Combining the synergistic control capabilities of modelling and experiments: illustration of finding a minimum time quantum objective
Qi-Ming Chen, Xiaodong Yang, Christian Arenz +4
A common way to manipulate a quantum system, for example spins or artificial atoms, is to use properly tailored control pulses. In order to accomplish quantum information tasks bef…
Quantum Control Landscape of Bipartite Systems
Robert L. Kosut, Christian Arenz, Herschel Rabitz
The control landscape of a quantum system interacting with another quantum system is studied. Only system is accessible through time dependent controls, while system B…
Amplification of quadratic Hamiltonians
Christian Arenz, Denys I. Bondar, Daniel Burgarth +2
Speeding up the dynamics of a quantum system is of paramount importance for quantum technologies. However, in finite dimensions and without full knowledge of the details of the sys…
Dependence of the Quantum Speed Limit on System Size and Control Complexity
Juneseo Lee, Christian Arenz, Herschel Rabitz +1
We extend the work in New J. Phys. 19, 103015 (2017) by deriving a lower bound for the minimum time necessary to implement a unitary transformation on a generic, closed quantum sys…
