Inclusion constants for free spectrahedra with applications to quantum incompatibility
Andreas Bluhm, Eric Evert, Igor Klep +2
Building on the matrix cube problem, inclusions of free spectrahedra have been used successfully to obtain relaxations of hard spectrahedral inclusion problems. The quality of such…
Random measurements are almost maximally incompatible
Andreas Bluhm, Cécilia Lancien, Ion Nechita
In this work, we investigate the incompatibility of random quantum measurements. Most previous work has focused on characterizing the maximal amount of white noise that any fixed n…
Random covariant quantum channels
Ion Nechita, Sang-Jun Park
The group symmetries inherent in quantum channels often make them tractable and applicable to various problems in quantum information theory. In this paper, we introduce natural pr…
On the simulation of quantum multimeters
Andreas Bluhm, Leevi Leppäjärvi, Ion Nechita
In the quest for robust and universal quantum devices, the notion of simulation plays a crucial role, both from a theoretical and from an applied perspective. In this work, we go b…
Generating random Gaussian states
Leevi Leppäjärvi, Ion Nechita, Ritabrata Sengupta
We develop a method for the random sampling of (multimode) Gaussian states in terms of their covariance matrix, which we refer to as a random quantum covariance matrix (RQCM). We a…
Monogamy of highly symmetric states
Rene Allerstorfer, Matthias Christandl, Dmitry Grinko +4
We investigate the extent to which two particles can be maximally entangled when they are also similarly entangled with other particles on a complete graph, focusing on Werner, iso…
