According to quantum mechanics, a physical system can be in any linear superposition of its
possible states. Although the validity of this principle is routinely validated for microscopic …

The phase‐space formulation of quantum mechanics has recently seen increased use in
testing quantum technologies, including methods of tomography for state verification and …

One of the central problems for near-term quantum devices is to understand their ultimate
potential and limitations. We address this problem in terms of quantum error mitigation by …

We show that both the classical as well as the quantum definitions of the Fisher information
faithfully identify resourceful quantum states in general quantum resource theories, in the …

Negativity of the Wigner function is arguably one of the most striking non-classical features
of quantum states. Beyond its fundamental relevance, it is also a necessary resource for …

The striking differences between quantum and classical systems predicate disruptive
quantum technologies. We peruse quantumness from a variety of viewpoints, concentrating …

The diverse range of resources which underlie the utility of quantum states in practical tasks
motivates the development of universally applicable methods to measure and compare …

Resource theories provide a general framework for the characterization of properties of
physical systems in quantum mechanics and beyond. Here we introduce methods for the …

The optical cat state plays an essential role in quantum computation and quantum
metrology. Here, we experimentally quantify quantum coherence of an optical cat state by …

We study asymptotic state transformations in continuous variable quantum resource
theories. In particular, we prove that monotones displaying lower semicontinuity and strong …
