Barren plateaus are swamped with traps
Title: Barren plateaus are swamped with traps
Speaker: Nikita A. Nemkov from National University of Science and Technology “MISIS”
Abstract:
Two main challenges preventing efficient training of variational quantum algorithms and quantummachine learning models are local minima and barren plateaus. Typically, barren plateaus areassociated with deep circuits, while shallow circuits have been shown to suffer from suboptimallocal minima. We point out a simple mechanism that creates exponentially many poor local minimaspecifically in the barren plateau regime. These local minima are trivial solutions, optimizing onlya few terms in the loss function, leaving the rest on their barren plateaus. More ...

Title: Entanglement-enabled advantage for learning a bosonic random displacement channel Author: Changhun Oh from Korea Advanced Institute of Science and Technology Abstract: We show that quantum entanglement can provide an exponential advantage in learning properties of a bosonic continuous-variable (CV) system. The task we consider is estimating a probabilistic mixture of displacement operato...

Title: Dissipation as a resource for quantum reservoir computing Speaker: Antonio Sannia from Campus Universitat de les Illes Balears Abstract: Dissipation induced by interactions with an external environment typically hinders the performance of quantum computation, but in some cases can be turned out as a useful resource. We show the potential enhancement induced by dissipation in the field of...
Noise induced shallow circuits and absence of barren plateaus

Title: Noise-induced shallow circuits and absence of barren plateaus Speaker: Antonio Anna Mele from Freie Universitat Berlin Abstract: Motivated by realistic hardware considerations of the pre-fault-tolerant era, we comprehensively study the impact of uncorrected noise on quantum circuits. We first show that any noise `truncates' most quantum circuits to effectively logarithmic depth, in the t...

Title: Mapping out phase diagrams with generative classifiers Speaker: Julian Arnold from University of Basel Abstract: One of the central tasks in many-body physics is the determination of phase diagrams. However, mapping out a phase diagram generally requires a great deal of human intuition and understanding. To automate this process, one can frame it as a classification task. Typically, clas...

Title: Random Natural Gradient Speaker: Ioannis Kolotouros from University of Edinburgh Abstract: Hybrid quantum-classical algorithms appear to be the most promising approach for near-term quantum applications. An important bottleneck is the classical optimization loop, where the multiple local minima and the emergence of barren plateaux make these approaches less appealing. To improve the opti...
