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…
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…
Comment and correction for "On Explicit Construction of Simplex -designs" by M. S. Baladram
Jakub Czartowski
In [Bal18] a new method of constructing simplex designs based on cyclic group on elements has been proposed. One of the claims put forward therein is existence of 3-point simpl…
Quantum Pushforward Designs
Jakub Czartowski, Karol Życzkowski
Designs, structures connected to averaging with respect to a given measure using finite sets of points, have proven themselves as invaluable tools across the field of quantum infor…
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 ra…
Confident entanglement detection via separable numerical range
Timo Simnacher, Jakub Czartowski, Konrad Szymański +1
We investigate the joint (separable) numerical range of multiple measurements, i.e., the regions of expectation values accessible with (separable) quantum states for given observab…
