Dependence of the Quantum Speed Limit on System Size and Control Complexity

Autor: Lee, Juneseo, Arenz, Christian, Rabitz, Herschel, Russell, Benjamin

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 system with an arbitrary number of classical control fields. This bound i

Control landscapes for a class of non-linear dynamical systems: sufficient conditions for the absence of traps

Autor: Russell, Benjamin, Vuglar, Shanon, Rabitz, Herschel

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 control. In particular, our results encompass end-point control problem

Comparing the Schr\'odinger and Dirac Descriptions of an Electron in a Uniform Magnetic Field

Autor: Villamizar, David Velasco, Russell, Benjamin

In this article we present a detailed description of an electron in a uniform magnetic field evolving under the Schr\"odinger equation using ladder operators. Based on this analysis, we describe the same physical system using the Dirac equation, know

The roles of drift and control field constraints upon quantum control speed limits

Autor: Arenz, Christian, Russell, Benjamin, Burgarth, Daniel, Rabitz, Herschel

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. The bound depends on the target gate, the strength of the internal Ha
