Robust characterization of average gate set noise and cross-talk using gate-set shadows
Jadwiga Wilkens - Johannes Kepler University of Linz
As quantum processors scale, robust and scalable tools to characterize gate-level noise become indispensable. Randomized benchmarking (RB) and its many variants have emerged as the go-to protocols in practice: they yield a single number to characterize a gate set, the average gate fidelity, per… -

Wilsonian Renormalization of Neural Network Field Theories
Zohar Ringel - Hebrew University of Jerusalem
Neural scaling laws and hyperparameter transfer scaling laws play an increasingly dominant role in deep learning. In physics, scaling behaviour pointed directly to the Wilsonian Renormalisation Group (RG). In this seminar talk, I'll present our ongoing efforts to build an RG framework for deep… -

Scattering matrices for noncommutative instantons
Spencer Tamagni - University of California, Berkeley
The assignment of scattering data to monopoles is a classical construction in gauge theory useful to understand the geometry of monopole moduli spaces; from the modern perspective, it is of interest because monopole scattering matrices are quasiclassical limits of R-matrices of shifted Yangians. I… -
Quantum Geometry of the Light Cone
Wolfgang Wieland - University of Erlangen-Nuremberg
In Einstein's theory of general relativity, the causal structure of spacetime is itself dynamical. Causality is encoded into the geometry of light cones that bend under the influence of gravity. Quantum theory, on the other hand, tells us that nature is intrinsically probabilistic. A sharply defined… 
Beyond Measurement: Exponential Advantages in Coherent Quantum Inference
Zhaoyi Li
Quantum inference usually begins by measuring quantum data and converting it into classical information. In this talk, I will consider a different setting in which the desired output remains quantum, allowing coherence to be preserved throughout the inference process. Examples include quantum purity…-
