Genuine Multipartite Entanglement in Time
Simon Milz, Cornelia Spee, Zhen-Peng Xu +3
While spatial quantum correlations have been studied in great detail, much less is known about the genuine quantum correlations that can be exhibited by temporal processes. Employi…
The dark side of energy transport along excitonic wires: On-site energy barriers facilitate efficient, vibrationally-mediated transport through optically dark subspaces
Scott Davidson, Amir Fruchtman, Felix Pollock +1
We present a novel, counter-intuitive method, based on dark state protection, for significantly improving exciton transport efficiency through `wires' comprising a chain of molecul…
A discrete memory-kernel for multi-time correlations in non-Markovian quantum processes
Mathias R. Jørgensen, Felix A. Pollock
Efficient simulations of the dynamics of open systems is of wide importance for quantum science and tech-nology. Here, we introduce a generalization of the transfer-tensor, or disc…
Demonstration of non-Markovian process characterisation and control on a quantum processor
Gregory A. L. White, Charles D. Hill, Felix A. Pollock +2
In the scale-up of quantum computers, the framework underpinning fault-tolerance generally relies on the strong assumption that environmental noise affecting qubit logic is uncorre…
Resource theories of multi-time processes: A window into quantum non-Markovianity
Graeme D. Berk, Andrew J. P. Garner, Benjamin Yadin +2
We investigate the conditions under which an uncontrollable background processes may be harnessed by an agent to perform a task that would otherwise be impossible within their oper…
An algorithm for solving unconstrained unitary quantum brachistochrone problems
Francesco Campaioli, William Sloan, Kavan Modi +1
We introduce an iterative method to search for time-optimal Hamiltonians that drive a quantum system between two arbitrary, and in general mixed, quantum states. The method is base…
