Controlling qubit networks in polynomial time
Christian Arenz, Herschel Rabitz
Future quantum devices often rely on favourable scaling with respect to the system components. To achieve desirable scaling, it is therefore crucial to implement unitary transforma…
Dynamical Decoupling of Unbounded Hamiltonians
Christian Arenz, Daniel Burgarth, Paolo Facchi +1
We investigate the possibility to suppress interactions between a finite dimensional system and an infinite dimensional environment through a fast sequence of unitary kicks on the…
The roles of drift and control field constraints upon quantum control speed limits
Christian Arenz, Benjamin Russell, Daniel Burgarth +1
In this work we derive a lower bound for the minimum time required to implement a target unitary transformation through a classical time-dependent field in a closed quantum system.…
Lindbladian purification
Christian Arenz, Daniel Burgarth, Vittorio Giovannetti +2
In a recent work [D. K. Burgarth et al., Nat. Commun. 5, 5173 (2014)] it was shown that a series of frequent measurements can project the dynamics of a quantum system onto a subspa…
