Quick Recap
We have only a handful of qubits and they are noisy, right? So many people are hard at work trying to solve that. But the “other” elephant in the room is how to connect such qubits. Even if we had today millions of stable and coherent qubits… each of them has a plethora of controlling units, cables, refrigerators and probes. That takes up some space so a 1M qubit device will be bigger than many rooms. We need advances in miniaturization as well as in the qubit itself. But this week Australia may have a something to say about that. Read on…
The Quote of the Week
"There are two possible outcomes: if the result confirms the hypothesis, then you've made a measurement. If the result is contrary to the hypothesis, then you've made a discovery."
Enrico Fermi - physicist. Nobel Prize in Physics laureate.
Featured Content
As an engineer and software developer, I wish I picked up earlier Bob Coecke's Picturing Quantum Processes book in my path into QC.
Doing this at the beginning would have alleviated the steep learning curve into the field! Highly recommended book!
Also, here is a great introduction to ZX-Calculus.

Paper: Unsupervised learning of anomalous diffusion data
The characterization of diffusion processes is a keystone in our understanding of a variety of physical phenomena. Many of these deviate from Brownian motion, giving rise to anomalous diffusion. Various theoretical models exists nowadays to describe such processes, but their application to experimental setups is often challenging, due to the stochastic nature of the phenomena and the difficulty to harness reliable data. The latter often consists on short and noisy trajectories, which are hard to characterize with usual statistical approaches. In recent years, we have witnessed an impressive effort to bridge theory and experiments by means of supervised machine learning techniques, with astonishing results. In this work, we explore the use of unsupervised methods in anomalous diffusion data. We show that the main diffusion characteristics can be learnt without the need of any labelling of the data. We use such method to discriminate between anomalous diffusion models and extract their physical parameters. Moreover, we explore the feasibility of finding novel types of diffusion, in this case represented by compositions of existing diffusion models. At last, we showcase the use of the method in experimental data and demonstrate its advantages for cases where supervised learning is not applicable.
