Three-qubit W state tomography via full and marginal state reconstructions on ibm_osaka
We present a three-qubit quantum state tomography scheme requiring a set of 17 measurements, significantly reducing the experimental overhead compared to the conventional 63 Pauli measurements. Using IBM's 127-qubit open-access quantum processor ibm osaka, we prepare the three-qubit W state and employ our tomography scheme to reconstruct it. Additionally, we implement a two-qubit tomography protocol, involving a set of 7 measurements, on ibm osaka to reconstruct two of the two-qubit marginals o…

CTA: Cross-Task Alignment for Better Test Time Training
Deep learning models have demonstrated exceptional performance across a wide range of computer vision tasks. However, their performance often degrades significantly when faced with distribution shifts, such as domain or dataset changes. Test-Time Training (TTT) has emerged as an effective method to enhance model robustness by incorporating an auxiliary unsupervised task during training and leveraging it for model updates at test time. In this work, we introduce CTA (Cross-Task Alignment), a nov…

Linear stability of the blowdown Ricci shrinker in 4D
We prove that the four-dimensional blowdown shrinking Ricci soliton constructed by Feldman-Ilmanen-Knopf is linearly stable in the sense of Cao-Hamilton-Ilmanen. This provides the first known example of a non-cylindrical linearly stable shrinking Ricci soliton. This offers new insights into the topological behavior of generic solutions to the Ricci flow in four dimensions: on top of reversing connected sums and handle surgeries, they should also undo complex blow-ups. The proof starts from an…

@… Wprowadzanie świadome rytuałów, czy "łamanie" tych wywołujących niepożądane zachowania to też dobra droga.

Raz to właśnie stworzenie całej sytuacji, wywołującej pozytywne skojarzenia - np. danie obserwować, że pakujesz plecak i jej smaczki, przygotowywanie auta na jej oczach itp. co się kończy zawsze dobrym spacerem, pł…
