Ensembles of random quantum states tunable from volume law to area law
Héloïse Albot, Sebastian Paeckel
A standard approach to generate random pure quantum states relies on sampling from the Haar measure. However, the entanglement properties of such states present a fundamental chall…
A Tensor Network Framework for Lindbladian Spectra and Steady States
Philipp Westhoff, Mattia Moroder, Ulrich Schollwöck +1
Quantum systems coupled to (non-)Markovian environments attract increasing attention due to their peculiar physical properties. Exciting prospects such as unconventional non-equili…
Probing the Physical Reality of Projective Measurements
Leonard Werner Pingen, Mattia Moroder, Sebastian Paeckel
We propose a protocol to test whether the postulate of a measurement acting as an instantaneous projection onto an eigenstate of the measurement apparatus is compatible with physic…
Photo-induced dynamics with continuous and discrete quantum baths
Zhaoxuan Xie, Mattia Moroder, Ulrich Schollwöck +1
The ultrafast quantum dynamics of photophysical processes in complex molecules is an extremely challenging computational problem with a wide variety of fascinating applications in…
A logical qubit-design with geometrically tunable error-resistibility
Reja H. Wilke, Leonard W. Pingen, Thomas Köhler +1
Breaking the error-threshold would mark a milestone in establishing quantum advantage for a wide range of relevant problems. One possible route is to encode information redundantly…
