approaches to probe quantum gravity at the Planck scale. It consists of deforming the ordinary Heisenberg algebra in momentum or in position operators. Recently, we proposed in , a …

(English) Weekly Quantum Group Webinar: Abhishek Agarwal, Modelling non-Markovian noise in driven superconducting qubits

Zoom

Title of talk: Modelling non-Markovian noise in driven superconducting qubits. Speaker: Abhishek Agarwal Abstract: Non-Markovian noise can be a significant source of errors in superconducting qubits. We develop gate sequences utilising mirrored pseudoidentities that allow us to characterise and model the effects of non-Markovian noise on both idle and driven qubits. We compare three approaches to modelling …

(English) Quantum Seminar/Webinar: Rivan Rughubar (UCT): Approximating classical kernels on NISQ computers

Stellenbosch University, Physics Department School of Data Science and Computational Thinking, Stellenbosch

Rivan Rughubar (UCT) Approximating classical kernels on NISQ computers Abstract: The talk will aim to demonstrate how a kernel function can be approximated on a NISQ computer and to demonstrate the limitations of this method. Kernel methods are used throughout classical and quantum machine learning. Over the last few years there has also been much …

(English) Seminar: Prof Nadja Bernardes, Approximating Invertible Maps by Recovery Channels: Optimality and an Analysis of Qudit Channels

Stellenbosch University, Physics Department School of Data Science and Computational Thinking, Stellenbosch

Title of talk: Approximating Invertible Maps by Recovery Channels: Optimality and an Analysis of Qudit Channels Speaker: Prof Nadja Bernardes (Federal University of Pernambuco, Brazil) Abstract: We investigate the problem of reversing quantum dynamics, specifically via optimal Petz recovery maps. We focus on typical decoherence channels, such as dephasing, depolarizing, and amplitude damping. We illustrate how well …
