Multipartite entanglement dynamics in quantum walks
Emil K. F. Donkersloot, René Sondenheimer, Jan Sperling
Quantum walks constitute a rich area of quantum information science, where multipartite entanglement plays a central role in the dynamics and scalability of quantum advantage over…
Quantifying entanglement in quantum thermodynamics via separability constraints
Joan Alba, Laura Ares, Jan Sperling +1
The role of quantum entanglement in thermodynamical systems remains elusive. Does entanglement result in thermodynamic advantages or does it impose fundamental limitations? Here, w…
Quantum speedup from nonclassical polarization
Tim Aßbrock, Jan Sperling, Laura Ares
We develop a framework for identifying nonclassical speedups in systems with polarization, likewise spin degrees of freedom. By confining the dynamics to the manifold of angular mo…
The entangling power of non-entangling channels
Julien Pinske, Jan Sperling, Klaus Mølmer
There are processes that cannot generate entanglement but may, nevertheless, amplify entanglement already present in a system. Here, we show that a non-entangling operation can inc…
Restricted Monte Carlo wave function method and Lindblad equation for identifying entangling open-quantum-system dynamics
Laura Ares, Julien Pinske, Benjamin Hinrichs +2
We develop an extension of the Monte Carlo wave function approach that unambiguously identifies dynamical entanglement in general composite, open systems. Our algorithm performs ta…
Separability Lindblad equation for dynamical open-system entanglement
Julien Pinske, Laura Ares, Benjamin Hinrichs +2
Providing entanglement for the design of quantum technologies in the presence of noise constitutes today's main challenge in quantum information science. A framework is required th…
Entangled quantum trajectories in relativistic systems
Yannick Noel Freitag, Julien Pinske, Jan Sperling
Quantum entanglement is a key resource for quantum technologies, including emerging ground-to-satellite quantum communication. In such a scenario, an important challenge to be over…
Unbreakable and breakable quantum censorship
Julien Pinske, Jan Sperling
A protocol for regulating the distribution of quantum information between multiple parties is put forward. In order to prohibit the unrestricted distribution of quantum-resource st…
Witnessing random unitary and projective quantum channels: Complementarity between separable and maximally entangled states
D. Bruns, J. Sperling, S. Scheel
Modern applications in quantum computation and quantum communication require the precise characterization of quantum states and quantum channels. In practice, this means that one h…
