Fast gradient estimation for variational quantum algorithms
Lennart Bittel, Jens Watty, Martin Kliesch
Many optimization methods for training variational quantum algorithms are based on estimating gradients of the cost function. Due to the statistical nature of quantum measurements,…
Scalable approach to many-body localization via quantum data
Alexander Gresch, Lennart Bittel, Martin Kliesch
We are interested in how quantum data can allow for practical solutions to otherwise difficult computational problems. A notoriously difficult phenomenon from quantum many-body phy…
Optimal noise estimation from syndrome statistics of quantum codes
Thomas Wagner, Hermann Kampermann, Dagmar Bruß +1
Quantum error correction allows to actively correct errors occurring in a quantum computation when the noise is weak enough. To make this error correction competitive information a…
Simultaneous structures in convex signal recovery - revisiting the convex combination of norms
Martin Kliesch, Stanislaw J. Szarek, Peter Jung
In compressed sensing one uses known structures of otherwise unknown signals to recover them from as few linear observations as possible. The structure comes in form of some compre…
Sample complexity of device-independently certified "quantum supremacy"
Dominik Hangleiter, Martin Kliesch, Jens Eisert +1
Results on the hardness of approximate sampling are seen as important stepping stones towards a convincing demonstration of the superior computational power of quantum devices. The…
Properties of thermal quantum states: locality of temperature, decay of correlations, and more
Martin Kliesch, Arnau Riera
We review several properties of thermal states of spin Hamiltonians with short range interactions. In particular, we focus on those aspects in which the application of tools coming…
