A Quantum Algorithm for -Transport on Flat Connection Graphs
Stacey Jeffery, Tobias J. Osborne, Galina Pass
We study a generalization of undirected -connectivity to graphs whose edges carry quantum operations. Let be an undirected graph on vertices in which each edge $\…
Quantum steering is equivalent to state-preserving conditional expectations
Lauritz van Luijk, Amine Marrakchi, Tobias Osborne +2
In systems with infinitely many degrees of freedom, fundamental results from quantum information theory can fail. An important example is the uniqueness of purifications: Even when…
Monte Carlo Graph Search for Quantum Circuit Optimization
Bodo Rosenhahn, Tobias J. Osborne
The building blocks of quantum algorithms and software are quantum gates, with the appropriate combination of quantum gates leading to a desired quantum circuit. Deep expert knowle…
On the renormalization group fixed point of the two-dimensional Ising model at criticality
Tobias J. Osborne, Alexander Stottmeister
We analyze the renormalization group fixed point of the two-dimensional Ising model at criticality. In contrast with expectations from tensor network renormalization (TNR), we show…
Quantum simulation of dynamical phase transitions in noisy quantum devices
Younes Javanmard, Ugne Liaubaite, Tobias J. Osborne +1
Zero-noise extrapolation provides an especially useful error mitigation method for noisy intermediate-scale quantum devices. Our analysis, based on matrix product density operators…
Reviving product states in the disordered Heisenberg chain
Henrik Wilming, Tobias J. Osborne, Kevin S. C. Decker +1
When a generic quantum system is prepared in a simple initial condition, it typically equilibrates toward a state that can be described by a thermal ensemble. A known exception are…
