The field of classical stochastic processes forms a major branch of mathematics. Stochastic
processes are, of course, also very well studied in biology, chemistry, ecology, geology …

We investigate the conditions under which an uncontrollable background processes may be
harnessed by an agent to perform a task that would otherwise be impossible within their …

Generic non-Markovian quantum processes have infinitely long memory, implying an exact
description that grows exponentially in complexity with observation time. Here, we present a …

In this paper, I argue that the Shrapnel–Costa no-go theorem undermines the last remaining
viability of the view that the fundamental ontology of quantum mechanics is essentially …

The presence of correlations in noisy quantum circuits will be an inevitable side effect as
quantum devices continue to grow in size and depth. Randomized Benchmarking (RB) is …

Despite the brisk pace of progress on physical substrates for quantum information, there
remains little prospect of truly isolating the system of interest from its noisy environment. As …

Any concrete information processing task can be viewed as the sequential manipulation of
information over time, receiving inputs and producing outputs. To accomplish this …

Den galnaste utmaningen jag har gjort har inte varit fallskärmshoppning; segla Amazonas
på en hemlagad flotte; skalning Mt. Everest; eller gräva efter artefakter ovanpå en kulle i en …
