Control landscapes for a class of non-linear dynamical systems: sufficient conditions for the absence of traps
Benjamin Russell, Shanon Vuglar, Herschel Rabitz
We establish three tractable, jointly sufficient conditions for the control landscapes of non-linear control systems to be trap free comparable to those now well known in quantum c…
Comparing the Schrödinger and Dirac Descriptions of an Electron in a Uniform Magnetic Field
David Velasco Villamizar, Benjamin Russell
In this article we present a detailed description of an electron in a uniform magnetic field evolving under the Schrödinger equation using ladder operators. Based on this analysis,…
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.…
