Trading athermality for nonstabiliserness
A. de Oliveira Junior, Rafael A. Macedo, Jakub Czartowski +2
Quantum advantage arises from quantum states that cannot be efficiently simulated on a classical computer. Such states are characterised by a property known as nonstabiliserness. I…
Quantum convolutional channels and multiparameter families of 2-unitary matrices
RafaÅ BistroÅ, Jakub Czartowski, Karol Å»yczkowski
Many alternative approaches to construct quantum channels with large entangling capacity were proposed in the past decade, resulting in multiple isolated gates. In this work, we pu…
Manipulating heterogeneous quantum resources over a network
Ray Ganardi, Jeongrak Son, Jakub Czartowski +2
Quantum information processing relies on a variety of resources, including entanglement, coherence, non-Gaussianity, and magic. In realistic settings, protocols run on networks of…
Relative volume of comparable pairs under semigroup majorization
Fabio Deelan Cunden, Jakub Czartowski, Giovanni Gramegna +1
Any semigroup of stochastic matrices induces a semigroup majorization relation on the set of probability -vectors. Pick at r…
Approximate pushforward designs and image bounds on approximations
Jakub Czartowski, Adam Sawicki, Karol Życzkowski +1
We extend the framework of quantum pushforward designs to the approximate setting, in which moment operators agree only up to finite precision. We first formulate a general transfe…
Efficient state estimation on quantum processors
Victor Gonzalez Avella, Abraham Vega Vargas, Tomas Merlo Vergara +6
We present two scalable and entanglement-free methods for estimating the collective state of an n-qubit quantum computer. The first method consists of a fixed set of five quantum c…
