Complexity of Quadratic Bosonic Hamiltonian Simulation: -Completeness and -Hardness
Lilith Zschetzsche, Refik Mansuroglu, Norbert Schuch
The computational complexity of simulating the dynamics of physical quantum systems is a central question at the interface of quantum physics and computer science. In this work, we…

Direct Equivalence between Dynamics of Quantum Walks and Coupled Classical Oscillators
Lilith Zschetzsche, Refik Mansuroglu, András Molnár +1
Continuous time quantum walks on exponentially large, sparse graphs form a powerful paradigm for quantum computing: On the one hand, they can be efficiently simulated on a quantum…

Suppression of polaron self-localization by correlations
Lilith Zschetzsche, Robert E. Zillich
We investigate self-localization of a polaron in a homogeneous Bose-Einstein condensate in one dimension. This effect, where an impurity is trapped by the deformation that it cause…
